Ecosystem Monitoring Expanding the scientific foundation To move the statistical base of collaborative natural resource management into the future, new methods of research were created. Historical assessments based on fragmented data has been replaced with a long-term monitoring network that will provide timely information on the condition of the major ecosystems. CTAP scientists from the Illinois Natural History Survey conduct detailed biological inventories of 150 randomly selected sites for each of four habitat types — forests, streams, wetlands and grasslands. Trained volunteers in the EcoWatch Network carry out less detailed biological surveys at several hundred sites. Together the two groups collect a representative set of biological indicators that measure environmental quality. The indicators include information on plants, birds, fishes and insects that will track changes in ecosystems. As data accumulate over the years, regional and statewide trends will become apparent. This information will support efforts to preserve, restore, and manage ecosystems across the state. Streams and Wetlands The streams data collected suggest that some watersheds are better off than others, although no watershed ranked high on all stream quality indicators. Wetlands in Illinois have declined to only of the state and few remain in a high-quality condition. CTAP wetland monitoring sites contain an average of 15 plant species, with two of them introduced. The number of wetland-dependent bird species found at the typical site is low, species on average. A healthy wetland should host 6-10 wetland- dependent II Wetland Restoration.
