| Notes: | "Critical Trends Assessment Program"--Cover.
"March 1997."
"The Cache River Area Assessment examines an area that includes the majority of the Cache River watershed in extreme southern Illinois. Because significant natural community and species diversity is found in the area, it has been designated a state Resource Rich Area. This report is part of a series on Illinois Resource Rich Areas where public-private partnerships have been formed. These assessments provide information on the natural and human resources of the areas as a basis for managing and improving their ecosystems. The determination of resource rich areas and development of ecosystem-based information and management programs in Illinois are the result of three processes -- the Critical Trends Assessment Program, the Conservation Congress, and the Water Resources and Land Use Priorities Task Force."--P. iii, v. 1, pt. 1.
