Evaluation of management alternatives for an undeveloped, forested area in Oregon's coast range

Creator:: Johnson, Kenneth Norman
Abstract:: One of the most vexing problems facing the United States Forest Service in Western Oregon concerns its management of undeveloped forested lands. Many of these areas contain highly productive timberland, and restriction of timber harvesting to preserve the land's primitive character can be very costly. Also there are conflicting pressures...

Shrub epiphyte communities in relation to stand management in forests of western Oregon

Creator:: Rosso, Abbey L.
Abstract:: This dissertation describes the epiphyte communities on tall shrubs in forests of western Oregon, with a focus on potential effects of management practices on these communities. Shrubs and other hardwoods have recently gained recognition as hotspots of diversity for epiphytes in young conifer forests of the region. Yet little is...

Contextual systems description of an Oregon coastal watershed

Creator:: Goetze, Brigitte
Abstract:: Many resource management controversies indicate disagreement about the possible intended and unintended effects of management actions on ecosystems. Researchers have documented a variety of negative effects on specific ecosystems, e. g. the degradation of salmonid habitat due to mass wasting (Hagans et al. 1986). While the effects of some management...

Applying random utility modeling to recreational fishing in Oregon : effects of forest management alternatives on steelhead production in the Elk River watershed

Creator:: Alexander, Susan J.
Abstract:: A random utility model of trip demand for steelhead fishing is constructed by using a logit regression technique and data from the 1990 Oregon Angler Survey, conducted by the Oregon Department of Fish and Wildlife. The model is formulated to estimate demand when only the regional destination is known. Results...

The economic consequences of intensifying forest management in Douglas County, Oregon

Creator:: Dippon, Duane R.
Abstract:: The objective of this study was to measure the consequences of alternative forest management intensification programs. These consequences include future harvest levels, silvicultural labor and capital requirements, and the income and employment generated directly and indirectly. The system utilizes the Timber Resource Economic Estimation System (TREES) model, a harvest scheduling...

Spatial analysis techniques for ensuring the compatibility of land management activities and aquatic habitat quality in eastern Oregon

Creator:: Bettinger, Pete, 1962-
Abstract:: A land management scheduling model is developed that uses a Tabu search procedure to schedule timber harvests and road management activities, while simultaneously meeting (over time and space) two aquatic goals, and also providing for an even-flow of timber harvest volume. Decision variables include land units and roads, and they...

Dead wood dynamics and relationships to biophysical factors, forest history, ownership, and management practices in the Coastal Province of Oregon, USA

Creator:: Kennedy, Rebecca S.H.
Abstract:: Dead wood patterns and dynamics vary with biophysical factors, disturbance history, ownership, and management practices. Through field and modeling studies, I examined the current and potential future amounts of dead wood in two landscapes and region-wide in the Coastal Province of Oregon. The objectives of the first study were to...

Functional relationships among songbirds, arthropods, and understory vegetation in Douglas-fir forests, western Oregon

Creator:: Hagar, Joan C.
Abstract:: Arthropods are important food resources for birds. Forest management activities can influence shrub-dwelling arthropods by affecting the structure and composition of understory shrub communities. Changes in abundance and species composition of arthropod communities in turn may influence the distribution and abundance of insectivorous birds. I examined relationships among bird abundance,...

Connecting local values and forest policy to the international forest sustainability dialogue

Creator:: Morré, Susan K.
Abstract:: Sustainable management of the world’s forests is a key component for conserving biodiversity, soil and water resources, mitigating climate change, strengthening economies, and promoting sustainable communities and human well-being, now and in the future. While international cooperation is important, the actual policies and management actions that affect forest conditions and...

Response of terrestrial vertebrates to three silvicultural treatments in the Central Oregon Coast Range

Creator:: Chambers, Carol Louise, 1958-
Abstract:: Growing concerns over maintaining animal and plant biodiversity have led to significant changes in forest management policies in the Pacific Northwest. Silvicultural alternatives to clear cutting are being suggested to promote development, retention, or creation of late-successional features such as large trees, multilayered canopies, snags and logs. As alternative management...
