Abstract
We compared species composition and relative abundance of small mammals between riparian and upland habitats among five seral stages in the Coast Range of Western Oregon to determine the significance of these areas to different species. Riparian- and upland-associated species were identified based on capture frequencies from pitfall trapping. Species richness was similar between stream and upland habitats and among the five seral stages. However, there were significant differences in the abundances of nine small mammal species among seral stages. Total captures were highest in deciduous stands and progressively lower from shrub to old-growth coniferous forests. Neurotrichus gibbsii, Sorex bendirii, Sorex pacificus, Microtus longicaudus, Microtus townsendii, Phenacomys albipes, and Zapus trinotatus were captured in significantly higher numbers in riparian than in upland habitats. S. pacificus and M. longicaudus should be considered riparian associated species; S. bendirii should be considered an obligate species of riparian habitat. In contrast, Clethrionomys californicus showed a strong association with upland habitat. Our results indicate that small (second- third- and fourth-order) riparian systems and adjacent upland areas provide important habitat for small mammals on the Oregon Coast Ranges. Conservation plans of these riparian systems should consider these species as important components of these ecosystems
