Characteristics of forests at spotted owl nest sites in the Pacific Northwest

Creator:: Hershey, Kit
Abstract:: This study describes the composition and structure of forests within the immediate vicinity of Northern spotted owl (Strix occidentalis caurina) nest sites in the Klamath, Coast, and Cascade provinces of western Oregon and the Olympic province, Washington. I compared forest stand data collected at 105 nest sites with data from...

Activity of bats in thinned, unthinned, and old-growth forests in the Oregon Coast Range

Creator:: Humes, Marcia Lynn
Abstract:: Ten species of bats occur in the Oregon Coast Range and are hypothesized to be associated with late-successional forests. The development of characteristics of late-successional forests in young forest stands can be accelerated through silvicultural practices such as thinning I examined the effects of thinning on the use of forests...

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...

Nutritional ecology of cervids in old-growth forests in Olympic National Park, Washington

Creator:: Leslie, David M.
Abstract:: Nutritional ecology of unhunted and sympatric populations of Roosevelt elk, Cervus elaphus roosevelti, and Columbian black-tailed deer, Odocoileus hemionus columbianus, was investigated in old-growth forests of the Hoh Valley in Olympic National Park, Washington, from September 1979 to November 1981. Seasonal diets of both cervids generally were comprised of common...

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...

Foraging ecology of prairie falcons in northern California

Creator:: Haak, Bruce A.
Abstract:: Nine Prairie Falcons (Falco mexicanus) were radio-tagged in northern California during the spring and summer of 1976 and 1977 to study foraging behavior. The mean home range size for 3 males was 227.8 km²; largest portions of the home range were used during the incubation period. Shifts in foraging areas...

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...
