Terrestrial Biological Inventory Hartwell Drainage and Levee District Greene County, Illinois.
Abstract
The St. Louis District, Corps of Engineers, in planning for improvements to flood control structures for the Hartwell Drainage and Levee District along the lower Illinois River, has contracted for an evaluation of local terrestrial wildlife and vegetation. Nine habitat types were identified: bottomland forest, old field, border habitat, shrub wetland, emergent wetland, pond, drainage ditch, developed land, and agricultural land. Approximately 93 percent of the project area is composed of agricultural land. Qualitative evaluations were made at 27 locations in the District and along flanking streams. common plants and vertebrate animals occurring in each of the habitats were identified. A variety of wildlife species are potentially present, but the most common animals are those which prefer or require a diversity of habitat types. Human activities which may affect wildlife populations in the District are cited, and alternative actions are recommended. Continued conversion of forest, old field, wetland, and border habitats to agricultural land is the primary factor affecting wildlife populations in the District. (Author)
