Land cover at northern spotted owl nest and non-nest sites, east-central Coast Ranges, Oregon

Creator:

Perkins, John P.

Abstract:

This study examined the differences, at various scales, between northern spotted owl (Strix occidentalis caurina) nest sites and non-nest sites, i.e., sites where no nests were found during surveys, in the Coast Ranges of Oregon. I compared land cover around 41 owl nest sites (ONS) and 41 non-nest sites (NNS)...

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...

Age-specific and lifetime reproductive success of known age Northern Spotted Owls on four study areas in Oregon and Washington

Creator:

Loschl, Peter J.

Abstract:

Northern Spotted Owls (Strix occidentalis caurina) are a long-lived forest owl and range-wide declines in their numbers have resulted in the species being listed as threatened under the endangered species act. While many studies have been focused on population trends and reproductive performance of Spotted Owls from different age-classes, none...

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...

Competitive interactions and resource partitioning between northern spotted owls and barred owls in western Oregon

Creator:

Wiens, J. David

Abstract:

The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted...

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...

Dispersal of juvenile northern spotted owls in western Oregon

Creator:

Miller, Gary Scott

Abstract:

Dispersal of juvenile northern spotted owls (Strix occidentalis caurina) was studied in western Oregon from 1982-1985. The study was initiated to document the pattern of juvenile spotted owl dispersal, survival, habitat use, and possible effects of forest fragmentation on the dispersing juveniles in the Pacific Northwest Douglas-fir Region. Forty-eight juveniles...
