Predicting habitat suitability for wildlife in southeastern Arizona using Geographic Information Systems: scaled quail, a case study

Abstract

Studies have used Geographic Information Systems (GIS) to evaluate habitat suitability for wildlife on a landscape scale, yet few have established the accuracy of these models. Based on documented habitat selection patterns of scaled quail (Callipepla squamata pallida), we produced GIS covers for several habitat parameters to create a map of potential habitat in southeastern Arizona. We found scaled quail coveys on 36% of surveys conducted inside of potential scaled quail habitat, and 80% of the scaled quail coveys found occurred within the potential habitat map. We developed a logistic regression model that predicted 70% of used and unused sites. Potential causes for the low accuracy of GIS models are discussed.
