If you’re a gardener like me, you know how exciting it can be when those gardening catalogues arrive in the mail each spring. I flip through the pages looking for new ideas and plants to help expand and improve my garden landscape. It’s a rite of passage. Part of the joy and fun of gardening is that you are really never done! It’s a work in progress. Gardens have a wonderful way of changing the landscapes of our yards, and lives, over time. Humans have changed our county’s landscape in ways we can’t even imagine. A few hundred years ago, the landscape in what is now Lake County was roughly 40 percent prairie. Today, only remnants of those early prairies exist. Much of the county’s landscape is a built environment. In suburban Lake County, major changes, such as the construction of a building on land that was once a cornfield, are easy to see. But it can take time, an experienced eye, and patient observation to “read” the subtler changes in the non-built environment–in our woodlands, wetlands and other wild places. In this issue, we highlight the Vegetation Monitoring Program led by our staff ecologists. These scientific professionals spend hours in the field trying to understand which plants are growing where so they can help keep them healthy. They determine how plant species and ecosystems change over time and why, and they find ways to encourage the health and balance of our preserves. They use the tools of science, including data collection over long stretches of time, to research trends so we can better protect native species and improve Lake County’s natural landscape. This spring as nature’s garden blooms, look for the work of our ecologists in forest preserves throughout the county. You’ll see the results of their efforts in the green and white sea of large-flowered trillium (Trillium grandiflorum), and the sweet, shy purple of the pasque flower (Pulsatilla patens) or, if you’re lucky, the delicate and rare eastern prairie fringed orchid (Platanthera leucophaea). pasque flower

Stems + Stats OUR ECOLOGISTS MONITOR PLANTS TO PROTECT NATIVE SPECIES If you’re traveling a trail in the forest preserves and notice a pair of steel T-posts in the ground separated by some distance, you’ve probably discovered a permanent transect. They’re crucial to our Vegetation Monitoring Program, which tracks what plants are growing where so we can better protect native species.

preserves,” said Restoration Ecologist Ken Klick, who leads the program. “These small sample plots of land allow us to record and

analyze the changes in plant species that happen over time with and without land management.”

Transects are 100-meter fixed paths through a natural area, capturing different ecosystems and species within them. Permanent starting and ending points are marked with GPS—and those steel posts. To date, we’ve established more than 300 transects in high-quality prairie, woodland, and wetland communities throughout the forest preserves, including in restoration areas and new acquisitions. “When a transect location is selected, we look for fairly uniform sites, ones that don’t cross into different plant communities,” said Klick. “For example, you’re not crossing a barbed wire fence that suggests one half of a transect has been grazed.” Every five meters along a transect, Klick and fellow Natural Resources Department staff identify all plants growing within a square meter area—a quadrat. Plant identification relies on professional knowledge, field

1. SPECIES RICHNESS The number of species in a given ecosystem.

2. FLORISTIC QUALITY INDEX A quantitative measure of a plant community’s regional rarity, based on the mean coefficient of conservatism.

3. COEFFICIENT OF CONSERVATISM A value assigned to a native species, on a scale of 1 to 10, indicating how likely you are to find that species in a landscape. A plant scored at 9 or 10 has specialized habitat requirements and tends to live in undisturbed, high-quality areas, while a plant scored at 1 or 2 can grow in many habitats. Non-native species are scored at zero. This scoring system is unique to the Chicago region.

4. RELATIVE IMPORTANCE VALUE An indicator of how dominant a species is in a given ecosystem, based on relative frequency and coverage.

measurements help indicate the health of the preserves. These stats also serve as baseline metrics, allowing Klick and colleagues to draw conclusions about how land management efforts affect plant communities. “As we acquire new forest preserves, we establish transects to record the current condition before we begin land management efforts, such as controlled burns,” said Restoration Ecologist Matt Ueltzen. “New acquisitions are often degraded due to past land uses or lack of stewardship, but still hold valuable plant communities.” During and after management, stats are collected at these sites every five to seven years to capture any changes. In 2013, we worked with a statistical consultant to determine how vegetation diversity, structure, and composition have shifted in different types of plant communities since our monitoring program began. Their analysis produced some take-home lessons. Land management efforts, including controlled burns, invasive

A VALID CONCERN Our 100-year vision drives us toward preventing any additional native species from disappearing in Lake County. Data collected through plant monitoring help us make sure that common species remain common and that rare, threatened, and endangered species receive continued protection and assistance. Many partners join us in these efforts, such as Plants of Concern. Managed by the Chicago Botanic Garden, Plants of Concern is a regional rare plant monitoring program supported by public and private conservation agencies, landowners, and volunteer groups. During monitoring season, Plants of Concern volunteers accompany our staff.

Klick is concerned about fast-growing, heat-loving johnsongrass (Sorghum halepense). “I’m concerned because it’s proven to be terribly invasive 200 miles south of us,” he said.

SEED FROM THE CHAFF You can separate the seed from the chaff in sports, in job interviews—and in our Native Seed Nursery at Rollins Savanna (Grayslake). There, staff and volunteers harvest seed from Lake County’s rarest plants. Each week, volunteers don gloves and separate chaff from the seeds of carefully harvested species, such as slender wheatgrass (below), wild senna, and raven’s foot sedge.

Interesting vignettes, such as this assassin bug nymph resting on a wild geranium (Geranium maculatum), are often found during data collection.

