Habitat use by cavity-nesting birds in young thinned and unthinned Douglas-fir forests of western Oregon

Creator:: Weikel, Jennifer M.
Abstract:: There is limited information on how to manage young forests of the Pacific Northwest to benefit wildlife populations. Commercial thinning is becoming more important in young forests both as a tool for timber management and to hasten the development of old-forest characteristics. There is some evidence that many species of...

Diversity and abundance of birds across a hardwood gradient in early seral Douglas-fir plantations

Creator:: Ellis, Tana M.
Abstract:: Recent evidence suggests that population declines of some avian species may be driven primarily by reduced quantity and diversity of early-successional habitat on the breeding grounds. Increasing intensity of forest management on private lands and decreased harvest rates on federal lands has resulted in a loss of the diverse early-successional...

Bird communities in managed conifer stands in the Oregon Cascades : habitat associations and nest predation

Creator:: Vega, Robyn M. S.
Abstract:: Green-tree retention is being implemented on state and federal lands in Oregon. Silvicultural prescriptions with tree and snag retention are thought to mimic natural disturbance patterns in the Pacific Northwest more closely than traditional silvicultural practices, which reduce structural complexity. The effects of green-tree retention on native bird species in...

Influences of salvage logging on forest birds after fire in the eastern Cascades, Oregon

Creator:: Cahall, Rebecca E.
Abstract:: Previous research examining the influences of post-fire salvage logging on abundances of birds has focused primarily on the response of cavity-nesting species. There is limited research in regard to the impact of salvage logging on a broader range of bird species. In addition, little is known about how different intensities...

Effects of streamside riparian forest management on Ephemeroptera and Trichoptera community structure in four western Oregon streams

Creator:: Walsh, Jennifer B. S.
Abstract:: In order to restore conifers in hardwood dominated riparian forests 25% of the experimental reach forests alongside four streams in western Oregon was clearcut. Clearcutting removed 400 m without residual buffers from a 1600-m streamside forest reach in patchcuts spanning 100 and 200 meters. To assess the cumulative and direct...

The effects of silvicultural activities on wildlife and fish populations in Oregon and the Pacific Northwest : an annotated bibliography from 1960-1999

Creator:: Maas-Hebner, Kathleen G. (Kathleen George), Schrader, Barbara A., and Oregon State University. Forest Research Laboratory
Abstract:: This annotated bibliography was compiled to provide forest managers with a comprehensive list of sources on the potential effects of silvicultural activities on wildlife and fish populations in Pacific Northwest forests. The bibliography emphasizes publications directly examining silvicultural activities and responses by these populations. Abstracts from 296 publications are indexed...

Habitat associations of bird communities in shrub-steppe and western juniper woodlands

Creator:: Reinkensmeyer, Daniel P.
Abstract:: The encroachment of western juniper into mountain big sagebrush plant communities and the subsequent development of juniper stands results in significant changes in vegetation structure and complexity. This study described and compared vegetative structure and bird community measures among four cover types representing a broad range of structural stages among...

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...

Response of avian communities to herbicide-induced vegetation changes, western Oregon

Creator:: Morrison, Michael L.
Abstract:: The relationships between avian community structure and herbicide modification of vegetation were analyzed on early-growth clearcuts in western Oregon that had received phenoxy herbicide treatment 1 or 4 years previously. Only minor effects of herbicide treatment were evident 1-year after spraying, except for red adler (Alnus rubra), which still exhibited...

Avian communities in relation to habitat influenced by fire in a sagebrush steppe landscape

Creator:: Noson, Anna C.
Abstract:: Fire suppression in high-elevation sagebrush steppe over the last century has profoundly influenced the structure and complexity of vegetation communities. Although fire is the primary management tool used to restore these areas, the impact of this management practice on associated avian communities is poorly understood. We examined patterns of habitat...
