Small mammal and amphibian communities and habitat associations in red alder stands, central Oregon Coast Range

The authors did not detect differences between streamside and upland sites in 25 or 28 habitat characteristics, nor in capture rates for one amphibian species and four mammal species. Capture rates for Ensatina salamanders Ensatina eschschlotzi were higher in upland than in streamside habitats. Roughskin newts Taricha granulosa were the most common amphibian. The small mammal community was dominated by deer mice Peromyscus maniculatus, Trowbridge's shrews Sorex trowbridgii, Pacific shrews S. pacificus, and Virginia opossums Didelphis virginiana. Capture rates for five species were associated with the abundance of woody debris and/or vegetation on the sites. Alnus rubra stands should be considered important landscape components contribution to small mammal and amphibian diversity. -from Authors
