Comment Save Our Water
W
ATER conservation issues and the effects of pollution on native wildlife and habitats were major concerns of delegates at Forest & Bird’s North and South Island meetings held in November. These and other issues affecting water quality would be better addressed through more integrated water catchment management. In some quarters this simply means planting trees and claiming carbon credits. But the term includes the recognition of the importance of plants in intercepting rainfall, aiding water absorption via the roots, and affecting humidity through leaf transpiration. It also relates to the wider water cycle issues of soil water and run-off and thus to the whole subject of soil maintenance and reducing erosion. Integrated catchment management has beneficial effects on the maintenance of water tables and aquifers, streams and rivers, and the final discharge through estuaries and the coastal area. It has to do with the whole freshwater ecology – the plants and animals, including humans – and their interactions throughout the catchment area. The large-scale take of water for various industries, notably dairying, can have serious effects on the environment. There is particular concern about increasing demand for water from South Island dairy conversions, compounded by the ongoing proposals for more hydroelectric development. What chances have our specialised braided river birds such as wrybill, pied oystercatcher and black-fronted tern, against these juggernauts of “progress”? Ah! But we are told “we are only proposing
lowering the river by a few centimetres” – but this simply means so that the predators (cats and stoats) don’t even need to get their feet wet to have an easy feed! Forest & Bird has cautioned against further loss of wetland habitats over the years. Now it is time to say enough is enough and to insist on the vital importance of wetlands in catchment management and water management in general. The loss of forest cover and “drainage of the land” has resulted in soil erosion, rapid run-off, large-scale siltation of our streams and rivers, flooding of lowland areas and massive build-up of sediment in estuaries and coastal areas. It is time to campaign not only for “minimum flows” but for the restoration of our wetlands and waterways. This is what Forest & Bird branches in the Manawatu area are campaigning for to save and restore the mighty Manawatu River! Advocating for solutions such as riparian planting has long been on Forest & Bird’s agenda. Now we must also promote the concept of restoring stream and lake ecosystems to bring back healthy populations of wetland plants, insects, fish and birds. Doing so may also mean restoring fish passage up- or down-stream. Congratulations to the Native Freshwater Fish Society and particularly to Dean Andre, Chairman of South Auckland Branch, for championing these issues, and also to the Upper Hutt Branch for the Hulls Creek restoration work. The loss of urban streams from pollution or containment in pipes has been an ongoing and often little-noticed consequence of rapid urbanisation and development. Fighting for the remaining streams and wetlands and making these attractive and “safe” for wildlife are yet further battles. Stormwater retention
ponds can become good wildlife habitat, but all too often they become silt-laden ponds, blighted by toxic algal blooms and dangerous to wildlife and people. Finally, don’t forget the impact of all the silt and nutrient washing into marine environments. This, combined with increasing coastal development, puts pressure on those special coastal environments – from estuaries to mudflats and salt marshes. Some specialised plants and animals are gone or going. Birds that nest on and feed near our shores, like little blue penguins, are losing out. Internationally there are concerns about those migratory species that depend on coastal mudflats here in New Zealand and throughout their East Asian-Australasian migratory flyway. These birds are losing habitat all along the way – from increased predator activity and climate change affecting their Arctic tundra breeding sites – to the loss of large areas of mudflat in Asia and Australasia through intensive development. So please consider how you can help with the many and varied projects that will form part of Forest & Bird’s conservation campaigns this year. Thank you. National President Dr Peter Maddison

HE Department of Conservation (DOC) is preparing to trial artificial insemination this kakapo breeding season in a bid to help boost numbers and increase genetic diversity within the species’ small population. The sound of booming male kakapo this summer will herald the start of the breeding season on Codfish Island/Whenua Hou, an island sanctuary located three kilometres off the coast of Stewart Island. Following matings in February and March, it is hoped that the females will nest in late summer, giving DOC staff their first opportunity to trial artificial insemination techniques to improve egg fertility and genetic variation. The Kakapo Recovery Programme, which is a partnership between DOC, Forest & Bird and Rio Tinto Alcan (formerly Comalco), is optimistic about this breeding
season because of the presence of rimu fruit and the return of the Spanish avian artificial insemination expert, Dr Juan Blanco, both of which are seen as being pivotal for the continued survival of the critically endangered kakapo. DOC hopes to use sperm from Richard Henry, a kakapo discovered in Fiordland, and at a later stage his two male offspring, to increase the genetic diversity of the population with Fiordland kakapo genes. Dominant male kakapo have more success attracting female kakapo, resulting in an overrepresentation of some males’ genes in the population. Artificial insemination will provide greater control over the gene pool. Female kakapo that copulate more than once have a higher fertility rate, and by introducing the technique employed by Dr Blanco, the programme can ensure females mate more than once, and manage which sperm fertilises an egg.

IWI have relatively large brains similar to “smarter” birds that have retained the power of flight, whereas extinct moa species had significantly smaller brains, like other flightless birds such as ostrich and emu. Research conducted at The University of Auckland examined the brain size of several species of flightless “old birds” (Palaeognaths), including North Island brown kiwi, Stewart Island tokoeka, African ostrich, Australian emu, South American tinamou and extinct New Zealand moa.

High country lakeside land protected
F
OREST & Bird has welcomed a comprehensive list issued by the Government of high country lakeside properties to be protected from inappropriate development. In November Land Information Minister David Parker identified 65 lakeside properties in the South Island where tenure review should not proceed because the properties have highly significant values that should be protected. Thirty-eight of the properties had already begun tenure review, but this would cease in almost all cases, the minister said. However, some lakeside properties might still be considered for tenure review if a leaseholder met conditions, including lakeside land being retained by the Crown, or restrictions on future development. Under tenure review, holders
of pastoral leases receive freehold parts of former leasehold land in exchange for other parts going into the conservation estate. Forest & Bird Advocacy Manager Kevin Hackwell said the announcement of the list meant there would not be a repeat of iconic lakeside property being privatized and then threatened with development, as happened at Richmond. He said Forest & Bird was disappointed there was no equivalent list for properties with important biodiversity and landscape values. “However, we are pleased with the clear signal it sends: that unless values can be adequately protected through tenure review, the properties will remain as pastoral leases.” Helen Bain

skulls to estimate, and direct measurement, where complete specimens existed, the size of these bird species’ brains was calculated relative to their body weights. The results, published in the journal “Brain, Behaviour and Evolution” (Issue 71, 2008), show that kiwi have a similar brain-body ratio to “new birds” (Neognaths), whereas other Palaeognaths, including moa, had a smaller than expected brain compared to body weight. “In fact the size of the kiwi cerebral hemisphere compared to total brain size is rivalled only by a handful of ‘smart’ birds, such as songbirds and parrots, despite a lack of any known advanced behavioural abilities in kiwi,” says Dr Fabiana Kubke of the Department of Anatomy.
World Wetlands Day 2008
W
ORLD Wetlands Day is held every year on 2 February to celebrate the Ramsar Convention on Wetlands, which was signed in Ramsar, Iran, in 1971 to coordinate international efforts to conserve wetlands. New Zealand is a signatory of the Convention, but has just six Ramsar listed wetlands of international importance. This number would be much higher if all our important wetlands were properly recognised and protected. For example, Kaipara Harbour, which is an important site for migratory wading birds, and various South Island braided river systems like the Wairau and Rakaia Rivers, which are important for rare endemic species including wrybill, black-fronted tern and black-billed gull. In addition to their importance as habitat for these native species, this year’s celebrations highlighted the direct, positive effects on human health of maintaining healthy wetlands under the theme of Healthy Wetlands, Healthy People – as well as the direct negative effects of mismanaging them, which can result in the impairment of human health and, in some circumstances, loss of life. All over the world wetlands are important for human health in protecting human habitation from weather extremes, and providing food, clean water and certain pharmaceutical products – so the destruction of
wetlands can also bring about a decline of these valuable healthgiving services. Maintaining wetlands, rather than draining them or cutting down the native plants found in them to make way for development, provides a buffer zone of protection against some of the serious storms, floods, droughts and erosion which New Zealand has experienced in recent years. With climate change these weather extremes are likely to become even more frequent – and the protection provided by wetlands even more important. Although wetlands are one of New Zealand’s most important habitats and provide these important health benefits, they have almost been wiped out in the last 200 years. Fewer than 10% of our wetlands remain and their destruction continues. Once wetlands are gone they can be difficult – but not impossible – to restore to their former state. The Pauatahanui wetland, north of Wellington, had been drained and was used as farmland and a go-kart track 20 years ago. Today, thanks to the efforts of Forest & Bird and others, it has been restored to a wonderful wetland which supports a wealth of native plant and bird life including royal spoonbills and bar-tailed godwits. It is living proof that we can restore health to wetlands – and people. Helen Bain w w w. f o r e s t a n d b i r d . o r g . n z

Antarctic penguins on thin ice LOBAL warming now threatens the survival of four penguin species which breed in Antarctica. A new report, “Antarctic Penguins and Climate Change”, published at the UN conference on climate change in Bali in December by WWF, has found that global warming threatens the survival of the emperor, gentoo, chinstrap and Adélie penguins that breed on the Antarctic peninsula. Melting sea ice means these species are losing Antarctic nesting grounds, while overfishing is making their food increasingly scarce according to the report. The Antarctic peninsula is warming five times faster that the average rate of global warming and the waters of the Southern Ocean have become warmer as deep as 3000 metres, it also found. The area of sea ice cover has decreased by 40% over the past 26 years off the west Antarctic
peninsula. This decrease has reduced numbers of krill, the main source of food for chinstrap penguins. Some chinstrap colonies have been reduced in number by up to two-thirds because less food has made it more difficult for young penguins to survive, the report said. Gentoo penguin numbers have also shrunk because they are increasingly dependent on krill as their usual food sources have been depleted by overfishing, the report said. On the north-western coast of the Antarctic peninsula, populations of Adélie penguins have declined by 65% over 25 years. The emperor penguin, the largest penguin species in the world, has seen some of its colonies halved in the past century as warmer temperatures and stronger winds force them to rear their chicks on increasingly thin ice, the report said.

Hihi hatch at Ark in the Park

RK in the Park was delighted to announce in December the hatching of the first stitchbird (hihi) chicks on the Auckland mainland in more than a century. Hihi transferred to the Ark in the Park site in the Waitakere Ranges earlier in 2007 hatched their first chicks in November. Ark in the Park Project Manager Sandra Jack says volunteers were thrilled with the arrival of the first “Westie chicks”. “The fact that the first generation of ‘immigrants’ brought to the Waitakere Ranges from Tiritiri Matangi Island is breeding successfully
is a good sign that they have adapted well to their new home and are thriving.” The 59 mostly juvenile hihi were transferred to Cascade Kauri Park, home of the joint Forest & Bird and Auckland Regional Council community restoration project, following an intensive programme of pest control that means the birds are more likely to survive on the mainland without being preyed on by introduced pests such as possums, rats and stoats. The transfer was the first time hihi had lived on the Auckland mainland since their populations were wiped out by predators in the late1800s.

The new Environment Minister is Trevor Mallard (right), MP for Wainouiomata, who is also Minister of Broadcasting, Labour, Stateowned Enterprises and Associate Finance Minister. Steve Chadwick (left), MP for Rotorua, is the new Minister of Conservation, as well as Minister of Women’s Affairs and Associate Health Minister. Former Conservation
Minister Chris Carter is now Minister of Education and Ethnic Affairs. David Parker, who was Acting Environment Minister, is now Minister of State Services, Energy and Land Information, and Minister Responsible for Climate Change Issues.
Auckland Regional Council Parks and Heritage Committee Chair Sandra Coney says it is wonderful to see hihi chicks appearing in the Ark in the Park so soon. “It’s great to see the hihi have settled in so well they are reproducing, and it will be a special experience for visitors if they spot one of the fledgling birds. It is especially impressive
as we did not know how these translocated birds would do in an unfenced area.” “The Ark in the Park continues to go from strength to strength and much of this comes down to the dedication of the volunteers and Forest & Bird members who initiated the project,” she says. Helen Bain

Whio pair with ducklings
Blue duck numbers up at Kahurangi and Tongariro
N
UMBERS of blue duck (whio) have increased dramatically in Kahurangi National Park, thanks to increased protection under the Department of Conservation’s (DOC) Operation Ark programme. DOC’s goal at the Wangapeka-Fyfe site is to establish a viable whio population of 50 pairs. When the programme began on the Rolling River in the Wangapeka Catchment in 2003, just three whio lived on the river; now there are 28.
When the programme was extended to the Fyfe River in 2006, only two pairs of whio were present; now there are 12 whio on the river. The Operation Ark programme involves trapping to protect nesting females and their young from being preyed on by stoats. Under Operation Nest Egg, 22 whio ducklings have also been hatched from eggs taken from the wild and hand-reared at Peacock Springs Wildlife Centre in Christchurch before being released back at the
Wangapeka-Fyfe site once they are a few months old. In the North Island, protection of whio has also been yielding results on the Tongariro River, where DOC staff have been following the progress of seven whio ducklings and their parents, which have been found as new residents near the Blue Pool on the river. DOC is asking the public to keep an eye out for whio on the river and report any sightings – and to make sure all dogs are kept under control in the area.

