Abstract
A geographic information system (GIS) model was developed for pygmy rabbit (Brachylagus idahoensis) habitat in southeastern Idaho. Areas of potential use by pygmy rabbits were determined from appropriate vegetation and geological classes in a GIS analysis. Sites most likely to be occupied within potential vegetation and geologic habitat were determined by including appropriate slope and aspect measurements. Randomly selected areas within and outside of predicted areas were searched for pygmy rabbit sign. This resulted in a 57% probability of predicting areas occupied by pygmy rabbits and a 100% probability of predicting areas not occupied. Our model may be useful in identifying areas unsuitable for pygmy rabbits and it is a useful first step in identifying appropriate habitat for the pygmy rabbit, potentially throughout their range.
