ECOSYSTEM MANAGEMENT AND RESTORATION ECOLOGY

The landscape of Illinois has been drastically altered since the first settlers arrived in the 1800s. The vast prairies, punctuated by forests, savannas, and wetlands, are gone and agricultural uses now dominate the land. More than 99% of the grasslands, 90% of the wetlands, and about 65% of the forests have been converted to other uses and nearly all of the remaining areas are degraded in some significant fashion. Rivers, streams, and water bodies of all sorts have been degraded by channelization, drainage, damming, and sedimentation. Despite these severe losses of habitat, opportunities exist in Illinois for large-scale management at the ecosystem level. 
The Illinois Natural History Survey (INHS) has long conducted restoration and ecosystem research. We work in all the major ecosystems in Illinois including prairies and savannas, forests, wetlands, and waterways ranging from small streams to large rivers. The Survey is involved in many small- and large-scale restoration projects. Among these are the enormous Midewin National Tallgrass Prairie and the Lost Mound Unit of the Upper Mississippi National Wildlife Refuge (formerly the Savanna Army Depot). On these areas that were once military reservations, INHS scientists are cooperating with federal agencies in prairie and savanna restorations. Research is focusing on how various restoration and management techniques affect the plant and animal communities. At Midewin, Survey scientists are cooperating with federal management biologists in prairie and savanna restorations, especially in monitoring birds and threatened and endangered plant species. The Lost Mound Unit is an area that was never plowed and is dominated by native sand prairie and savanna vegetation. Over time, road and building construction, intensive grazing, and the lack of natural fires have degraded the natural vegetation. INHS scientists at the Lost Mound Unit are working closely with the Fish and Wildlife Service to manage, restore, and monitor the response of the community in the 3,500-acre upland portion of the area.

On the Cache River in southern Illinois, partial restoration of the normal hydrologic flows and channels is being studied by Survey researchers with the intent of providing information that will be useful in restoration of the river's rich lowland hardwood wetlands and forests. We also are involved in research that will help to restore the backwater lakes, wetlands, riparian forests and other habitats along the Illinois River.

At the James Edgar State Fish and Wildlife Area (formerly Site M), Survey scientists are comparing how traditional management practices and restoration at the ecosystem level affect the population ecology of the Northern Bobwhite.

Survey scientists are enthusiastic contributors to these conservation efforts, partnering with state and federal agencies and private organizations to restore and enhance Illinois' natural resources.