NVASIVE predators such as cats and rats are to be eradicated from some of Fiji’s most important seabird islands, as part of a project undertaken by BirdLife International’s Fiji programme, with the support of local landowners and funding from the David and Lucile Packard Foundation. The Ringgold Isles, a remote archipelago forming an outlier group to Vanua Levu, are mostly uninhabited, and their relative isolation should make them a safe haven for seabirds like the black noddy and redfooted booby. The first phase of the project, a survey to establish seabird numbers and the presence of invasive predators, was completed by BirdLife staff in August 2007, with local community assistance. The survey provides baseline data which will enable pre- and post-eradication monitoring to be carried out. “The survey has confirmed that these islands are among Fiji’s most important for seabirds, and once the data has been analysed some islands will also meet criteria for internationally important bird areas (IBAs),” said Vilikesa Masibalavu, who manages BirdLife’s Fiji programme. “The large seabird populations

include many thousands of black and brown noddy, hundreds of brown and red-footed booby, and lesser frigatebird.” Also present were masked booby, black-naped tern and white tern. Rats were found on seven of the eight islands surveyed. On six islands the rat population was found to be “medium to high”. Cats were also found on one island. “Rats eat bird eggs and chicks, whereas cats can quickly decimate an entire seabird colony, particularly those that nest on the ground,” said Vilikesa Masibalavu. “The information collected from the survey will be used to determine if these introduced
predators can be eradicated, which in addition to technical considerations requires the full support of the islands’ owners and communities, and the ability to prevent future reinvasion.” Local communities and landowners have already pledged their support for rat eradication, planning and discussions are now going on to establish how the eradication is to be carried out, and what restrictions on access, crab harvesting and other activities may need to be imposed until it is complete. The “operational plan” is expected to be finalised in early 2008. “Eradication will occur sometime between May and
August; the exact timing is dependent on many things, and ultimately comes down to the weather,” said Steve Cranwell of BirdLife Pacific. The Tui Laucala (chief or king of Laucula), whose jurisdiction includes the Ringgold Isles, said that the isles are the ancestral lands of his people, and home to ancient villages and burial grounds of great importance. “As guardians of the land, it is our responsibility to protect these islands. With the support of BirdLife International this is an opportunity for us to ensure the islands’ birds and other natural resources will be there for our ‘ira na gone’ (our children and their children).”

Network President Professor Ian Spellerberg says the top ten has now changed, with previous winners such as Pohutukawa and Cook’s scurvy grass nowhere to be seen. This year’s 10 most favourite plants included tawari, nikau palm, northern rata, kakabeak, coral broom, Poor Knights lily and the water brome. Over 100 species were voted for out of a flora of 2360 species.

UATARA on Matiu/Somes Island in Wellington Harbour are breeding, with two hatchlings emerging from eggs found on the island. The tuatara, hatched from eggs found on the island in May, were reared in captivity at Victoria University and were returned to the island sanctuary in November. They are the first known offspring of 54 Brothers Island tuatara transferred to Matiu/Somes nine years ago. The tuatara hatchlings have been named after the
two taniwha of Wellington Harbour, Ngake and Whataitai. Work by Forest & Bird volunteers continues to greatly enhance the environment for the tuatara and a range of other native species reintroduced to Matiu/Somes island. Last winter Forest & Bird members planted out 2450 plants at 10 sites on the island and another 1200 plants are being grown for planting out next year. More than two decades after the Forest & Bird Lower Hutt Branch began restoration work on Matiu/ Somes, native vegetation cover is now well advanced over much of the once barren island. Helen Bain

Operation Ark success four years on
O
PERATION Ark has been successful in protecting some of New Zealand’s most threatened species, according to Conservation Minister Chris Carter. Chris Carter, who has since become Education Minister, said that Operation Ark, launched four years ago to halt the dramatic decline of key native species in South Island beech forests, had been highly successful. The project aimed to bring the orange-fronted parakeet (kakariki) back from the brink of extinction, and to strengthen key populations of blue duck (whio), yellowhead (mohua) and long and short-tailed bats (pekapeka). Operation Ark pioneered the aerial use of 1080 specifically targeting rats, in tandem with intensive ground-based trapping of rats and stoats,
Orange-crowned parakeet
at key sites containing one or more of the target species. The project particularly targeted the increased numbers of predators that followed “mast years” of heavy seeding in beech forests. Among its successes have been the three-fold increase recorded in blue duck numbers in protected areas, increased mohua call counts in the Landsborough Valley, increased numbers of short-tailed bats in the Eglinton Valley and stablisation of populations of critically endangered orangefronted parakeets. However, the minister said many challenges still lay ahead. “While we can feel proud of what we have achieved over the past four years, the challenge to fully protect our most vulnerable native species over much larger areas remains.” Helen Bain
Fishing in a marine reserve brings a hefty fine
A
NORTH Shore man has been convicted after pleading guilty to illegally fishing in the Goat Island Marine Reserve near Leigh. Dennis Erskine was fined $1500 and his fishing gear was forfeited for fishing within the reserve and catching six snapper in March 2006. Department of Conservation investigator Richard Bray said the fine reflected the seriousness of the offence. “Marine reserves preserve all marine life in their natural state and taking fish alters this natural balance. No amount of
fines can bring those fish back but they can act as a deterrent.” Goat Island Marine Reserve was established in 1975 and is one of New Zealand’s most popular, visited by up to 300,000 people a year. While most visitors observe restrictions on taking marine life, there have been 15 prosecutions in the last nine years for illegally taking marine life from the reserve. Under the Marine Reserves Act people can be fined up to $10,000 or jailed for up to three months for illegally taking marine life. Helen Bain w w w. f o r e s t a n d b i r d . o r g . n z

chicks had been deliberately killed. “There were tracks everywhere made where a 4WD vehicle had driven right through the colony and backwards and forwards over the nests,” says Edith Smith. The dead birds had either been run over or hit as they struggled to take off. “It was particularly pitiful to see the injured adult birds which had made their way back to
their nests, covered up their live chicks, and then died,” she said. A Department of Conservation officer returned to the site with Edith Smith to assess the impact of the 4WD vehicle and found the birds’ injuries were consistent with vehicle strike. Not only was the incident an act of cruelty, but it was also a criminal offence. The black-billed gull or Buller’s gull is unique to
New Zealand. The species is already in serious decline and classified as Endangered on the IUCN (World Conservation Union) Red List of Species Threatened with Extinction. This is the same threat status as the yellow-eyed penguin, blue duck and Hector’s dolphin. Because black-billed gulls are protected under the Wildlife Act, Ashburton police are investigating the incident.

HE word ‘wilderness’ must be one of the most misunderstood in the English language. Most dictionaries define it in historically negative and anthropocentric terms – a fearful desert or barren place, uncultivated and uninhabited, a wasteland, or a garden grown wild. Positive concepts of wilderness as a place to experience spiritual, emotional and physical re-creation really only began to be expressed in the early 19th century.

But it was mainly New World explorers, writers, poets and philosophers who popularised the term, especially those voicing their concern as America’s primeval forests, prairies, and mountains were explored and opened up for settlement. Henry David Thoreau felt that ‘In wildness is the preservation of the world’, while Ralph Emerson believed that ‘In the woods we return to reason and faith.’ The preservation of America’s diminishing wilderness heritage became an allconsuming quest for generations of its visionary leaders – like President Theodore Roosevelt; John Muir, the founder of the Sierra Club; Aldo Leopold, Robert Marshall, and Gifford Pinchot, foresters of both preservationist and conservationist persuasion; and historians and educators like Roderick Nash. Just as the young American nation gave

the world the notion of national parks, the idea of legally protecting large areas of wilderness also had its origin in North America and culminated in the passing of its Wilderness Act in 1964. New Zealand’s concept of an individual wilderness experience and places called ‘wilderness areas’ largely stems from this American model. Indeed, it was exposure to the writings of Aldo Leopold and other wilderness advocates during a 1939 visit that stimulated Lance McCaskill to bring the idea of wilderness areas back to New Zealand national park circles. As a result, New Zealand’s vision of wilderness experience is similar to that of America’s – that wilderness is primarily a natural resource capable of being experienced first hand only through wilderness recreation. Of course, wilderness has intrinsic values which need no justification by way of human utility; likewise, it has enormous biodiversity and ecosystem values which defy being quantified in economic terms. But ultimately wilderness has to be experienced on its own terms, not locked away from humans as some type of scientific preserve. As Aldo Leopold concluded, ‘Wilderness areas are first of all a series of sanctuaries for the primitive arts of wilderness travel.’ There is a wonderfully rich wilderness
literature recording the feelings and experiences of those who have felt the urge to seek out wilderness. Their reasons vary, but most seem to involve personal growth through experiencing: • Solitude: that precious commodity so difficult to find in our frenetic urban society where we are constantly bombarded with noise and consumerism. Occasionally mankind needs ‘to be confronted with an alien, untamed world to be reminded that he is caretaker, not creator, of his universe.’ • Freedom: by travelling at will, simply, on nature’s terms, and having the freedom to make mistakes – and pay the price. Again, this sentiment has been eloquently expressed by Aldo Leopold: “Wilderness can give rewards and penalties for wise and foolish acts… against which civilization has built a thousand buffers.” • Romance: by standing on the threshold of unknown land, or venturing in the footsteps of pioneer explorers who left graphic diaries of their wilderness journeys – like William Colenso in the Ruahine Ranges, Charles Heaphy and Thomas Brunner in the Buller/West Coast region, Alphonse Barrington in the Olivine Country, and many others. w w w. f o r e s t a n d b i r d . o r g . n z

The Antipodes parakeet (Cyanoramphus unicolor) is endemic to the subantarctic Antipodes Islands, where its main habitat is the tall, dense tussocks and sedges. It is the largest of New Zealand’s parakeet species and nests in underground burrows.
• Challenge: by testing that deep human urge to gamble and probe the limits of our endurance. Admittedly, challenge is not unique to wilderness recreation, but wilderness survival does require the ability to handle major uncertainties such as unpredictable weather, route-finding, and difficult terrain. Overcoming the challenge of travelling through a hazardous natural environment can develop self-reliance and powerful bonds of friendship through shared skills and teamwork.
The large spotted black grouper (Epinephelus daemelii) can live for over 100 years, and is one of many marine species protected out to 12 nautical miles in the Kermadec Islands Marine Reserve.

In the words of Sir Edmund Hillary: “Nature needs time for growing and sleeping, free from automobile fumes and massive tractors, away from the cacophony of snowmobiles and trail bikes. There are plenty of tamed wonders for all to goggle at through vehicle windows – we must also retain our wilderness areas where nature can develop in its own calm way and where only those humans who are prepared to walk and sweat a little qualify to go.”

Found only at the northern tip of the North Island, Matapia geckos were probably once inhabitants of kauri forests. With that habitat almost gone from the Far North, the few known populations of these geckos persist in kanuka shrublands, creviced clay banks and island herbfields.

certainly separate species. The larger of these they called a “maxi-mac”, and the smaller a “mini-mac”. Soon, these two terms were being applied informally to larger and smaller ‘common geckos’ all over the country. In 1997 Dr Rod Hitchmough handed in a thesis that shook our understanding of the ‘common gecko’ to its very foundations. Extensive collections from throughout the country, analysed for genetic and morphological diversity, showed that even the most liberal of previous definitions for the ‘common gecko’ were seriously inadequate. No less than 11 species had been identified from within the 1980s ‘common gecko’, and a further four within H. pacificus. Hitchmough’s subsequent research has revealed another two from the H. pacificus group. So the recent discovery of the pygmy gecko brings us to a total of 18 species that, in 1955, would all have been classified as one. Moreover, these species are now attributable to at least
Godzilla meets Mothra: Different species of ‘common gecko’ have responded to nature’s pressures in different ways. Pygmy geckos responded by becoming so small that their predators cannot follow them into the narrow crevices where they live. But in the process they have limited the range of their own potential prey. The owlet moths relished by other ‘common geckos’ are well and truly off the pygmy’s menu.
three separate genera. All up, it is a potent lesson about how we should never take the common and ordinary for granted. It was Rod Hitchmough’s groundbreaking study that turned my own attention back to the ‘common gecko’. Contrary to a rather unfortunate but popular belief, these new species are not mere geographical varieties of one With some adults measuring just 38 mm in body length, the pygmy gecko of the Rangitata Gorge is the smallest of all New Zealand lizard species. It has many potential predators to look out for, including large ground spiders which can prey on juvenile pygmy geckos.

