Effects of spatial scale and heterogeneity on avian occupancy dynamics and population trends in forested mountain landscapes

Creator:: Frey, Sarah J. K.
Abstract:: Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...

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...

The use of burned forest by breeding birds following the Biscuit Fire in southwest Oregon

Creator:: Donaghy Cannon, Michelle M.
Abstract:: Fire severity is hypothesized as an important driver of bird responses to wildfire. For those species that typically respond negatively to increasing severity, Accessibility of high-severity burned forest may be dependent on the proximity of unburned or low-severity burned forest to meet all of the needs of breeding bird species...

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...

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...

Snag longevity, bird use of cavities, and conifer response across three silvicultural treatments in the Oregon Coast Range

Creator:: Walter, Scott T.
Abstract:: In the interest of meeting multiple forest management goals that include maintenance of wildlife, particularly cavity-nesting birds, uneven-aged silvicultural treatments are used increasingly in the Pacific Northwest. However, questions remain regarding the responses of cavity-nesting birds and residual green trees to different harvest intensities and patterns. To study these issues,...

Forest canopy sturcture in western Oregon : characterization, methods for estimation, prediction, and importance to avian species

Creator:: Fiala, Anne C. S.
Abstract:: Characterization of canopy structure, the horizontal and vertical distribution of the tree crowns in a forest, is important for the management of forests in the Pacific Northwest. The canopy is an important habitat element for many wildlife species, canopy structure affects understory development, and influences various natural processes, such as...

Cavity resources in Oregon white oak and Douglas-fir stands in the mid-Willamette Valley, Oregon

Creator:: Gumtow-Farrior, Daniel L.
Abstract:: Previous studies of bird communities in the mid-Willamette Valley, Oregon, indicated that Oregon white oak (Ouercus garryana) stands supported more cavity-using bird species than sympatric stands of Douglas-fir (Pseudotsuga menziesii). Mature Oregon oak stands are being harvested and few are regenerating. I compared cavity availability for hole-using fauna among 10...

Songbird populations of precommercially thinned and unthinned stands of ponderosa pine in east-central Washington

Creator:: Putnam, Betsy June
Abstract:: Populations of breeding birds and forest composition and structure were examined in preconimercially thinned and unthinned ponderosa pine (Pinus ponderosa Laws.) stands in east-central Washington. Stands were composed of predominantly ponderosa pine with a multi-aged structure made up of small even-aged clumps. Thinning reduced the density and foliage volume of...
