Selection Of Nesting Habitat By Sharptailed Grouse In The Nebraska Sandhills, Bart L. Prose, Brian S. Cade, Dale Hein Jun 2002

Selection Of Nesting Habitat By Sharptailed Grouse In The Nebraska Sandhills, Bart L. Prose, Brian S. Cade, Dale Hein

United States Geological Survey: Staff Publications

We evaluated nesting habitat selection (disproportionate use compared to availability) by plains sharp-tailed grouse (Tympanuchus phasianellus jamesi) on rangelands grazed by cattle (Bas taurus) relative to height, density, and heterogeneity of residual herbaceous vegetation remaining from previous growing seasons. Residual cover is critical for nesting sharp-tailed grouse and can be lacking on grazed rangelands. Aerial photography and a geographic information system were used to analyze residual cover height classes and several measures of residual cover heterogeneity in nest (n = 38) and random (n = 38) plots. Height classes corresponded to visual obstruction readings (YORs), the …