PYGMY gecko (mokomoko) has many potential enemies to look out for such as birds, skinks, centipedes and spiders. Being tiny, pygmies can survive by climbing into gaps so small that their predators cannot follow. These little creatures represent one extreme of adaptive radiation within the New Zealand gecko fauna, and are the most recently discovered member of the ‘common gecko’ group. When I was a child the “‘common gecko’” was the only species I was able to find. I yearned to find some of New Zealand’s more interesting varieties, such as the vivid-green Naultinus geckos, the yellow- or red-blotched forest geckos, the rare and handsome black-eyed gecko, and Stewart Island’s gaudy harlequin gecko. In contrast, the ‘common geckos’ were small and drab, they lived uninteresting lives in ordinary places, and the various books and articles always confirmed them to be, for want of a better word, boring! Now, having spent many years working with the brightest, boldest and rarest geckos New Zealand has to offer, an odd thing is happening. I find myself drawn irresistibly back to the ‘common gecko’. And now, older and wiser, I can see that they are a far cry from the drab and uninspiring little animal that I had been conditioned to think of them as. The story of the “‘common gecko’” goes back to 1955, at the time of the first major revision of the New Zealand lizard fauna. Charles McCann recognized just three species of brown-coloured gecko (genus Hoplodactylus), the forest gecko (H. granulatus) with its glossy orange mouth lining, the giant Duvaucel’s gecko (H. duvauceli), and, inclusive of population of small grey or brown gecko with a pink mouth, the ‘common gecko’ (H. pacificus). In 1977, Joan Robb and Rod Rowlands divided this ‘common gecko’ into two species, resurrecting H. maculatus from the history books and, in 1981, Robb also spun off two populations (H. chrysosireticus and H. stephensi) that had until then been treated as forms of the ‘common gecko’. From this point onwards the term “‘common gecko’” became restricted to just H. maculatus, the most widespread of all these species. At about the same time, Tony Whitaker and colleagues noticed that H. maculatus, as it was now being defined, occurred in two distinctive forms that were almost

animal, for they routinely co-exist. This is the benchmark proof of true species separation. And Hitchmough’s study has provided just the platform that was needed from which to start out with a fresh new look at the ‘common gecko’. For among these myriad species, a closer inspection has revealed a whole swathe of fascinating ecologies, physiologies and behaviours. For example, in 1994, Dr Alison Cree of Otago University found that korero geckos in eastern Otago underwent a significant reduction in reproductive output with increasing altitude. Rather than let the energy-starved highlands of Otago limit their distribution, the geckos can switch from an annual to a biennial reproductive mode as need be. Dr Mandy Tocher of the Department of Conservation (DOC) has

boundaries, regional council coastal plans and fisheries regulations. Tawharanui Marine Park was created by the Auckland Regional Authority (ARA), predecessor of the Auckland Regional Council (ARC), in 1981. The reason it was established was to protect marine life on part of the coast alongside Tawharanui Regional Park after a public access road was created. One of the first to explore Tawharanui’s underwater world was marine biologist Dr Roger Grace. He snorkelled the reefs around Flat Rock in the early 1970s and then later scuba dived there, mapping local underwater habitats. In those days both red and packhorse crayfish were often seen although the packhorse weren’t recorded after the early 1980s. Roger Grace began formal survey monitoring work in 1977 for the ARA, prior to the creation of the marine park. His surveys revealed smaller spiny rock lobsters or red crayfish, as they are known,

N the northern side of the Tawharanui Regional Park, little more than an hour north of Auckland, is an area of coast that has been protected for over 25 years. Known as Tawharanui Marine Park, the only real difference to a marine reserve is that it has been administered by the Auckland Regional Council and the Ministry of Fisheries. A change from marine park status to marine reserve status is now underway. Once public submissions have been answered the application will move on to the Director-General of Conservation and then the Minister of Conservation. Changing the marine park to a marine reserve makes good sense because of the length of time the area of coast has already been protected. It will also sort out the confusion that exists over the words “marine park”, as Tawharanui Marine Park is in the Hauraki Gulf Marine Park. The latter has no marine protection other than the existing marine reserves within its

at Tawharanui than at Mimiwhangata, north of Whangarei, another proposed marine park he was surveying. Partial protection was proposed for both parks with some recreational fishing and collecting allowed. At the time, it was thought limited fishing and collecting had no effect on the marine life. Despite this, Tawharanui Marine Park was designated a no-take protected area while Mimiwhangata Marine Park received only partial protection from fishing. Since then, although there have been some gaps between the surveys, red crayfish numbers have increased at Tawharanui while they have fallen at Mimiwhangata. By 2004-2005, when the last surveys were completed, the largest number of red crayfish was recorded within Tawharanui Marine Park. At Mimiwhangata virtually no red crayfish were recorded within the marine park’s boundaries, and were similar to numbers recorded along the adjacent unprotected coast. Those surveys concurred with anecdotal evidence of red crayfish numbers at Tawharanui. On some dives in the marine park in 2005 we saw dozens of large red crayfish amongst the sandstone reefs just offshore, although no packhorse crayfish. Recently we dived not far from the main beach at Tawharanui, descending to 10 metres below the surface. While exploring the low rocky reefs we again saw large numbers of red crayfish crammed into every available space. Some also wandered out in the open amongst the kelp holdfasts. Although we didn’t see as many as in 2005 they were still prolific. It is now unusual to see red crayfish in such large numbers on the north Auckland coast outside the Goat Island Marine Reserve, and even rarer to see them in the open during daylight. Around the deeper reefs, we witnessed more of the benefits of marine protection with almost every crack home to a few red crayfish from tiny prawn-sized critters to some over three kilos. The Ecklonia kelp swayed around, hiding them from view but exposed other marine life resident beneath its fronds. Sea anemones, yellow and orange golf ball sponges, grey finger sponges, colourful nudibranchs and a variety of sea shells were just part of the marine life there. During our dive we were accompanied by blue cod, porae and John dory. Schools of sweep and blue maomao swirled around us and nearer the bottom were replaced by Jack mackerel. For several minutes hundreds of thousands of these fish, sometimes known as yellowtail, swam past us towards an unknown destination over the sand flats.

the edge of the school, perhaps looking for a sick or slower fish to eat. The snapper schools, although not as large or numerous as at Goat Island, are still encouraging. Because of minimal fisheries surveillance and enforcement, there is still some poaching of the fish stocks within the park. Increased surveillance by the Department of Conservation under marine reserve regulations should eliminate this and snapper numbers will increase further. Tawharanui Peninsula has a series of sandy beaches bordered by steep hills and rocky reefs, typical of the Northland coast. Depending on the sea conditions visitor activities vary. When the long oceanic swells of late summer break on the beach, surfers dominate the water. On calmer days swimmers and snorkellers enjoy the marine life around the reefs. There is plenty for them to see as snapper, kahawai and trevally have moved in and established close to shore. The regional park has camping facilities which are almost on the beach and because of its popularity bookings are needed, especially over the busy summer season. Schools use the camping ground as an outdoor activity base and focus on the abundant marine life. Some also snorkel the rocky reefs on days when the swell allows. Larger fish, not often seen in shallow water, are beginning to reappear. Small schools of silver drummer feed over the kelp forests at the eastern end of the marine park and giant boarfish feed in the sand around the reefs off the main beach. Areas known as kina barrens where overgrazing turned them into barren rock, have begun to be replaced by beds of kelp. The increase in the predators of kina such as crayfish and snapper are responsible for this change. Outside the boundaries, rocky areas between low tide and six metres depth are still dominated by kina.

Without doubt the breeding stock of crayfish and snapper within the protected areas at Tawharanui and Goat Island contribute to the catches of fishers and divers outside the protected areas. Proposed boundary changes include ensuring that Cigar Reef, a popular fishing spot, is outside the boundary. In addition it allows everyone to see a couple of small pieces of coastline return to what the entire coast was once like. Currently the boundaries are marked with large orange and white triangles. Floats, marking crayfish pots of commercial fishermen based at Leigh, dot the outer boundaries. In spite of the narrow, unsealed access road to the regional park, visitor numbers have increased to around 160,000 annually. Tawharanui Regional Park is now a mainland island where introduced predators have been removed and a predator-proof fence established. Already the benefits are being felt with the return of bellbirds (korimako) to the area and the
reintroduction of kiwi, North Island robin (toutouwai) and whitehead (popokatea). Tracks through the regional park give amazing views out over the northern Hauraki Gulf. On a clear day the Coromandel Peninsula, Little and Great Barrier islands and the Hen and Chicken Island group are all clearly visible. Marine wildlife commonly seen in the area includes pods of common and bottlenose dolphins, Bryde’s whales and huge workups of Australasian gannets and other seabirds. What makes Tawharanui’s proposed marine reserve very different is the total protection it has had for over 25 years. Having a marine reserve next to the regional park makes sense, as Tawharanui is one of New Zealand’s special places where all New Zealanders can, and are encouraged to, visit.

Seabirds of Motu Tabu Christmas Island or Kiritimati in the Pacific Island nation of Kiribati has the highest species diversity and total seabird numbers of any oceanic island in the world, with up to six million present during the peak of the breeding season.

ROM a distance it looks like it’s raining seabirds as you approach Motu Tabu on the water. Then as you get closer to this tiny 3.5-hectare islet in the main lagoon at Christmas Island, you can pick out the many different species of tern, noddy, booby, frigatebird, petrel and shearwater as they fly over the atoll. Delicate white terns swirl around overhead and fly in close as you walk across the motu, keeping a watchful eye on human intruders. White terns and black noddies are the most abundant seabirds on the wing you’ll see here, but as you watch them you have to look carefully to avoid stepping on the thousands of ground-nesting seabirds also present at the peak of the breeding season. Seabird numbers here are monitored
by Kiribati Wildlife Conservation Unit rangers who have noticed a steady decline in several species in recent years, including phoenix petrels which have declined from about 20,000-25,000 in the 1980s. The threatened Polynesian storm-petrel is also believed to have experienced a similar decline in numbers. Polynesian rats (kimoa) have been living on Kiritimati’s main island for about 100 years, spreading more recently to some of the smaller lagoon islets. These rats are mainly a threat to smaller seabirds, but the arrival of the larger black rats means there is a newer and potentially more devastating menace now. Recent monitoring has shown that there are no rats on either Motu Tabu or the other main seabird islet, called Cook

Island. This has prompted the authorities to put into effect plans to remove these invasive pests from other islets of the Kiritimati atoll. Motu Tabu is a low-lying coral atoll of white sand and shell with varied vegetation including portulaca, scaevola, sesuvium, lepturus grass and salt bush. Christmas Island was formerly used by the British military as an atmospheric nuclear test site in the 1950s. The highest point is 13 metres above sea level with most of the rest of the atoll very low-lying, making it vulnerable to coastal inundation and sea level rise. It is one of the largest breeding refuges for the phoenix petrel, a medium-sized dark petrel with a distinctive white throat and underparts, and fast swooping flight. These petrels have a long breeding season with eggs, chicks, fledglings and juveniles seen here in September, in nests that are often just a scrape among shells, partly hidden under low vegetation. They forage offshore where they surface feed on squid, small fish and crustaceans. The Polynesian storm-petrel, which also nests on Motu Tabu in burrows of lepturus grass or sesuvium, is a globally threatened species classified as Vulnerable on the IUCN (World Conservation Union) Red List of Species Threatened with Extinction. Some of its largest colonies are found on Kiritimati. Like many other storm petrel species it forages offshore, flying just above the surface w w w. f o r e s t a n d b i r d . o r g . n z

of the water and dipping into the sea to feed on squid, crustaceans and small fish. Introduced rats and cats have reduced many of its breeding colonies in other parts of Polynesia, so much so that Kiritimati is now one of the last strongholds for this species. Competing for breeding space with these and other seabirds is the Christmas shearwater or te tinebu. This mediumsized dark shearwater has a distinctive rounded tail and breeds in burrows or under vegetation. They are common around Kiritimati, where they are usually seen foraging offshore in flocks for fish and squid. Like many of the other seabirds that breed here, the biggest threats to their survival are introduced rats, cats and pigs, poaching and destruction of nests. Sooty terns are abundant on Motu Tabu and other parts of Kiritimati such as Cook Island where thousands nest on the ground in dense colonies. Breeding numbers at Kiritimati have declined from about 25 million in the 1960s to 2-3 million now, with predation by rats and cats and poaching of eggs the main threats. Sooty terns forage offshore on surface fish by dipping and plunge-diving, and at night they take deep-sea fish that rise to the surface. The larger red-tailed tropicbirds – amokura to the Maori – are more abundant breeders on Kiritimati with many nesting under vegetation on Motu Tabu. They still occur in good numbers and are widespread throughout the Pacific, despite the threat of predation from rats, cats and pigs, and poaching by humans. They also forage offshore, plunge-diving for fish and squid. A few white-tailed tropicbirds also inhabit Motu Tabu, but unlike the redtailed tropicbirds, they always nest in a tree or at a cliff-site away from the ground. Three booby species nest on Motu Tabu: masked, brown and red-footed. The redfooted is the only booby species that nests off the ground, usually in a rough nest of sticks in low saltbush. Greater and lesser frigatebird species are present on Motu Tabu, both of which nest in low bushes on a large nest of sticks.

