Late winter habitat selection by sheep in the Dawson region using resource selection functions (RSFs) built using sheep survey data collected 12-15 March 2009. These RSFs incorporated information on habitat types available to sheep, and those habitat types that sheep were observed using, and calculated relative probabilities of use by sheep for the entire study area. Of the candidate models, the bestsupported model showed that sheep selected for areas with high elevation, high convexity, high ruggedness and a southerly aspect, and selected against areas distant from escape terrain and with northerly aspects. Model validation using k-fold cross-validation showed that this RSF model accurately predicted late winter habitat selection by sheep in the Dawson region.
