The purpose of this research was to determine whether feedback
from vocational interest inventories leads to the arousal of psychological
reactance. The data for the study was collected from 80 male
and female subjects who were first year students at Oregon State University
enrolled in Psychology 111, Personal Development.

I evaluated fire occurrence, growth and recruitment and determined the fire history of 21 old and 20 young 8ha stands in Cascade, Siskiyou and mid-Coast mixed conifer and evergreen forests in southwestern Oregon. The rates and patterns of growth were measured and analyzed on 1,079 old-growth and 2,111
young stand...
The Applegate Fire Plan is a collaborative effort, hatched from an idea that was developed jointly by local citizens and federal agency folks in the Spring of 2001. Due to wide-spread participation throughout the Applegate Valley, general project coordination was organized by the Applegate Partnership, a non-profit communitybased group founded...
Two research questions are posed: (1) How have ecosystem conditions changed through time in southwestern Oregon? (2) How have culture-driven and climate-driven processes contributed to ecosystem change in southwestern Oregon? A brief introduction to the Little River study area is followed by a cultural and ecological history of the watershed....
Fire is the dominant disturbance process in western U.S. forests, and although effects of fire in upland forests are relatively well-studied, there is little information about fire effects on riparian forests, critical areas of the landscape for both habitat and water quality. This dissertation examines different aspects of fire effects...
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...
The 2002 Biscuit Fire burned through more than 200,000 ha of mixed conifer/
evergreen hardwood forests in southwestern Oregon and northwestern
California. The remarkable size of the fire and the diversity of conditions through
which it burned provided an opportunity to analyze the correlates of burn severity
across vegetation types...
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...
Descriptions of the fire regime in the Douglas-fir/western hemlock region of the Pacific Northwest traditionally have emphasized infrequent, predominantly stand-replacement fires and an associated linear pathway of stand development, where all stands proceed along a common pathway until reset by the next fire. Although such a description may apply in...
