Water vole populations were surveyed in the Big Horn Mountains of north central Wyoming to determine how livestock grazing affects their habitat. Voles were surveyed using a mark and recapture method in early summer and mid-summer in 2000 and 2001. Sites were either grazed by cattle in a rest-rotation system or were excluded from grazing. During the same time period as the vole surveys, streamside canopy cover and biomass were measured as well as site characteristics including stream water depth, elevation, precipitation, and temperature. These measurements were then used in a model to predict vole habitat.
