Arthropod communities on understory plants in thinned and unthinned Douglas-fir forests in the Oregon Coast Range

Creator:: Doolittle, Alyssa M.
Abstract:: This study assessed the effects of thinning on arthropod communities on understory plants in the Central Oregon Coast Range. Arthropods were sampled from five understory plants in five pairs of thinned and unthinned, young (50-80 yrs), managed Douglas-fir stands, from late May to mid-July of 1998. Vine maple (Acer circinatum),...

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,...

Response of arthropods to different intensities of thinning in Oregon

Creator:: Yi, Hoonbok
Abstract:: The process of silvicultural thinning has become very controversial recently with regards to fire protection and management for old-growth conditions and biodiversity. Therefore, an unthinned control stand and 3 different thinning intensities were examined for their effects on the abundance, species richness, and diversity of arthropods in thinning treatments of...

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...

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...

Habitat relationships of small terrestrial vertebrates and invertebrates in managed forests in the southern Oregon Cascades

Creator:: McDade, Kirsten Ayn
Abstract:: Silviculture systems that involve commercial thinning may provide higher quality wildlife habitat than traditional clearcut systems, yet such systems have not been vigorously tested. This prospective study examined forest floor animal abundance and habitat relationships under three different silviculture conditions: clearcuts, commercial thins, and uncuts. Eighteen stands, six per treatment,...

Bird-vegetation relationships across ten years after thinning in young thinned and unthinned Douglas-fir forests

Creator:: Yegorova, Svetlana
Abstract:: Bird-vegetation associations are a base for bird conservation and management, as well as for predictions of the effects of resource management and climate change on wildlife populations. A recent shift in forest management priorities from timber production to native species' habitat conservation on federal lands has emphasized the need to...

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...

An economic assessment of western Oregon's private forests with streamside management restrictions

Creator:: Schillinger, Randall R.
Abstract:: Management restrictions are simulated on streamside acres owned by private interests in western Oregon to assess forest inventory and log market implications. A dynamic, nonlinear optimization model of western Oregon's softwood log market simulates the resource and economic impacts of set-aside and minimum harvest age restrictions on forest acreage within...

The influence of forest management on headwater stream amphibians at multiple spatial scales

Creator:: Stoddard, Margo A.
Abstract:: To effectively manage for biodiversity at broad, ecosystem scales, the influences of habitat structure at multiple spatial scales on vertebrate species must be understood. There are few studies on the broad-scale habitat requirements of stream amphibians despite their importance in streams in forest ecosystems in the Pacific Northwest (PNW) as...
