Table Top five most important variables for each Study Area – Season combination model with and without temperature covariates, measured by the mean decrease in Gini index (node impurity). The possible variables included temperature minimum, maximum, and difference (T­min, Tmax, Tdiff); topographic position index (TPI) and topographic heterogeneity index (THI) at scales of 50 m, 200 m, and 400 m; sagebrush patch core area index (CAI) and contiguity (CONTIG); distance to tree cover (TREEDIST); and density of tree cover (TREEDEN) within 400 m and 800 m.
