Klaus et al. looked at the effects of cattle grazing on water vole population numbers and composition in the Beartooth mountains of Montana and Wyoming. Capture success of voles/1000 m of stream was greater on the ungrazed sites, while reproductively active females, for all age classes and weight of class I females, were greater on grazed sites. Cattle and sheep grazing in this area seemed to have little effect on the presence of water voles. The authors noted that a study by Luce (1995) found that moderate grazing did not exclude water voles, but under heavy grazing, the streambank did preclude water voles in that area.