The male greater frigatebirds construct a nest and attempt to attract passing flying females by sitting in the nest and inflating their large red throat sac in a distinctive courtship display. In addition to the seabirds, several species of reptile occur here including green turtles, morning and stump-toed
geckos, and snake-eyed skinks. The invertebrate species include coconut crab, ghost crab, land crab and land hermit crab. Illegal poaching by local inhabitants is a significant threat to seabirds on Kiritimati as the human population increases with people relocated from other areas of Kiribati such as Tarawa.

HRISTMAS Island or Kiritimati (pronounced kritimati) is part of the Pacific Island nation of Kiribati (pronounced kiri-bas), located in the central Pacific Ocean. Kiribati comprises 33 atolls dispersed over 3.5 million square kilometres straddling the equator and located close to the International Date Line. Kiritimati is one of the Line Islands, a group of eight atolls and one reef, located about 3300-kilometres east of the capital, Tarawa, in the Gilbert Island group. At 642 square kilometres, Kiritimati has the greatest land area of any coral atoll in the world and is a globally important habitat for seabirds. Despite recent declines in local seabird populations, it still has the highest species diversity and total

About 5000 people live on Kiritimati. The poaching of eggs, chicks and adult seabirds has increased as people look for other natural food sources besides fish. Kiribati Wildlife Conservation Unit rangers are involved in protecting many of the islets from poachers. Recent reports of poaching include finds of the remains of many tropicbirds, boobies, frigatebirds, petrels, shearwaters and noddies on various islets. Poachers armed with machetes have also been caught in the act taking adult birds, as well as eggs and chicks. For those interested in visiting Kiritimati, there is a field guide in development by the Kiribati Wildlife Conservation Unit which is based in Kiritimati. It can be reached via airline flights between Fiji and Hawaii. Suzi Phillips chairs Forest & Bird’s Kaipara Branch and is a member of the national executive.

seabird population of any oceanic island in the world. Up to six million seabirds can be present on Kiritimati during the peak of the breeding season, including several million pairs of sooty terns. The atoll comprises a large, flat island, with a shallow tidal lagoon opening to the north-west. At the eastern end of the lagoon are many smaller, land-locked lakes. The total lagoon area covers around 160 square kilometres. A narrow reef platform extends up to 120 metres from the shoreline around the whole island. Eighteen species of seabird breed here, including the largest global population of two endangered species, phoenix petrel and Polynesian storm-petrel.

Naturalist-photographer Geoff Moon has spent much of his life capturing stunning images of New Zealand’s rarest and most secretive wetland birds such as bitterns and crakes. The protection of our remaining wetlands is more vital than ever, he tells Gordon Ell. Photographs by Geoff Moon.

EOFF Moon has spent three days setting up a birdwatching “hide” to photograph birds in a swamp near Motuoapa on Lake Taupo. So far his narrow angle of view through the lens of his camera has produced an Australasian harrier (kahu) swooping on the water taking — he thinks — tadpoles from the surface. Then comes the Australasian bittern (matuku), out of shot, but to his left and about to “boom”. To this time, no one has photographed this phenomenon, excepting possibly an old black-and-white movie film of the Eurasian bittern on the English Norfolk Broads. w w w. f o r e s t a n d b i r d . o r g . n z
The bird is not much more than a metre away but the New Zealand naturalist can’t take its photograph because it is beside his hiding place. The camera hole only faces forward, besides any attempt to shift the camera would be detected by the bird. Instead, very cautiously, he opens a minute peephole in the side of his tiny tent and sees the bird practically eye-to-eye. Its resemblance to a heavily built heron defines its place in the order of birds. The brown and cream streaked body usually disguises the bittern among the vertical leaves of raupo much as a tiger’s stripes camouflage it in an Indian rainforest. This bird, however, stands in a small clearing in the raupo just out of reach of the photographer’s lens. Suddenly it lowers its head. The photographer can hear it inhaling a great lungsful. Then it raises its head to the vertical, its body puffed up, and expels the air. The noise is like the sound of blowing across the open neck of a big bottle. ‘Booom’. In quick succession the bird dips and inhales again, then again booms forth. Four times. The frustrated photographer has at least observed this defining pattern of the bittern’s behaviour. From right alongside it doesn’t sound as loud as expected, but it obviously carries well. The distant sound

of a bittern booming is often the only clue to their presence in wetlands and damp country. “The boom is very much like the sound made by the kakapo ground parrot,” according to Geoff Moon. In both completely unrelated species, males establish territory and initiate mating behaviour by booming. While the boom of the kakapo is now restricted to remote offshore sanctuaries, the boom of the bittern can still be heard about many swamps on the mainland, particularly from the North to Manawatu and Wairarapa, and in Westland. “I think there are more bittern than people think,” says Geoff Moon. “People simply don’t see them.” Besides their secretive behaviour bitterns feed mainly at dawn and dusk, and also at night. They’ll stand still or crouch, neck stretched forward over the water for up to 10 minutes, before suddenly pouncing on their prey. They feed on small fish, eels, tadpoles, frogs, freshwater crayfish and aquatic insects. FOREST & BIRD • FEBRUARY 2008

The cryptic plumage of the bittern allows it to practically disappear when it “freezes” among its raupo habitat. Its cream and buff feathers turn to the vertical, as it lifts its neck and head, so it merges with the background of similarly coloured reeds. This is why some bittern species overseas are known as “tiger herons”.
“Bitterns are not easy birds to get close to,” says Geoff Moon, who uses a canvas hide, slowly moving it forward over several days, to approach the birds. He tells of using a colleague’s scrimsided hide once when the sun was low behind him. The moment he moved inside, the bittern saw his silhouette through the scrim and froze in its alarm position, neck and head stretched up so streaks of feathers on its body resembled the vertical raupo leaves behind it. Geoff Moon got particularly interested in the bird during the 1950s when he was photographing on glass plates in black and white. An Englishman whom he remembers as Mr Galey phoned him up from Atiamuri to say he’d found a nesting bittern on the edge of the river and built a hide to watch it: would Geoff like to photograph it? Thus began a season of Saturdays when the busy veterinarian left his home in Warkworth in lower Northland just after four in the morning and drove through the dawn to the south Waikato, some 300 kilometres away. Each week Mr Galey found more nests 26 FOREST & BIRD • FEBRUARY 2008
and set up new hides for him till he was studying five families of the bird. Galey had studied Eurasian bitterns in the English Norfolk Broads before coming to New Zealand to help build what is now the Atiamuri hydroelectric dam on the Waikato River. The river ran slowly then, below the looming bulk of Pohatu. “It was an amazing wetland along the river with a wealth of wetland birds, including ducks, New Zealand dabchicks, rails and crakes. Now it lies deep underwater as a storage lake for Whakamaru,” says Geoff Moon. “There’s still breeding habitat along its shores but not the wilderness of the old days.” The product of these trips are the elegant black-and-white pictures of bittern and some movie footage which Geoff Moon gathered while making scientific observations of these birds. “They’re solitary creatures. The female makes the nest — usually a flat platform in the raupo about 300mm above the water — and also sits on the eggs. The eggs are laid at intervals of one or two days and take about 25 days to hatch.” “During that time, she even has to leave
the nest to get her own food. The male has not been seen to do anything to help.” “Then of course she has to feed the chicks and she usually has four to feed.” “That can go on to some degree for a further seven weeks before they can fly. Often the youngest dies and only two or three survive to fledge.” “The female bittern gathers food for the nestlings and herself, first disgorging her last catch close to the nest so she can eat it later. The chicks are then fed on the nest in descending order of age, the eldest receiving the least-digested food while the youngest eats the most digested food.” ‘When the female leaves the nest her eggs, and chicks, are at great risk of predation. A major predator is the harrier hawk which cruises low over the reed beds looking for unguarded nests. Rats are another wetland predator, and possibly stoats though I’ve never seen them do this.” After about a fortnight the young bitterns start to wander about the reed beds close to the nest, though the mother still contributes the predigested diet. One of the problems bitterns have is the slime which spreads from the bodies of their favourite food, eels. These are not just elvers but eels up to round 30 or 40 centimetres in length. Sometimes bird and eel struggle for several minutes till the bittern can turn its prey headfirst into its gullet and swallow the still-wriggling eel down its long neck. Writhing to escape the beak of the bird, eels often tangle round its neck clotting the feathers with slime. To get rid of the mess, bitterns adopt the same tactic as other members of the heron family. From their lower chest they take powder down, rubbing head and neck against the soft feathers which crumble into a grey powder. This is wiped into the slimy mess and the feathers groomed. This preening can sometimes take hours. “While bitterns are susceptible to swamp drainage, I think there are more of them than estimated nationally,” says Geoff Moon. “For example, the excellent new Bird Atlas of New Zealand does record the bittern occurring around Lake Taupo but does not record it nesting. In fact, it lives in several of the swamps around the lake. “The reason it’s not in the Atlas is that no one has made a sufficiently scientific record from that area. Such scientific recording demands a count of nests to prove a breeding population.” “You can still hear the birds in swamps, w w w. f o r e s t a n d b i r d . o r g . n z

the bittern is a lot less common than the fernbird (matata), which is heard rather than seen among the rushes and scrub, they are nevertheless present in quite small wetlands as well as the classic swamps of Waikato, Northland and the West Coast of the South Island. Their unseen presence makes the protection of our remaining wetlands even more vital. Not only look out for it, frozen in the foliage. Listen and you may hear the male’s boom as its stakes out its secret territory.
Geoff Moon’s fascination with the life of the bittern began in the 1950s when his bird photography involved using black-andwhite glass plates. By the time he completed his life cycle of the bird he was using a 35mm camera, sometimes with a two-times extender on his 800 mm lens. Now digital cameras make extreme close ups much easier – Geoff Moon still uses slide film.
The globally threatened Australasian bittern occurs in New Zealand, southern Australia and New Caledonia and the Loyalty Islands, according to the Field Guide to the Birds of New Zealand by Barrie Heather and Hugh Robertson (Viking). It is classified as Vulnerable on the IUCN (World Conservation Union) Red List of Species Threatened with Extinction.

particularly around the southern shores in the extensive reed beds about Tokaanu. There’s simply not enough field recording of the birds here, and in many other parts of New Zealand, to be sure of its breeding distribution and numbers.” In fact, bittern have a widespread distribution through New Zealand, particularly in raupo swamps and rushes. Coastal dune lakes of the western North Island are a favoured place as is Westland. Bitterns can even tolerate brackish water though they keep away from the saltwater. What they need is dense cover where they can hide and hunt on the edges of water. “Bittern can also appear in wet paddocks where there is a little shelter and suitable food.” Perhaps a spring-fed creek or wet patch occurs in a paddock with sufficient cover for the birds to feed safely. Flax plantings and reeds along a little waterway may attract them.” Bitterns roost in trees with low trailing branches, such as willows over water. Their heavy-winged heron’s flight can sometimes be seen towards dusk as the birds fly out to feed in wet places. Their flight can be distinguished by observing the shape of the wings. While the flight is like that of a heron, the bittern has wings curved on the leading and trailing edges. Geoff Moon puts the bittern among other rarely seen birds of the wetlands. Because they feed at the change of light, and in the depths of the swamp, people simply don’t see them. The spotless crake and the marsh crake are two other such birds. While

Fool on the Hill The storm-swept tops of Stewart Island/Rakiura are the sole breeding grounds of the southern New Zealand dotterel. For years the Department of Conservation (DOC) has been controlling feral cats here after they nearly decimated the entire population, allowing dotterel numbers to increased from 62 to nearly 300. Kathy Ombler joined DOC Threatened Species Officer Phred Dobbins on a cattrapping expedition there.

