The long-term management of species at risk on military installations requires consideration of the direct and indirect effects of climate change. One of the direct effects will be change in the seasonal extents of home ranges of snakes, which can change the availability of food and their impact on prey animals. Therefore, forecasting differences in home range extents is useful for predicting changes in predator-prey relationships caused by climate change. This document describes a method for predicting home range sizes for the Eastern Indigo Snake, as a function of temperature and land cover. This approach could be used in future models developed to forecast population viability of snake populations and their prey.
