Habitat use and densities of cavity-nesting birds in the Oregon Coast Range

Creator:

Nelson, S. Kim

Abstract:

I studied abundance patterns and habitat use of eight cavitynesting bird species in the Coast Ranges of Western Oregon during the spring and summer of 1985 and 1986. Three age classes of unmanaged Douglas-fir (Pseudotsuga menziesii) stands were selected for study: young (40-80 yrs), mature (80-200 yrs), and old-growth (>200...

Roosevelt elk habitat use in the Oregon Coast Range

Creator:

Pope, Michael D. (Michael Dickens)

Abstract:

Few studies have evaluated non-migratory Roosevelt elk (Cervus elaphus roosevelti) interactions and habitat use on lands undergoing extensive timber removal. We captured and radio-tracked for 14 months representatives from 29 different bands of elk across a 37,000 ha area of Oregon's Coast Range. We identified 6 habitat variables within individual...

Small-mammal herpetofauna abundance in riparian and upslope areas of five forest conditions

Creator:

Gomez, Douglas M.

Abstract:

I compared species composition and relative abundance of'small mammals and herpetofauna between riparian and upslope habitats among 5 forest types. Riparian- and upslope- associated species were identified based on capture frequency. Small mammal species richness was similar between stream and upslope habitats and among the 5 forest types. There were...

Influence of limited access roads on Roosevelt elk in the Oregon Coast Range

Creator:

Cole, Eric K.

Abstract:

No studies have evaluated the effects of limited vehicle access on movements, survival and habitat use of Roosevelt elk (Cervus elaphus roosevelti) . We installed twenty gates, restricting motorized vehicle access by the public in seven discrete Road Management Areas (RMAs), comprising 35% of the study area. We radio-tracked 31...
