Mammals At Hidden Springs State Forest, Shelby County, Illinois, Leslie L. Clapp Jan 1985

Mammals At Hidden Springs State Forest, Shelby County, Illinois, Leslie L. Clapp

Masters Theses

A survey of the mammals at Hidden Springs State Forest (HSSF) in Shelby County, Illinois was conducted from May 1 to November 18, 1984. The survey was designed to determine the species and relative abundance of mammals associated with major habitat types of the Forest based on area walk-through surveys, streamside surveys, mist net surveys, snaptrap/pitfall surveys, and a hunter questionaire. A total of 26 mammal species were found associated with various habitats within the Forest and an additional four species were reported within Shelby County. One species, the southeastern shrew (Sorex longirostris) had not previously been reported in ...


Winter Concentration Areas Of White-Tailed Deer (Odocoileus Virginianus) In Illinois: A Discriminant Analysis, Paul A. Brewer Jan 1985

Winter Concentration Areas Of White-Tailed Deer (Odocoileus Virginianus) In Illinois: A Discriminant Analysis, Paul A. Brewer

Masters Theses

Two discriminant models were derived from 40 variables measured in 12 white-tailed deer (Odocoileus virginianus) winter concentration areas and 12 non-concentration areas in east-central Illinois. The first model correctly classified 100% of these areas based on area of refuge, area of upland hardwoods with <50% crown closure, area of bottomland forest with <50% crown closure, distance of unimproved roads, and total topographic relief. This model was tested on 6 winter concentration areas in west-central Illinois and 6 winter concentration areas in northern Illinois. The first discriminant model correctly classified 91.7% of these areas.

The second model originated from the same set of variables, however the refuge area variable was removed in an attempt to classify winter concentration areas without knowledge of refuge areas. This model correctly classified 91.7% of sites in east-central Illinois, and 75% of the areas in west-central and northern Illinois.

Refuge accounted for nearly 59 ...
