Human-eagle interactions on the lower Columbia River

Creator:: McGarigal, Kevin
Abstract:: During the past decade (1978-87), breeding success and productivity of bald eagles on the lower Columbia River (LCR) has been far below state and regional averages and well below levels required for delisting under the Endangered Species Act by the Pacific States Bald Eagle Recovery Plan. Human disturbance was suspected...

Disturbance and roosting ecology of California brown pelicans (Pelecanus occidentalis californicus) on East Sand Island in the Columbia River Estuary

Creator:: Wright, Sadie K.
Abstract:: The California brown pelican (Pelecanus occidentalis californicus) is listed as an endangered species under the U.S. Endangered Species Act. The Recovery Plan for this subspecies outlines the need to "Assure long-term protection of adequate food supplies and essential. . .roosting. . . habitat throughout the range." I investigated the effects...

Relative abundance and habitat associations of small mammals in two forest types in southern Oregon

Creator:: Johnston, Aaron N.
Abstract:: I studied small-mammal communities and their response to grazing in mixed-conifer forests and oak woodlands in the Cascade-Siskiyou National Monument in southern Oregon. My objectives were to (1) compare small-mammal communities among forest types and grazing intensities, (2) identify riparian affiliated species, and (3) describe microhabitat associations. Over two years,...

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...

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...

Survival, movements and habitat selection of pygmy rabbits (Brachylagus idahoensis) on the Great Basin of southeastern Oregon and northwestern Nevada

Creator:: Crawford, Justin A.
Abstract:: I investigated survival, movements, home range sizes, and habitat selection of pygmy rabbits (Brachylagus idahoensis) in southeastern Oregon and northwestern Nevada from June 2005 to June 2007. I trapped 298 rabbits on four sites and fitted each with radio transmitters. More than 13,000 locations of telemetered rabbits were recorded. I...

Demography and habitat selection of northern spotted owls in post-fire landscapes of southwestern Oregon

Creator:: Clark, Darren A.
Abstract:: Several large wildfires in southwestern Oregon during the summers of 2001 and 2002 provided the opportunity to investigate the impacts of wildfire on northern spotted owls (Strix occidentalis caurina). I used radio-telemetry and demographic surveys to describe demographic performance and habitat selection of spotted owls in the areas burned by...

Demography, home range, and habitat selection of northern spotted owls in the Ashland Watershed

Creator:: Schilling, Jason W.
Abstract:: Northern Spotted Owls (Strix occidentalis caurina) inhabit productive forests that historically supported frequent, large, variable-severity fires in the Klamath province of southwestern Oregon occur in complex. The potential for high-severity wildfire remains high throughout this region, so remaining spotted owl habitat is at risk. An adaptive management approach to fire...
