Habitat Suitability Index Models: Yellow perch
Douglas A. Krieger, James W. Terrell, Patrick C. Nelson
1983, FWS/OBS 82/10.55
A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for yellow perch (Perca flavescens). The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for riverine, lacustrine, and palustrine habitat in the 48...

The Rocky Mounta in subspecies (S. t. nataliae) exhibits altitudinal and latitudinal...
Habitat Suitability Index Models: Baird's sparrow
Patrick J. Sousa, W. Neil McDonal
1983, FWS/OBS 82/10.44
A review and synthesis of existing information were used to develop a habitat model for Baird's sparrow. The model is scaled to produce an index of suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for Baird's sparrow habitat in the Northern Great Plains.
