Land Use Changes and Pheasant Declines in Eastern South Dakota
Changes in pheasant (Phasianus colchicus) nesting habitat were investigated on Windsor Township, Brookings County, South Dakota. The population was censused, nesting densities determined, cover was mapped, and an interspersion index determined in 197 7 and 1978. Comparison to a similar study …

Pheasant Nesting and Vegetation Development in Dense Nesting Cover Established Under the South Dakota Pheasant Restoration Program
Pheasant (Phasianus colchicus) nest use of dense nesting cover (DNC) established under the Pheasant Restoration Program was evaluated in Beadle, Codington, Tripp, and Walworth Counties in South Dakota from 1978 to 1981. Nest densities and success in DNC plots were compared to those found in …