How we keep native plants healthy and abundant, and how we stop the rarest ones from vanishing, are critical questions we must continually ask. It will take generations of land stewardship and careful action by ecologists, stewards, volunteers,

Some species release seeds with a swipe of the hand. Others are sifted with screens. For time-consuming or fluffy species, Nursery Coordinator Kelly Schultz has devised machines from household items to speed the process or reduce dust. Her "milkweed machine" (below) is a red trash bin with nail-studded wood slats and PVC pipe. As the lid turns, seeds separate from the fluff and fall through mesh at the bottom, where they’re collected.

and citizen scientists to answer them. Ueltzen expressed measured optimism. “I’d like to say they’ll be maintained by our efforts and those of others,” he said. “Time will tell. It can take from five to 100 years or longer for the effects of land management to become apparent.” Klick thinks it can be done. Gesturing at a map of protected lands, the gray of development punctuated with pearls of green, he said, “Our forest preserves are tiny islands of green surrounded by a sea of inhospitable habitat for our

“The nursery is a tremendous asset,” Klick said. “It allows us to collect rare seed and put local genotypes into suitable habitat. Local seeds tend to do better than seeds from hundreds of miles away, because they’ve adapted to Lake County’s natural areas over thousands of years.”

PRESERVENEWS Science IN THE PRESERVES We are serious about our goal to eradicate the non-native invasive species, buckthorn, from our forest preserves and beyond. In 2015, we convened several regional organizations to discuss ideas for controlling buckthorn. This conversation was organized to launch a pilot project to improve landscapes within the vicinity of Middlefork Savanna (Lake Forest). Around that same time our Assistant Public Affairs Manager, Allison Frederick, forged a partnership with social scientists at the U.S. Forest Service (USFS). Eager to discuss applicable methods for behavioral change and conservation psychology, she teamed up with researchers at the USFS to determine people’s perceptions of the trees and aesthetics in the buckthorn pilot area. Last summer, we distributed a homeowner survey to research the best ways to eradicate buckthorn and support native landscapes. All residents within the pilot project area received the same questionnaire. The survey consisted of multiple choice and open-ended questions, following a format based on the Theory of Planned Behavior, a well-accepted way of predicting people’s intentions to act on a given issue. These important predictors have been successfully used in many studies of land management. Related questions about people’s activities and values regarding yards, landscaping, and the environment will help us better understand their willingness to take action. Over the past six months, Frederick and colleagues have compiled and analyzed responses. Participation and responses to this survey will be used to enhance outreach efforts, focus restoration activities, and inform similar projects throughout the region. Frederick and USFS partners will be presenting their key findings at the U.S. Regional International Association for Landscape Ecology Annual Meeting this April in Chicago. Homeowners who participated in the survey received a report of results and the first invitations to join us in this effort to build a more resilient future for Lake County.

CHECK ONLINE MAP FOR TRAIL CLOSURES Although spring brings warmer trail-going weather, it also brings increased rainfall and snowmelt, putting trails at risk for flooding. After submerged sections dry, our maintenance crews are quick to regrade and repair any water damage. Before heading out, check LCFPD.org/closures for trail status.

PRESERVE AND TRAIL IMPROVEMENT PROJECTS Several trail and preserve improvement projects are planned for completion this year, weather permitting. Here are a few highlights. Check LCFPD.org/projects for updates on all projects. Lyons Woods to Waukegan Savanna Trail Connection: We’re partnering with others to create a 2.3-mile paved trail connecting the Robert

McClory Bike Path at Lyons Woods to the Green Bay Road right-ofway. Opening this summer. Waukegan Savanna Dog Park: Canines will soon have a new off-leash dog area to exercise, play and socialize. The entrance is at the

northeast corner of Delany and Yorkhouse Roads. Opening late fall. Spring Bluff Observation Deck and Trail: An existing asphalt roadway is being converted to a 0.7-mile trail, and a new wildlife education and observation deck is being built. Opening late 2018.

STRATEGIC PLAN UPDATE

LCFPD.org/vision

Building on our organization’s five core values of Pride, Leadership, Communication, Collaboration, and Respect, we are striving to become one of the “Best Places to Work in Illinois.” This program is designed to recognize outstanding places of employment in Illinois. Results of a two-part assessment— an employer questionnaire and an employee survey— help determine the organizations that make the list. Information from the questionnaire and survey is combined to produce a detailed data set enabling analysts to determine the strengths and opportunities of participating organizations.

CARING FOR OUR SHARED LANDSCAPE, NATURALLY

Lending a hand (and shovel) is second nature for Bluestem Ecological Services. Upon learning of our Buckthorn Eradication Pilot Project at Middlefork Savanna (Lake Forest), Bluestem donated all plant materials and labor to install a demonstration garden— a well-labeled native plant habitat, sized for the residential landscape—on Elawa Park property, near the preserve entrance. Thanks to this collaboration between the Lake County Forest Preserves, Bluestem, and the City of Lake Forest, by mid-2018 native plants will be in full bloom, accompanied by interpretive signage detailing the value of planting natives to both humans and wildlife. To learn more about how and why to remove buckthorn and plant native species in your yard, visit LCFPD.org/landscaping.

Many Thanks Throughout much of 2017, Forest Preserve education staff had a little extra help, thanks to ComEd. Nearly all of our education programs support Illinois Learning Standards in STEM (Science, Technology, Engineering and Math), and a $25,000 grant allowed us to hire the ComEd Science Instructor to help deliver STEM programs in schools and through field trips in the preserves. With ComEd’s support, we were also able to incorporate new technology into existing program curricula. Partnerships like this are critical to the education mission of the Lake County Forest Preserves. Thank you, ComEd!