HE flat, open tops are bleak places on Stewart Island/Rakiura. Subalpine bogs and battered shrubs — bent near parallel to the ground by raging gales – stunted manuka and tangled leatherwood clinging to the boggy ground form shadows in the constant cloudy murk and snow that falls, sometimes, even in summer. You might wonder why on earth a wading bird would fly so high to these forsaken places, never mind nest here and raise chicks. But when you stand on the tops, on a rare cloudless day and look down to the sandy shorelines and estuaries where the dotterels feed, it makes perfect sense. There are few high tide roosts close to the water. To the east is Paterson Inlet, where the high tide laps directly against dense podocarp forest. Further south, more dense forest meets the waterline of Port Pegasus. In the west, rolling sand dunes behind Mason Bay give way to the vast freshwater wetlands that almost cut Stewart Island in two and where, Phred Dobbins
The Gaelic name for Scotland’s mountain-breeding dotterel is “Fool o’ the tops”, because they were too trusting, and easy to catch. New Zealand’s dotterels have inherited the same name and, on Stewart Island, live in habitat that bears more than a passing resemblance to the tops of the Scottish Cairngorm Mountains.
wryly suggests, roosting birds would need snorkels to survive. So it is but a short flight, 550 metres straight up, from the feeding grounds to the open tops that provide a most suitable environment for roosting and nesting. Not so bleak after all, until feral cats arrived. We’ve boated to the head of Paterson Inlet and continued on the evening’s high tide into Freshwater River where we follow a forest-lined tidal channel to Freshwater Hut. We’re ready for an early start next morning to check the traps on Rocky Mountain, one of five above-bushline breeding areas DOC intensively manages, as in encircles with traps and 1080 bait stations during the dotterel breeding season. As he cuts up bait-size blue cod scraps into cat-tempting morsels for the traps on Rocky Mountain, Phred tells the story behind the dotterels’ recovery. In the early 1990s scientist John Dowding realised the dotterels were in serious trouble. He studied them on Table Hill, a major breeding ground to the south of Paterson Inlet, and found not only were there just a few birds remaining, but there was also a population imbalance. Most birds were female, there was just one breeding male in the area, and Dowding established that feral cats were to blame. The dotterel recovery programme began in 1992 on Table Hill, then the Rocky Mountain, where trapping is successfully protecting southern New Zealand dotterels.

breeding ground for around half the total population. Bait stations, over 200 in total, were placed at 50 metre intervals around the bush edge surrounding the nesting area, a broad, flat open mountain top of some 300-hectares. Every two weeks from September to January these were checked and re-baited. Getting to Table Hill involved nearly a full day of boating and climbing above the bush line, where there’s now a small hut for overnight shelter. The efforts immediately paid off, says Phred. Dotterels numbers increased and the breeding grounds and season expanded. “When I started the birds were still mainly on Table Hill, the Tin Range and above Port Pegasus. There used to be quite a punch up for space. Now anywhere there’s a broad mountain top above bush line you’ll find them, they also seem to have spread the breeding season. It’s almost as though they’re taking turns, you’ll only get two to three nesting at the same time.” “After a few years of working with the dotterels I’ve really come to appreciate wading birds. They are intriguing because they live in such extreme environments. Look at the distances godwits fly. They’ve got to have character.” The programme expanded in 1997 when four more areas were tagged for intensive cat-control: Mt Rakeahua, Rocky Mountain and two areas named somewhat ignominiously by their spot heights, 511 and 464. Access to each of these involves at least a one hour dingy ride through Paterson Inlet then a one to two hour climb to the tops. Extending efforts to more remote breeding areas has been considered but would prove more difficult, logistically, says Phred. “This is a low budget, long term project. To be effective long term we need to run it as lean as possible to make it sustainable. As it is, because we walk everywhere and we can only get in and out on high tide, it takes over a week to do the rounds, and we visit each area once a fortnight.” The extended breeding season from September to as late as February, depending on the weather, also extends the duration of the cat-control programme. Add it all up and after 14 years that’s a heck of a lot of climbs to the cloudy, wind-ravaged tops Phred and, for just the past few years, his one-man support team have clocked up. The track to Rocky Mountain, he announces as we set off from Freshwater Hut, goes something like a parabolic curve. I am warned. Fortunately the pace is slow. Phred is hunting as he goes; eyes and ears alert for cats or deer. When we do hear a rustle in the crown fern we find no animal w w w. f o r e s t a n d b i r d . o r g . n z

pest but a big, chubby tokoeka, a Stewart Island brown kiwi, out probing for food mid-morning and oblivious to the human presence nearby. At this stage of the trapping programme he’s only catching around eight or nine cats each season. “People ask if that’s enough to worry about but it only takes one cat to wipe out several pairs of dotterel.” When we break out above the bushline there’s a pleasant surprise. The cloud and wind that Phred says are his usual companions up here are absent. Snow had been forecast for our November trip, but instead we are greeted with calm overcast conditions and stunning views of Paterson Inlet, the Freshwater wetlands, Mason Bay and, to the south, Phred points to Table Hill and the other dotterel nesting areas now guarded by traps and bait stations. Being a touch higher, they are covered in murky cloud, and I thank Phred for selecting Rocky Mountain for this visit. The other areas, says Phred, have a definitive line between forest and open tops and the perimeter boundaries are lined with bait stations. Rocky Mountain is more complex, with several small clearings hidden between tangled subalpine shrublands and bogs. There’s also a public track to the forest line so traps are used where walkers might venture and bait stations, with their toxic 1080 baits, are placed around the more obscure clearings. When sitting on the nest, the parents take turns to go down to the estuaries to feed, Dad during the day and Mum at night. Once the chicks are hatched both parents stay with them, feeding on flies, moths, spiders and worms on the tops. There are usually three eggs so one parent each takes care of one chick and the third goes from one parent to the other, and doesn’t always survive, says Phred. When he comes across a dotterel nest, he knows exactly what behaviour to expect. “If you get to within 20 or 30 metres the female will run out of the nest, very low to the ground to lead you away. The closer the eggs are to hatching the more frantic she will be.” “I usually go very quickly to the nest to take a GPS reading, and if it’s within one week of hatching she’ll get really agitated,
dancing around with her wing out, pretending it’s broken and trying to lure me away.” After hatching, the chicks take around four weeks to fledge and stay with the adults a further two weeks after that. Phred knows of one current nest on Rocky Mountain and leads me to within 20 metres of a straggly, wind blown manuka bush on the edge of a clearing. A movement catches my eye as an adult dotterel scurries away across the clearing. We move a little closer and back she comes, one wing dragged along the ground. The three speckled eggs I glimpse in the nest beneath the bush are probably getting close to hatching. We leave “Mummy Dot” to settle and as we continue the trap circuit, Phred spies some soft, broken egg shell on the ground. He judges that it’s newly hatched, just a day or two ago and has blown out from the nest or been dropped by the adult and he’s pleasantly surprised. He didn’t know there was another nest up here, and it seems likely there’s just been another three little dotterels added to the growing population. Kathy Ombler is a Wellington-based writer.

HERE are two subspecies of New Zealand dotterel. The southern New Zealand dotterel is larger, heavier and more boldly coloured than the northern subspecies. Some authorities suspect the southern birds may turn out to belong to a separate species. Until the late 1800s, southern New Zealand dotterels were widespread throughout the South Island. As the ravages of introduced cats and mustelids, plus shooting for game and food took their toll, the birds became restricted to Stewart Island, with some wintering across Fouveaux Strait in Southland’s Awarua Bay. In 2006 a census count carried out at winter flock sites in Mason Bay, Port Pegasus and Awarua Bay found 270 birds. The current number is estimated to be nearly 300.

gathering, the waters here being well stocked with eels and waterfowl. A kilometre or so across from the road here you can walk onto a small moraine that overlooks the main lake to take in the impressive view of an outstanding oasis of red tussock and Carex (pükio) wetlands Plant species in the area include the threatened sedge Carex tenuiculmis and one of the largest populations of the threatened native lily Iphigenia novaezelandiae. Green hooded orchids bloom here on the moraine during spring and early summer, their hoods primed open ready to snap shut on the insects that pollinate them. You may be lucky enough to hear the deep booming “whamp” of a bittern emanating from the raupo where marsh crake creep through a forest of stems. Luckier still, you might see one or other of these shy birds as they stalk along the edge of the vegetation. The piping call of an oystercatcher flying overhead adds to the watery soundscape of Canada geese, black swans, New Zealand scaup, Australasian shoveller and pied stilt. Ten kilometres further up the valley brings you to Lake Heron, which is what is arguably the scenic jewel in the crown among these picturesque lakes. This name was given to the lake by the nineteenth century naturalist TH Potts because of the many white herons or kotuku that visited the wetland in his day, though sadly only very rarely now. Local Forest & Bird member and tour guide Warren Jowett comments that you’ll need to be very lucky indeed to see one because he has only seen a single kotuku here in 10 years of regularly visiting the lake. Lake Heron is a 625-hectare expanse of water fringed by red tussock and Carex wetland. The lake is a nationally significant stronghold of the threatened Australasian crested grebe and New Zealand scaup (papango), with Australasian shoveller, Paradise shelduck and black shag are also present on the lake. There is a car park on the southern side of the lake which can be reached via a short walk through a controversial stretch of road. A scenic walk from the car park area takes you up over to nearby Mt Sugarloaf which looks out over the lake and is a good place from which to watch for New Zealand falcon (karearea). There are also tramping routes from the car park area that take you up into the Taylor Range to the Clent Hills Saddle and Mt Taylor. The area adjacent to the southern end of the lake has views out over the lake to the Southern Alps and the surrounding hills and mountains. This makes for a suitable picnic lunch spot. There is also a public toilet by the car park.

“Canterbury” wrybill – the “huia” of the braided river.
Along the southern side of Lake Heron there is a complex of protected kettlehole wetlands where native broom, speargrass and green hooded orchids occur, one of which sits a few metres above the road. Tawny coloured skinks and orange tussock butterflies also lurk here among the tussocks. Turf vegetation, a rare habitat type, occurs around the kettleholes. Turf-forming plants that are found here include pygmy clubrush (Isolepis basilaris) and dwarf woodrush (Luzula celata), and the nationally endangered water brome (Amphibromus fluitans). The critically endangered Craspedia ‘Heron’ also occurs in the vicinity. At the head of the lake, overlooking an extensive area of wetland, is a closed gate where a track runs alongside the lower reaches of the Cameron River. This traverses an area of matagouri adjacent to the wide braided river bed. Banded dotterels and southern blackbacked gulls are abundant here, and at last count there were 28 very well camouflaged wrybills present during the breeding season.

Where and when to go
Wrybill are very hard to see among the greywacke stones. What can sometimes give them away is a movement or a glimpse of the dark black band on white breast as they feed alongside or even in the river, as they probe for insect larvae under stones. Peter Howden of the Forest & Bird Ashburton Branch found one when I visited last year. He called it a “Canterbury wrybill”. With its curved bill he said he likes to think of it as the “huia” of New Zealand’s braided river habitats. Small day moths with wings that glint iridescent purple-blue flutter around along the edge of the river bed and spotted skinks sometimes bask in the sun. At the end of my day trip in the area over summer, returning back along the road, I passed one of the small willowedged bays on the western side of Lake Heron. Pausing here I saw five crested grebes in close formation glide into view close to shore. It was a moment of Zen-like tranquility as they dived underwater, one after the other, making a memorable ending to the day.

HE settlement of Hakatere is a gateway into the Lake Heron sector of the new Hakatere Conservation Park via the South Branch of the Ashburton River. Hakatere is a two hour drive from Christchuch. Take State Highways 78 and 72 south to Mt Somers and turn inland towards the Ashburton Gorge and Hakatere itself. At Hakatere turn right towards Maori Lakes and Lake Heron. Stop three kilometres along this mainly unsealed road and park to the side where a short track runs off to the right to the open braids of the Ashburton River below Clent Hills. You can continue on along this same road to Maori Lakes which is approximately two kilometres from the river stop. Lake Heron is a further ten kilometres along the same road from Maori Lakes. The road continues on approximately five kilometres from Lake Heron to the Cameron River and ends at the top end of the lake. 4WD vehicles have caused damage to vegetation around Lake Heron, so vehicle owners are asked to remain on marked roads at all times. Nesting birds such as banded dotterels breed in the vicinity of the road and walking tracks in the area so care should be taken not to drive over or trample nests containing eggs or chicks. Being close to the Southern Alps and the West Coast means the weather in the area can vary from wintery cold blasts bringing snow from the west to sweltering summer heat, so it pays to check the forecast before a visit and to be prepared with suitable clothing and outdoors gear. The best time to see alpine flowers is through spring and summer. Migratory birds such as wrybill, black-fronted tern, black-billed gull, banded dotterel and South Island pied oystercatcher are only present during the spring and summer w w w. f o r e s t a n d b i r d . o r g . n z

Lakes Emma and Roundabout are both a short walk from the road. Lakes Clearwater and Camp are right next to the road. A longer walk which starts a kilometre west of Hakatere itself runs five kilometres south-west towards Lake Emma and continues on four kilometres along the south side of the lake, past a hut, and adjacent to an extensive wetland west of the lake. The track then rises up Balmacaan Stream to Balmacaan Saddle a further four kilometres where a second hut is located.

