The Changing Illinois Environment: Critical Trends

"Ecosystems in Illinois are deteriorating, their natural functions disrupted by fragmentation and stress."

So concluded The Changing Illinois Environment: Critical Trends, a state-of-the-environment report published in 1994 by the Illinois Department of Energy and Natural Resources (now the Illinois Department of Natural Resources).  This report recommended that the state begin collecting statewide data on both the extent and condition of its ecosystems in order to determine the most effective and economical natural resources policy.   General program reports are listed below in chronological order.  


Still going!

Note that the CTAP remains active, and Illinois Natural History Survey researchers continue to monitor sites across Illinois. See the CTAP Website for the latest information about the program and program contacts.
