Habitat Suitability Index Models: Southern red-backed vole (western United States)

Habitat preferences of the southern red-backed vole (Clethrionomys gapperi) are
described in this publication, which is one of a series of Habitat Suitability Index (HSI) models. A review and synthesis of the literature is followed by development of a model of the species-habitat requirements of the southern red-backed vole. Habitat suitability indexes are designed for use with Habitat Evaluation Procedures previously developed by the U.S. Fish and Wildlife Service.