Itinerant Ecologist – Geoff Park
Teeming with birds, still
E
COLOGY, in essence, is about interactivity. The betweenness and inbetweenness of life. It views the life of the world less as a myriad of species than as myriad interacting systems, some fragile, others resilient, but each alive in their own manner. Seemingly chaotic in the process, but measurable and predictable too. If they’re fortunate, ecologists first learn this not from books or lecturers, but direct from nature, in their criss-crossing of wild landscapes tracking the reach and spread of plants, and in the following of birds through space and season. In my case, it was in the company of botanists, surveying vegetation and discovering how plants distribute themselves along environmental gradients: fertility, temperature, moisture and so on. Birds were background noise. It was an ecological learning curve that soon had me too little in wild forests, and too much in laboratories determining what my leaf and litter sampling revealed of their nutrient budgets. But it coincided with the 1970s campaigns to stop the government felling the last lowland forests, and the need for new, young ecologists to conjure up the science as to which most needed reserving. Not least, how native birds behaved in landscapes that still had some lowland
34
forests standing. Were some forest habitats more important than others? And where were they? In 1974, the Government’s scientific agency, DSIR, located a team of ecologists to the South Island’s West Coast to seek answers. By the time I joined them in a Western Paparoa fingervalley, the Ohikanui, early in 1975, their ornithologists had come up with a way in which different people could measure the relative abundance of bird species in different environments, and do so with statistical accuracy. Within a year of careful, replicated listening, the “five-minute bird count” was revealing firm evidence that some birds moved vast distances seasonally, and huge disparities in bird abundances in different kinds of forest. Confirming, with measurement, what so fascinated early European observers of New Zealand birdlife in the years when huge swathes of coastal country were still forestdown-to-the sea: the striking difference, said Dumont D’Urville in 1827, between the hill forests’ “funereal silence” and the flat coastal lowlands “so full of life”. Coastal lowland environments, with their relative warmth, frost-freeness and fertility, seemed to abound with birds compared to inland, upland environments.
As telemetric tracking of kereru would later show, some flew many miles in search of a meal, often completely vacating inland valleys in winter. Five-minute bird counting began putting figures on what some ornithologists had suspected all through the twentieth century, but had never ventured to measure. Consequent on New Zealand’s pastoral settlement the century before, “lowland forest areas which had distinctive advantages for some birds not possessed by hill country and mountain forests, disappeared almost completely”. The result of which, said Robert Falla, was that “birds deprived of lowland forest into which they were accustomed to descend in winter have become extinct or very scarce”. The Western Paparoas were, by the 1970s, one of the last parts of New Zealand in which something of the forest continuum from the lowlands to the mountains still survived. In winter, the bird-counting revealed, the coastal lowlands – including a basin of ancient woods around the now-infamous Cave Creek which the government’s foresters had begun logging – were busier with birds than any other area in mainland New Zealand. Only one other place in the country, at that time, revealed greater winter numbers:
to tree, rising in flocks of half a hundred or so, with a whirring of wings …” A nineteenth century New Zealand whose lingering on into the twentieth century I just caught in the memory of one of the last white-pine bushmen – of walking to work beneath trees that moved with kereru. A quest which, before all that though, had taken me to the offshore island forests in which the highest present-day birdcounts of all had been made. Hitching as botanical support to a Wildlife Service appraisal of Little Barrier Island’s petrel populations, just before the elimination of cats. A tasting, never forgotten, of the New Zealand bush minus mustelids. And rodents, other than kiore. It was late-November, flax’s flowering finishing and pohutukawa’s just beginning. From the crack of dawn to dark, a cacophony of birdsong and wing-beating that didn’t let up from when we first heard it from way offshore to when we were revved away from Te Maraeroa’s surf. Bush-fit from the Paparoas, we roamed up into Herekohu’s cloud forest and down along ridges of old kauri survivors of the quick plundering that Hauturu underwent prior to its preserving, into valleys whose forests seemed more tropical than temperate. Only on the driest, boniest ridges did the cacophony diminish. Hauturu is more than a pre-eminent place in the preserving of New Zealand’s indigenous biodiversity. It was one of the places where it was first mooted – and, eventually, achieved. Which is what, half a lifetime later, had me back there earlier this summer, on the trails of the people who got Little Barrier Island Sanctuary happening. One, Andreas Reischek, the 1880s collector
Sara McIntyre
the island sanctuary, Little Barrier, Hauturu. The consequence of seeing my plant ecology assist such avian discoveries was that birds became other than background noise. They began to shape how I read the landscape. Not least kereru, the great disperser of forest trees. I learned, for example, the profound pleasure of being able to synthesise what I’d learned about trees and their ecology, soil fertility and fecundity, geomorphology and local seasonality, and predict the places in which I’d see kereru. Then hearing the whoop of their wing beats. The Paparoa evidence begged the question what the forests of warmer, northern coasts must have been like, in bird terms, and what still might survive. The high winter bird-counts of the Punakaiki Coast in particular, with its still-forested limestone country, proved significant in the establishment of Paparoa National Park. In area it is tiny, but its sheer birdiness, relative to the surrounding uplands, was proof that lowland forest was something that no district that still had some should lose. It ignited a quest as historical as ecological that revealed a land of wild woods and birds underlying the pasture and suburbs of the New Zealand we inhabit. It took me to 1820s ‘Bay of Islands’ river country of “immense trees… extending to the very edge of the water” …of “birds, so numerous at times as to almost darken the air…” through which the artist Augustus Earle was paddled. To a Horowhenua plain still like it in the 1870s: “tall timber to the water’s edge … pigeons … circling and wheeling in the sunshine … literally in thousands, drifting from tree
w w w. f o r e s t a n d b i r d . o r g . n z
of bird-skins, who, curiously, notwithstanding the 150 stitchbirds (hihi) he shot, was behind the original sanctuary proposal by the Auckland Institute. Another, Henry Wright, whose 1892 visit, and to-the-point report to the Premier advocating Hauturu over Resolution Island, led to it being prised from its Ngati Wai owners, the halting of kauri felling, and a caretaker “whose first care should be the extermination of the cats”. Henry Wright had a multi-tasker’s vision for Hauturu. As well as precious bird sanctuary, he imagined it becoming “the show place of the North Island, to which steamers from Auckland will ply with excursionists to see not only the last of the native birds, but the remaining specimens of the noble kauri, the nikau palms … still flourishing in all their pristine loveliness, when the primæval forest elsewhere will have long since passed away”. Fortunately, things didn’t go that way. Nor did the “experimenting upon the culture of extra-tropical utilitarian plants”, like tea, coffee and teak trees, that Wright proposed for the fertile Te Maraeroa Flat. Today, in early summer, the Flat is prime kereru habitat. There’s plenty of food in the surrounding puriri, taraire and nikau regrowth, but Hauturu’s kereru obviously prefer the lush meadows of pohuehue, Muehlenbeckia, and calystegia winding their wiry way among English grasses and clover from the old Ngati Wai cow pastures. In which cats no longer lie in wait. Te Maraeroa Flat at this time of year must carry hundreds and hundreds of kereru. Most of them, for most of the time, out of sight in the high grass, the only clue to their presence being the number looking on from adjacent trees, and dropping down to join in. Then as we near, just as I’d read about from the-century-before-last, but thought I’d only imagine: “rising in flocks of half a hundred or so, with a whirring of wings”. As they do, the sudden realisation that, while we in “ordinary” New Zealand rarely see the prospect, kereru will, when it can, be the flock bird it is by nature. Birds able, when they choose, to be on the ground once more. I see it again, high up in the repairing kauri forest after the next day’s rain, watching the saddlebacks I’ve seen coming off second-best to the tui in the quest for pohutukawa nectar, spending most of their time flicking apart freshly-moistened leaf litter. No sense of how lucky they are. All this island re-jigged ecologically for them to live in as they’re evolved to live. As they, and kereru, could again in the stretches of country we’ve been learning to de-cat, de-rat and de-weasel.

The secret world of wetlands There is still time to restore New Zealand’s watery world of wetlands, from the mountains to the sea. Words by Ann Graeme. Illustrations by Pamela Robinson
N
EW Zealand has a wealth of wetland habitats from the coast to the high country, which includes mangrove forests, salt marshes, raupo swamps, peat bogs, dune lakes and mountain tarns. They all have one thing in common; they are wet, and their wetness shapes their unique plant and animal communities. For most plants, wetlands are places to drown their roots in. Roots need water but they need oxygen too. There is little room for air in sodden soil, and what oxygen there is in the water is largely used by soil bacteria. Only specially adapted plants have found ways of breathing in such difficult circumstances. One strategy is to grow roots up into the air instead of down into the waterlogged soil. Every mangrove tree is surrounded by a sunburst of peg-like breathing roots. They grow up out of the proper roots which radiate from the tree trunk, just beneath the mud. In shallow freshwater, swamp maire or maire tawake grows bunched fingers of spiky breathing roots and those of pukatea arch out of the water in hoops. Both it and kahikatea have buttress roots to support them in the yielding mud and to provide extra air space for gases to circulate. These trees grow in shallow water. Deeper water is the domain of raupo and rushes like oioi (the golden jointed rush), sea rush, jointed twig-rush and the giant wire rush. Their pipe-like stems are the snorkels for their roots. The stems are either hollow or are packed with spongy cells which allow air to diffuse directly to the roots.
36
Breathing is only one of the problems facing plants that grow in wetlands. Getting seedlings to take root in water is another. The mangrove seed is as big as a broad bean and it germinates on the parent plant. When it falls into the tide, the seedling root is ready and able to anchor the embryo plant and the little shoot is raring to grow where ever the tide casts it up. You often see hundreds of these ‘seeds’ stranded at high tide along northern coastlines. Rushes and raupo have tiny seeds and only a few manage to germinate and grow. But when one establishes a beachhead in the wetland, it sends out underground rhizomes so that in no time the pioneer plant becomes a clump and then the clump becomes a forest of waving stems. Some plants can only live in wetlands. Not for them the jostle of species that struggle for space in higher, drier, easier conditions. The upside of growing in a wetland is reduced competition – to a considerable extent, the wetland plants have it all to themselves. Around the margins of the wetlands grow fellow travellers, plants which like it damp but can’t tolerate too much water. Flax, manuka, cabbage trees, toetoe, Coprosma propinqua and a variety of sedges and grasses favour the wetland margins although they can, and do, grow elsewhere. Like a picture, they frame the swathe of plants that paddle in deeper water, together creating unique communities which support a myriad of native birds, fish and insects. Most wetlands are shaped like saucers but the raised peat wetlands are the reverse. The Kopuatai peat dome and the four domes within the Whangamarino wetland bulge upwards, (though so gradually that
you would scarcely notice). This bulging has come about because the centres of their vast and shallow basins were fed, not by the sediment-rich water flowing off the hills, but by rainwater. Dead vegetation scarcely rots in pure water so it has built up, layer upon layer, year upon year, to form spongy peat. Given time – a long, long time – such peat will become coal. In recent times, the same wetness that led to the evolution of wetland communities has led to their destruction. Wetlands are of gentle contour. Filled with sediment eroded from the hills, they are often very fertile. Compared to the forested hills, wetlands were easy to drain and turn into top class farmland. Throughout the country, drains and stopbanks remind us of vanished salt marshes and swamps. The tracery of man-made canals dissecting the plains of Waikato, Hauraki, Rangitikei, Horowhenua and Southland maintain pasture where once grew endless flax swamp and kahikatea forest. Cattle browse where water birds once waded. And it’s not only farmland we have made out of wetlands. Towns sprang up, built on the swamps and salt marshes around our ports and river mouths. The city of Christchurch is built on wetlands that once surrounded the Avon River. Now only the Travis wetland remains, long neglected and weed infested but still home to half of Christchurch’s pukeko population along with 30 other native bird species, 600 insect species (of which 83% are endemic) and the endangered Canterbury mudfish. Now the wetland is being restored and North Canterbury Forest & Bird members have planted a new generation of kahikatea which shelter beneath the grey willow which they will one day supplant. Protected and cared for, Travis wetland is lucky. But even care may not be enough to save a wetland. You can fence the cattle out but you can’t fence the water in, as
Neil Hayes in the Wairarapa is finding out. Nearby water extraction for dairy farm irrigation threatens to lower the water table and dry out his QEII wetland reserve. Until quite recently, wetlands have been the Cinderellas of our native ecosystems. Forests are easier to appreciate. Firm under foot, we can walk and tramp and find adventure amongst tall trees. We can revel in their beauty. But wetlands are different. They are mucky and scrubby and give us wet feet and scratches. You can’t see into them or get into them so easily. And to some people they’ve been seen as “wasteland” and used as rubbish dumps. In the last century and a half, the vast majority of New Zealand’s wetlands have been drained or irretrievably modified. Once, wetlands covered nearly 700,000-hectares (ha). Now less than 80,000-ha remain and many wetlands are polluted by run-off from farms and factories, grazed by cattle, invaded by weeds or starved of water by surrounding drains. The smallest wetlands are most at risk – and most remaining wetlands are small, many less than a hectare in extent. Wetlands used to be important carbon sinks, and they still are, but their potential has dwindled with every wetland drained. Ironically only the mangroves, expanding and flourishing in response to the warming climate, are increasing their carbon uptake and could provide a new carbon sink – if we let them. But despite all the stick we have given our wetlands, those that are left keep on working. They mitigate floods by soaking up heavy
rainfall and settle sediment out of dirty water. They take up nutrients and cleanse water passing through them. They buffer the land from the water, a check for erosion and a filter for sediment. So useful are they that we now recreate wetlands to filter our stormwater and to treat our sewage. Wetlands are better understood and appreciated, and their loss is slowing these days – though it hasn’t yet stopped. We have so little wetland left, we can’t afford to lose any more. The big wetlands are important but so too are the mosaic of little wetland remnants. Even poor, pugged, weed-infested wetlands could still be restored to health and vitality. Let us treasure our wet places. They may be shy, hiding behind impenetrable and scratchy thickets and gumboot-stealing mud, but they are a world in miniature. Enjoy the bold pukeko, watch out for the secretive banded rail (moho pereru) or shy brown teal (pateke) and listen for the elusive fernbird (matata) that calls like a ventriloquist somewhere close by. Savour the fragrance of mangrove and marsh ribbonwood flowers and step lightly in the yellow carpet of Batchelor’s buttons. These are unique communities of wetland birds and plants, and they are only found here in New Zealand. Acknowledgements: The State of New Zealand’s Environment, Ministry for the Environment, 1997.

