1 Urban Nature Needs Special Care Renewing the Promise of the Forest Preserves of Cook County for People and Nature Chicago Region

2 Forest Preserve District of Cook County Established in ,000 total acres protected 55,000 acres in a natural state

3 Forest Preserve acquire... and hold lands containing one or more natural forests or parts thereof or lands connecting such forests or parts thereof, or lands capable of being forested, for the purpose of protecting and preserving the flora, fauna, and scenic beauties within such district, and to restore, restock, protect and preserve the natural forests and such lands together with their flora and fauna, as nearly as may be, in their natural state and condition, for the purpose of the education, pleasure, and recreation of the public... From the Illinois Enabling Act Woodland sunflowers bloom in an oak savanna

4 People Worked to Protect Nature… Many people, including Jens Jensen and Dwight Perkins, had the vision to protect nature for future generations. They thought the job was done, the land was protected and nature would carry on … Jens Jensen Illinois Prairie Club circa 1900 Dwight Perkins

5 Protection Wasnt Enough... Buckthorn has killed off the wildflowers, grasses and even the tree seedlings. Native plants and animals were disappearing Open areas were becoming impassable New plants began replacing others over large areas Our protected preserves began to look radically different.

6 The very things we wanted to protect were disappearing WHY?

7 Why was protection not enough? Fragmentation Human population increase Lack of human set fire Introduced plant and animal species Changed hydrology Changed human relationship with nature Morton Arboretum scientists in the field. The conditions have radically changed.

8 Humans in a sea of nature Land Cover cir. 1800Land Cover cir Nature in a sea of humans

9 How Conditions Changed: Lack of Fire Our ecosystems developed through time with human set fire Woodlands, wetlands, savannas, and prairies need fire to keep shrubs and trees in balance Fire supports the growth of woodland grasses and flowers. Lack of fire allows shrubs to invade this savanna

10 How Conditions Changed: Lack of Fire Pale purple coneflower seeds germinate faster with smoke! Without fire, Without fire, these sun loving flowers will not survive Fire maintains the prairie as home for the threatened Franklins Ground Squirrel Lack of fire allows invasive buckthorn to grow

11 Crowd out native plants and animals Are junk food for wildlife After outright destruction, is the most critical threat to natural lands How Conditions Changed: Introduced Non-native Species Garlic Mustard snuffed out all the wildflowers Oriental Bittersweet will smother trees Purple Loosestrife destroys a wetland

12 Unique Communities Homes for Rare Animals and Plants Reduce Climate Change Protects Water Quality & Reduces Flooding Is More Family Friendly Why the Health of Urban Nature Matters

13 Why the Health of Urban Nature Matters Unique Communities Continental meeting place of woodland, savanna, prairie, and wetland communities Oak Savanna - more endangered than the rainforest Animal and plant communities not found anywhere else on earth Forest preserves are home to carnivorous sundews and sand loving cactus!

14 Why the Health of Urban Nature Matters The greatest number of rare animals and plants find a home here in Northeast Illinois. Upland Sandpiper Hines Emerald Dragonfly Henslows Sparrow Franklins Ground Squirrel Blandings TurtleSnowy Egret

15 Why the Health of Urban Nature Matters Climate Change Healthy Preserves: Capture carbon at many levels Lock more carbon into the soil Are more resilient Illustration: Chicago Wilderness Illustration: Heidi Natura, Conservation Research Institute

16 Why the Health of Urban Nature Matters Water Quality and Flooding Healthy Preserves: Dont have soil erosion Allow water to soak into the soil Keep pollution out of rivers, lakes and streams Clean the water before it enters lakes Dense shade killed off the wildflowers and grasses that anchor the soil. With every rain, soil washes into the river.

17 Why the Health of Urban Nature Matters Family Friendly

18 How do we ensure that the Preserves are healthy and continue to provide all the benefits just described? We must restore the conditions that support healthy nature in our Preserves!

19 The Conditions for Healthy Nature Prairie, almost full sunlight 0-10% canopy Savanna, sunny with some shade 10-50% canopy Woodland, dappled sunlight 50-80% canopy Forest, less light % canopy © Paul Nelson, The Tallgrass Restoration Handbook

20 Controlling Invasives and Restoring Structure Collecting and Planting Seeds Renewing the Promise. People and Nature - Working Together Again Returning Fire Monitoring the Results

21 People and Nature - Working Together Prescribed Fire A carefully planned and managed fire is conducted to achieve a goal - healthy communities for plants and wildlife. Conducted only under specific safety standards and weather conditions by trained personnel.

22 People and Nature - Working Together Prescribed Fire No other method accomplishes everything that fire can

23 Pulling Garlic Mustard Cutting down buckthorn Treating cut stumps with herbicide People and Nature - Working Together Control Invasives & Restore Structure

24 Seed collecting in a remnant prairie People and Nature - Working Together Collecting and Planting Seeds

25 This People and Nature - Working Together Lacking fire this oak woodland became choked with buckthorn.

26 All the ground vegetation had been killed by buckthorn. With Buckthorn Gone… an Oak Woodland is Revealed

27 With increased sunlight and seeding with native plants,this area is recovering. Three Years Later, the Woodland is Thriving

28 With the resumption of management the number of plants and animals increases though time. The amount of human effort decreases - community health increases

29 By keeping humans and nature interacting through the ecological management our Preserves, we will ensure their health for our children and their children in perpetuity.

30 Monitoring the Results of the Work Are we restoring the conditions that support healthy nature? How are species composition and habitat structure changing? How are species of conservation concern doing?

31 Oak Health in the Forest Preserves Oaks are being replaced by other species and are not reproducing Not a single seedling white oak was found Data from the 2007 Cook County Land Audit, Audubon - Chicago Region
