Habitat
Habitat generalists inhabiting a variety of habitats, especially forest, woodland, and shrub habitats (MacDonald and Cook 2009). Prefers cool, mesic old-growth or second-growth deciduous, coniferous, or mixed forests, especially areas with large amount of ground cover. Regardless of forest type, voles favor mesic habitats and moist micro-environments. Muskegs and associated scrub and mixed-conifer forests of southeastern Alaska are not likely to support breeding populations of C. gapperi, however, black spruce (Picea mariana) peatlands of boreal forest apparently do support viable populations (Smith and Nichols 2004).
