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...

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...

Post-hatching survival and productivity of American avocets at drainwater evaporation ponds in the Tulare Basin, California

Creator:: Marn, Carolyn M. (Carolyn Mary), 1962-
Abstract:: Evaporation ponds that dispose of agricultural drainwater provide attractive habitat for waterbirds but may result in contaminant exposure that impairs reproduction. I estimated post-hatching survival and evaluated productivity estimates for American avocets (Recurvirostra americana) nesting at evaporation ponds in the Tulare Basin, California from 1991 to 1993. Avocets and Black-necked...

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...

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...

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...

Local weather, regional climate, and population dynamics of northern spotted owls in Washington and Oregon

Creator:: Glenn, Elizabeth M.
Abstract:: Since the early 1990s, declines in northern spotted owl (Strix occidentalis caurina) populations have been documented through extensive field surveys and range-wide demographic analyses. Although loss of late-successional forest has been credited as the primary cause for spotted owl population declines, environmental variation has also been shown to influence vital...