No. 149 FEBRUARY 08
THE huge number of public submissions made on the draft Threat Management Plan for Hector’s and Maui’s dolphins has been blamed for the plan being delayed. Originally expected by December 2007, the plan was now not expected till March, according to Fisheries Minister Jim Anderton and Conservation Minister Steve Chadwick. The ministers blamed the delay on the large number of public submissions – 2475 – and the need to take time to carefully consider them. Jim Anderton also decided not to introduce interim protection measures over summer because he said a number of protection measures were already in place. However, Forest & Bird Conservation Advocate Kirstie Knowles said the longer the delay in introducing the Threat Management Plan, the longer the endangered dolphins

▲ Hector’s dolphins off Banks Peninsula. remained at risk, particularly from the threat of set nets, which are most widely used by recreational fishers over summer. “With just 111 Maui’s dolphins remaining, any further deaths will push the species even closer towards extinction. We urge the ministers to act with urgency to put in place effective protection measures that will
ensure that we stop human-induced deaths of Hector’s and Maui’s dolphins before it is too late.” Forest & Bird has sought a nationwide ban on set nets, which are the most serious threat to the dolphins, and marine mammal sanctuaries to protect Hector’s and Maui’s dolphins in key areas.
THE Government has issued proposed new standards to reduce the number of seabirds killed as bycatch in New Zealand commercial fisheries. Fisheries Minister Jim Anderton said the best available information suggested that about 5500 birds were killed in trawl and longline fisheries in 2004 – the scientific model used suggests the number could have been as low as 2500 or as high as 7500. The Minister said albatrosses and petrels were slow breeders and many of their populations could not withstand many extra deaths. Forest & Bird has called for tougher regulations on bycatch deaths following incidents in which large numbers of seabirds were killed, including when a longline vessel fishing on the Chatham Rise caught 12 critically endangered Chatham albatrosses and 22 Salvin’s albatrosses 38 FOREST & BIRD • FEBRUARY 2008

▲ Antipodean wandering albatross, displaying, Antipodes Island last September, and over 50 Antipodean wandering albatrosses were caught by a single longline vessel fishing for swordfish off the Kermadec Islands. The draft standards propose setting a bycatch limit of somewhere between 500 and 2000 birds, and outline proposals for
monitoring this. However, if the limit is exceeded it will not automatically close the fisheries, but would prompt further action and regulation. Submissions on the proposed standards closed on February 1 and the final bycatch limit will be set by the minister later this year. w w w. f o r e s t a n d b i r d . o r g . n z

GREENPEACE will be spreading the ecologically sustainable fisheries message with the help of Forest & Bird’s Best Fish Guide. As part of its campaign to promote ecologically sustainable management of New Zealand’s commercial fisheries, Greenpeace will be distributing the Best Fish Guide to its members and encouraging them to support more ecologically sustainable fisheries. Forest & Bird branches are distributing the Best Fish Guide wallet card in communities around New Zealand, making it available in schools, supermarkets, cafes, restaurants, fish and chip shops, recreational fishing supply stores, public libraries and community centres. Copies have also been sent to Forest & Bird members overseas and environment and conservation groups promoting the sustainability message in Europe, North America and Australia. Forest & Bird Conservation Advocate Kirstie Knowles says previous editions of the Best Fish Guide have been distributed to hundreds of thousands of people in New Zealand and overseas, and it is hoped that the updated version will reach many more. “The more people that are able to use the Best Fish Guide when they purchase seafood, the more we can do to help make our fisheries more ecologically sustainable. If everyone can do their bit by making the right choices for our oceans when they buy seafood, we can make progress towards truly sustainable fisheries.” Fisheries Minister Jim Anderton has criticised the Best Fish Guide as “simplistic” but Kirstie Knowles says the facts on New Zealand’s fisheries speak for themselves:

A highlight of the bus tour was a visit to Margaret Mahy’s house in Lyttelton, where the famous author willingly submitted to an “energy audit” of her home to identify where she could further reduce her household energy consumption and carbon footprint. Forest & Bird General Manager Mike Britton says the Be the Change campaign is a positive way of showing New Zealanders how we can all make a difference through our own everyday actions to help stop climate change. “Climate change is probably the most critical conservation issue we are facing, and if we want to find solutions to climate change, we all need to act now. It’s no use just waiting for governments around the world to do something about the problem – if we all take responsibility in our own lives, we can have a greater impact.”

Sea lion kill quota still too high
▲ New Zealand sea lion, Snares Island – up to 81 can be killed this year in the southern squid fishery.
FISHERIES Minister Jim Anderton has set the kill quota for New Zealand sea lions in the southern squid fishery at 81 for this season. This means the fishery, which opened in December, can kill up to 81 of the endangered marine mammals in its trawl nets before the fishery is closed. The limit of 81 is lower than the 93 limit set for the 2007 fishing season, but Forest & Bird Conservation Advocate Kirstie Knowles says it is still far too high and poses a threat to the declining population of endemic sea lions. Once common right around New Zealand’s coastline, New Zealand sea lions now breed only at subantarctic Campbell and Auckland Islands and on the Otago Peninsula, and have a total adult breeding population of just 5000 animals. Forest & Bird has called on the Government to reduce the sea lion kill quota to near zero – a move backed by more than 20,000 people who signed the Save Our Sealions petition in 2006. The Department of Conservation has put forward draft population and species management plans which aim to guide DOC in its management of New Zealand sea lions over the next 10 years, and outline options for managing the extent of sea lion deaths in fisheries. Public submissions on the draft plans closed at the end of 2007 and final plans are expected to be introduced later this year.
Gowan protection a win for water conservation AN Environment Court decision in August confirming that the Gowan River should be protected from inappropriate hydroelectric power development is an important win for the river and for New Zealanders. The Majac Trust sought to vary the Buller Water Conservation Order to allow water diversion and discharges necessary to develop a hydroelectric power development on the Gowan, a tributary of the Buller River. Forest & Bird, Fish and Game, the Department of Conservation, rafting companies and many individual submitters opposed the original application, which was rejected by a special tribunal in 2006. The case then went to the Environment Court, where the same groups again opposed the application at hearings in Nelson in early 2007. The Environment Court now made the same decision as the tribunal and recommended against varying the Water Conservation Order. Forest & Bird lawyer Marion Yoder says the case was significant because it was the first time anyone had applied to vary a Water Conservation Order. “Forest & Bird is delighted that the Environment Court has agreed with the tribunal, not only for conservation of the Gowan, but because it is a precedent that makes it clear that a Water Conservation Order is not to be taken lightly.” Water Conservation Orders recognise outstanding characteristics of waterways, including recreational, environmental, cultural and scenic values. Activities which may compromise those values, for example by changing water flows or adversely affecting water quality, are closely scrutinised when protected in this way. The Gowan is protected under the 2001 Buller Water Conservation Order, which recognises the value of the native eel and introduced trout fishery, blue duck habitat, kayaking and rafting opportunities and the wild and scenic nature of the Buller and its tributaries. 40 FOREST & BIRD • FEBRUARY 2008

▲ This albatross chick starved to death after being fed discarded plastic cigarette lighters by its parents after they ate them, mistaking them for food.
DISCARDED fishing nets and plastic debris are killing marine wildlife around the world, so Forest & Bird is urging people not to discard these items at beaches or from boats this summer. Leaving plastic rubbish such as bottle tops, plastic bags and plastic lighters on beaches can lead to seabirds such as penguins and albatrosses, and marine mammals such as dolphins and seals, eating them and then choking or starving to death. Discarded plastic packaging straps can cause marine wildlife such as penguins and seals to become entangled and die, and discarded fishing nets and line can also kill marine mammals and seabirds. “Plastic rubbish left at the beach can remain in the environment for hundreds of years, so it is important for people to take their rubbish home. This includes refraining from dumping rubbish off boats and leaving pieces of fishing net lying around,” says Forest & Bird Advocacy Manager Kevin Hackwell. The problem is so severe in the North Pacific that there is a swirling mass of over a million kilos of plastic and other debris now covering an area of ocean the size of Australia which lies between the Hawaiian Islands and Alaska, according to researchers with the Algalita Marine Research Foundation.

Ghost nets and plastic debris killing marine wildlife
Foraging albatrosses can mistake plastic debris items floating on the surface for food items and fill their growing chicks with them. These include cigarette lighters, toothbrushes, syringes, clothes pegs and small toys. On Midway Island alone 40% of albatross chicks die from swallowing plastic debris which fills their stomachs causing them to starve or choke to death.

Forest & Bird joins Wairau River consent appeals THE Department of Conservation (DOC) and Fish and Game have both lodged appeals with the Environment Court on resource consents granted to TrustPower by Marlborough District Council-appointed Commissioners to build a hydroelectric power scheme that will cause environmental damage to the Wairau River. Forest & Bird has joined the appeals under section 274 of the Resource Management Act. However, a further hearing on proposed conditions was held on 21 January with a final decision from the Commissioners now due. This has meant that the appeal process has been put on hold while awaiting the final decision from the Commissioners. DOC has been conducting surveys of breeding birds, particularly black-fronted terns (tarapiroe) on the river over the spring/summer nesting period with the results due to be published shortly.

It is amazing to explain an issue and have the children come up with their own answers to a real-life conservation dilemma.” Helen Bain
WO Auckland schools’ environmental efforts have been awarded Green Schools Awards by Forest & Bird’s Central Auckland Branch. Glendowie Primary School won its award for cleaning up a stream bordering the school, while Wesley Primary School was awarded for setting up a school recycling scheme. Central Auckland Branch Chairwoman Anne Fenn says the commitment of the students involved was really impressive. “Today’s children will become the next generation of community leaders, ratepayers and citizens, so it is really important that they learn to understand and respect the environment. Green Schools Awards hope to encourage young people to learn about and care for the environment around them.” In both cases the schools will use their $500 prize money to develop their environmental projects further.

