Excerpt from Evaluation of a Habitat Capability Model for Nongame Birds in the Black Hills, South Dakota Coefficients in the habcap model quantify rela tive (o to capability of each structural stage as habitat to sustain a prescribed population density for each species. The habcap model includes separate coefficients for feeding and cover. Although feeding and cover coefficients are the same for most species, we based our test of the model on cover coefficients because cover includes nest placement in breeding territories. Abundance of bird species at each site Was the sum of observations S50'm from the count point. We used bird count data from 1992 and 1993 to test hypotheses that the observed abundance in each structural stage was similar to predicted abundance by the habcap model using chi-square goodnessof-fit tests (freese Chi-square tests were made only for structural stages with coefficients >0. Since fewer counts were made in old-growth and dry meadows, predicted abundance in these structural stages was adjusted to represent the proportion of total count days. Predicted abundance of bird species (pnj) in each structural stage (ssi) was calculated as. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Habitat models have considerable economic effects on management decisions and are used to predict consequences of land management decisions on wildlife. The Black Hills National Forest uses the habitat capability model (HABCAP), but its accuracy relative to resident wintering bird populations is largely unknown. We tested the model's predictive accuracy for resident nongame birds wintering in 11 vegetation structural stages of ponderosa pine, quaking aspen/paper birch, and meadows in the Black Hills, South Dakota. Six species, hairy woodpecker, gray jay, black-capped chickadee, white-breasted nuthatch, red-breasted nuthatch, and dark-eyed junco, had HABCAP coefficients for vegetation structural stages during winter. Red crossbills were not previously included in the model, so we developed HABCAP coefficients for them. Predicted abundance of winter birds in vegetation structural stages based on HABCAP coefficients differed from observed abundance for gray jays, black-capped chickadees, white-breasted nuthatches, red-breasted nuthatches, and dark-eyed juncos. HABCAP coefficients were modified to reflect observed abundance patterns of birds. These changes to HABCAP coefficients should provide managers with more appropriate estimates of land management impacts on nongame birds wintering in the Black Hills.
