"The Sinkhole Plain Area Assessment covers an area of about 1,228 miles2 (785,822 acres) in southwestern Illinois bordering the Mississippi River. It includes all of Monroe, much of St. Clair, and portions of Randolph and Madison counties. The area encompasses 17 sub basins along the Mississippi and Kaskaskia Rivers, of which six have been designated as a ""Resource Rich Area"" because they contain significant natural community diversity. The Sinkhole Plain Ecosystem Partnership was subsequently formed around this core area of high quality ecological resources. This assessment is comprised of five volumes. In Volume 1, Geology discusses the geology, soils, and minerals in the assessment area. Volume 2, Water Resources, discusses the surface and groundwater resources and Volume 3, Living Resources, describes the natural vegetation communities and the fauna of the region. Volume 4 contains three parts: Part I, Socio-Economic Profile, discusses the demographics, infrastructure, and economy of the area, focusing on the three counties with the greatest amount of land in the area -Monroe, Randolph and St. Clair; Part IT, Environmental Quality, discusses air and water quality, and hazardous and toxic waste generation and management in the area; and Part III, Archaeological Resources, identifies and assesses the archaeological sites known in the area. Volume 5, Early Accounts of the Ecology of the Sinkhole Plain, describes the ecology of the area as recorded by historical writings of explorers, pioneers, early visitors and early historians."