Kapiti Mana Branch restoration projects
E
IGHTY-five years after Forest & Bird’s genesis on Kapiti Island, Forest & Bird’s Kapiti Mana Branch is in good heart continuing the vision – and hard work – of the organisation’s founder. Visiting Kapiti Island after returning from the First World War, Captain Val Sanderson found the forest playground of his youth bereft of birds and overrun by grazing animals. It was the success of his campaign to restore Kapiti to its former glory that led to the formation of the Native Bird Protection Society – later Forest & Bird – in March 1923. More than eight decades later, the Kapiti Mana Branch is just as committed to preserving Kapiti’s environment and native species – and its work has left its mark throughout the district. Branch Chairman David Gregorie and Secretary John McLachlan show me what John calls the “pocket handkerchief ” of bush at Queen Elizabeth Park which triggered the resurgence

in activity by branch members 20 years ago. Branch member June Rowland was the “leading light” here in instigating the replanting of native species around the small remaining stand of mature kahikatea that was besieged by salt winds, pests and “a sea of blackberry”. Two decades later the forest and surrounding dunes and ephemeral wetlands are cloaked with tall ngaio, mahoe, cabbage trees, flax, native fuchsia and kanuka – plants grow amazingly fast in Kapiti’s warm climate. This success spurred the branch on to even more ambitious projects. Further north the 6.8-hectare Kaitawa Reserve was set aside as reserve when the surrounding area was subdivided for housing 30 years ago, but in the 1990s Kapiti Coast District Council proposed selling it. Forest & Bird member Molly Neill stepped in, and the branch has been steadily planting natives and clearing weeds every

My thanks go to all our dedicated members whose support makes possible all the conservation work that Forest & Bird does– your contribution is truly appreciated and makes a real difference to the important conservation goals that we all want to see achieved. We also launched a new promotion of our Sustain membership in December,
which is a programme for monthly giving. The response to that promotion so far has been very encouraging and I would like to thank those who have already responded. While the support we receive from members and donors is enormously valuable, we do encourage everyone who is in a position to consider becoming a Sustain member to do so. By doing so you will be helping to better ensure the conservation of our native plants, animals and wild places. Future generations will thank you for it! Mike Britton
week at Kaitawa ever since. The results are impressive and the branch now considers Kaitawa “the jewel in our crown.” Planting along the Wharemauku Stream that runs through the reserve stabilise its banks and protects against floods; numerous walkers enjoy the scenic walk through new plantings of rimu, kahikatea, northern rata, totara, ngaio, carex, flax and many other natives that have supplemented the reserve’s “backbone” of remnant forest, and everywhere the tui and kereru swoop and feast on the abundance of food the native vegetation provides. John – who was awarded an Old Blue for his work here – says historic accounts of the area describe flocks of 100 kereru. The most he has seen in recent years is nine, but numbers are growing fast. He has also seen the occasional kaka, which probably venture across from Kapiti Island. At yet another Forest & Bird-tended reserve, Greendale, branch member Errol Hardy proudly shows us a profusion of tiny kahikatea seedlings – originating from a few 300-year-old kahikatea across the stream – popping up under the shelter of Forest & Bird’s plantings. Just a decade ago this was a racehorse paddock. The branch keeps up with demand for its ever-increasing plantings by growing on 5000 plants a year at its Waikanae nursery. Although in recent decades Kapiti has undergone enormous population increases and development, which inevitably
put immense pressure on the environment, David says improving community attitudes mean conservation is still outweighing destruction of the region’s natural places. “People are really beginning to value these places and appreciate that we need to look after them.” Educational leaflets distributed by the branch to Kapiti letterboxes on matters such as controlling cats and not dumping potentially invasive garden rubbish into reserves help spread the green message in the community. Where Forest & Bird was once in the minority in championing the conservation cause, conservation has now become “mainstream,” John says. “Forest & Bird has its beginnings in Kapiti, so it is continuing a long legacy. There are now lots of other groups doing work as well, but they are still following the same vision that Forest & Bird started.” Helen Bain

OREST & Bird’s display won a merit award at the Ellerslie Flower Show in November for the second year running. The exhibit, focusing on New Zealand’s fragile coastal environment, was designed by Forest & Bird field officers Nick Beveridge and Jacqueline Geurts to show visitors how important the coastal area is for providing habitat for some of New Zealand’s most vulnerable native species, from the little blue penguin to the katipo spider.
The koru shape of the display was inspired by the ram’s horn shell commonly found on New Zealand beaches, and the plants on display ranged from the large and well-known pohutukawa to smaller and lesser-known dune plants such as the shore bindweed. As well as raising awareness among the thousands of visitors to Ellerslie, Forest & Bird signed up scores of new members during the show. Helen Bain

OREST & Bird’s Lower Hutt Branch has hatched an ambitious plan to link natural wildlife sites in their local area. Its “Natural Lower Hutt” plan, initially devised by former branch chairman Russell Bell, aims to link up bush “corridors” to connect natural areas of bush in places such as Wainuiomata, Eastbourne and the Hutt Valley’s eastern hills and Belmont Regional Park and pockets of native vegetation on the opposite side of the valley. The plan would enable existing projects, such as areas of intensive predator control, habitat restoration and reintroduction of species, to be joined up and hopefully flourish further as a result. Green corridors enable native birds and other species to move from one area to another, rather than being isolated in small pockets of suitable
habitat. This means their gene pool can be widened and their numbers can increase – and they are likely to move into areas where more residents can see and enjoy them. Lower Hutt Branch Chairman Stan Butcher says the plan is challenging but he believes it is achievable. The biggest hurdle will be connecting the eastern and western sides of the valley, but Forest & Bird’s Upper Hutt Branch’s replanting project at Hull’s Creek in Silverstream is already well advanced and this could connect with a good stand of bush at the Keith George Memorial Park close by on the western hills. All five of Forest & Bird’s other branches in the region support the plan and it is hoped similar projects will be developed in their areas. Helen Bain
Waihou River restoration plantings
H
UNDREDS of hours of work by Forest & Bird’s Thames-Hauraki Branch are really starting to reap rewards on the west bank of the Waihou River. The riparian strip between the river and its embankment, which separates rural Hauraki from a salt meadow and the river, has been the focus of a group of Forest & Bird members led by Project Manager Ken Clark. The area from the mangrove margin of the river, which leads into a broad salt meadow, has been the target for enhancement. Clumps of salt marsh ribbonwood, marsh clubrush and some sprawling Muehlenbeckia complexa are the only natural colonisers of this area. However, the predominant plant is the introduced tall fescue. A considerable amount of experimental planting has taken place, with more than 20 different species of trees and shrubs planted out, both on the west bank and on the eastern side at Shelly Beach. The southern west-side strip has been the most successful, possibly due to it being the least
saline of the areas in this harsh environment, subject to tidal change and salinity. The best results have been achieved with ngaio, flax and pohutukawa. Kahikatea and puriri have given good but variable results, but most of the other species have failed. Over the past three years volunteers have put in more than 740 hours on the project. More than 600 plants were planted in 2007 with many more to come, as the local nursery is growing on another lot of seedlings to a suitable size. The timing for the completion of this project is fortuitous, as it is expected to coincide with the completion of the hydrology studies for the ecological rehabilitation of the Kauaeranga Valley floodplain. This major project at the entrance into Thames township is a combined Department of Conservation, Environment Waikato, Thames-Coromandel District Council and Forest & Bird initiative. Hopefully planting on this project will start in 2008, after associated earthworks and walkways have been completed. Doug Ashby

New Zealand’s Wilderness Heritage By Les Molloy and Craig Potton, 320 pp, hardbound, Craig Potton Publishing, 2007, RRP $89.99
T
HIS impeccably presented book on New Zealand’s spectacular wilderness landscapes, habitats and species would be my pick for a 2007 book of the year. The quality and reproduction of the 300 photographs is second to none. They are so sharp and clear they seem almost threedimensional on the page. The book is structured around thirteen regional chapters which detail the incredible variety of landscapes, offshore islands and geothermal and glacial features which make New Zealand “many countries in one”. Over the course of 320 pages it manages to pack in more than this with its thoughtful descriptions of our main protected areas, the flora and fauna values protected within them, and the many species that live in and between them, and how these varied landforms, ecosystems and species evolved into what they are today. The wilderness heritage theme flows through the book, with areas of untamed nature described as tranquil places of reflection and solitude to be set aside from industrial activities such as commercial logging, fishing and mass tourism. It also has a lot to say about conservation, including a vision for better protecting this unique wilderness heritage. One of the most powerful points made here is that, despite having the world’s fourth largest exclusive economic zone (EEZ), relatively little is protected within New Zealand’s marine environment. We ought to treat New Zealand’s ocean wilderness areas as we’ve treated fully protected areas on land and set aside more as no-take marine reserves to match terrestrial protection. Ultimately, like New Zealand itself, it is the scale and variety of this important book that is so impressive. 46 FOREST & BIRD • FEBRUARY 2008

HIS visually stunning popular book on the world’s birds is an impressive collaboration between the publisher and BirdLife International. The superb photographs of over 1500 species and informative text convey the variety and complexity of avian life, with a CD of 60 bird songs adding a welcome dimension to the sensory experience. A comprehensive introductory section covers bird biology, behaviour, distribution, migration, nesting, flight, song and conservation with examples from a wide range of species. This is followed by generous layouts on the 32 main habitat types which birds are found in and several more on the main threats to their survival. Then you get to the main body of the book: 380 pages covering every bird family and over 1000 representive species. Each bird family has its own introduction and 24 world class birdwatching sites are profiled. The user-friendly design means the book is accessible to younger readers, yet contains enough up-to-date information to hold the interest of readers already familiar with the basic facts about the world’s birds. The three bird families unique to New Zealand - kiwis, New Zealand wattlebirds and New Zealand wrens - are included. With the exception of the birds of paradise that occur in and around New Guinea, relatively few Pacific Island species are covered in depth. In comparison with other large format photographic books of this length this major work is reasonably priced.

HIS volume completes the series, which has been a major undertaking for Birds Australia, the BirdLife International Partner in that country. Taken together, this series offers a comprehensive contemporary synthesis of information on the bird species of the two countries and one region of the title. You could say it is also the most academic of the bird books reviewed here. Volume seven will be of most interest to New Zealand readers because it includes the wattlebirds, pipits, swallows, fernbirds and white-eyes, as well as many introduced species such as Australian magpie, rook, house sparrow, various finches and buntings, both the thrushes, common starling and common myna. Each species account runs to several pages which means these are, in effect, scientific papers summarising all published information on each. The paintings of each species and their sub-types are especially good. Derek Onley’s portraits of both subspecies of kokako, including a juvenile bird and an adult bird in flight, are among the highlights. The only disappointment with the paintings is that the huia is not included. I found myself wondering why, when the New Zealand piopio is. Both species are thought to have become extinct early in the twentieth century and it could be argued that the huia is the more visually interesting of the two species. At the price, this is one for the experts. w w w. f o r e s t a n d b i r d . o r g . n z

Handbook of the Birds of World Vols 11 & 12 By Josep del Hoyo, 800pp, Lynx Edicions, hardbound, $397 per volume
S
INCE Volume One appeared, this series has been widely accepted as the definitive reference work on the world’s 10,000 bird species. These two most recent volumes in a projected series of 16 get off to a powerful start with absorbing introductory essays on the ecological role of birds and the evolution of birds. The essay in Volume 12 draws on the latest fossil evidence and includes interesting examples from this part of the world. The bird families covered in Volume 11 include the fantails, flycatchers and monarchs, many of which occur in the Pacific Islands. The endemic New Zealand fantail is also included among the 44 fantail species covered. Volume 12 has a stronger emphasis on Australian and New Zealand bird species covering the babblers, logrunners, whistlers, Australasian robins and fairywrens. The yellowhead (mohoua), whitehead (popokatea), brown creeper (pipipi), New Zealand tomtit (riororiro), New Zealand robin (toutouwai) and Chatham Island black robin are all covered. In the absence of a comprehensive, up-to-date guide book to the birds of the Pacific Islands, this series offers the most in-depth contemporary account of them. Each species is illustrated with specially commissioned paintings which show the different plumages of the sexes and juvenile stages necessary for field identification.

Southern Alps – Nature & History of New Zealand’s Mountain World By Alison Ballance, 320 pp, hardbound, Random House, 2007, RRP $89.99
T
HIS delicious book celebrating the Southern Alps by award-winning natural history film-maker and writer Alison Ballance contains everything you ever wanted to know about their geology, human history and natural history. Presented in an absorbing narrative, the stories of the geological and biological processes that have combined to create the Southern Alps unfold in breathtaking detail. Alison Ballance’s subtle descriptions of the alpine flora, and close encounters recalled with alpine zone birds such as kea and rock wren, are riveting. She weaves together epic journeys and explorations of mountains and glaciers with picturesque habitats from alpine flower gardens and wetlands to beech forests and tussock grasslands to tell the monumental story of “the backbone of the country”. The spacious design is an engaging blend of historical graphic illustrations, old black and white photographs and contemporary colour images of landscapes and species by Arno Gasteiger, Rod Morris and others. A few of the colour photographs that appear later in the book do not seem to have reproduced quite as well as might have been expected, so in a couple of instances they seem slightly washed out. The photographs of nineteenth century climbing attire on pages 267 and 268 are gems among the more than 300 images. These help make this the value for money publication it undoubtedly is.

T is a reflection of the state of the world’s bird species that there is now a publication which focuses solely on the plight of the 189 that are critically endangered. Compiled in cooperation with BirdLife International, this new yearbook includes an entry of up to two pages for each species, complete with its history, latest information on its status, and the measures being taken to protect it. Each species is illustrated in colour, with many of the photographs published for the first time. It includes useful notes on each country. For example, the USA, together with its overseas territories, and Brazil both have more critically endangered species (25) than any other country. This is nearly three times as many as New Zealand, which has nine – all included in this publication. In the South Pacific region Australia and French Polynesia each have six. It also contains two special sections on climate change and ecotourism which set out the scale of the threat posed to birds by the former, and potential for the latter to help save some of the species covered in the book. Copies can be ordered online from www.rarebirdsyearbook.com For each copy sold, the publishers will donate $10 to BirdLife International’s conservation work.
