This is a product of the Critical Trends Assessment Program (CTAP) and the Ecosystems Program of the Illinois Dept. of Natural Resources (DNR). Both are funded largely through Conservation 2000, a six-year State of Illinois initiative to enhance nature protection and outdoor recreation by reversing the decline of the state's ecosystems. Conservation 2000 is the culmination of recommendations from CTAP, the Illinois Conservation Congress, and Governor Edgar's Water Resources Land Use Priorities Task Force.--T.p. verso.
