GIS-BASED HABITAT MODELS FOR MOUNTAIN GOATS

We used logistic regression to develop habitat models from observation of mountain goats (Oreamnos americanus) in alpine habitats near Mt. Evans, Colorado. Mountain goats used areas near escape terrain, on moderate slopes, at midelevations, and on southerly exposures more than expected. Habitat mode...

description We used logistic regression to develop habitat models from observation of mountain goats (Oreamnos americanus) in alpine habitats near Mt. Evans, Colorado. Mountain goats used areas near escape terrain, on moderate slopes, at midelevations, and on southerly exposures more than expected. Habitat models for summer, winter, or all-seasons correctly classified 81-83% of observations and incorrectly classified 12-13% of locations not used by mountain goats. A model based only on distance to escape terrain correctly classified 87% of observations and classified 38% of the study area as suitable habitat. Our models provide a way to use readily available data and simple techniques to quickly identify suitable habitat over large geographical areas.
