expected number of stations in a site with the species) among treatments for Peromyscus oreas, Clethrionomys gapperi, Sorex monticolus, Sorex trowbridgii, Tamiasciurus douglasii, and Glaucomys sabrinus.
While the relative importance of each factor varied by corridor and species, the degree of forest structure at, and immediately around, each site (as indicated by corridor width at a site and adjacent old-growth forest) was meaningful for several additional species including Clethrionomys gapperi, Glaucomys sabrinus, and Tamiasciurus douglasii.
For the two arboreal sciurids, Glaucomys sabrinus and Tamiasciurus douglasii, both large, downed trees and a complex vertical structure are important (Carey 1991, 1995, Ransome and Sullivan 1997), and are found throughout these corridors.
Finally, more traditional measures (isolation and corridor width) remained important; for example, relative densities of Peromyscus oreas, Sorex monticolus, and Tamiasciurus douglasii declined with increasing isolation of sites, and relative densities of Clethrionomys gapperi, Glaucomys sabrinus, and Tamiasciurus douglasii (albeit, in one corridor only) showed positive associations with corridor width.

In the Black Hills National Forest (BHNF), there is an isolated population of northern flying squirrel, Glaucomys sabrinus bangsi (Rhoads) (King, 1951; Wells-Gosling and Heaney, 1984) that is restricted to this region of western South Dakota.
