Balancing Timber Production and Conservation in the Oregon Coast Range: an Examination of the Response by Birds and Bird-induced Ecosystem Services to Forest Management at Multiple Scales

Creator:: Harris, Scott H.
Abstract:: Society derives many critical and irreplaceable values from forests. With a growing global human population and rates of consumption, forests are under increasing pressure to provide all these values simultaneously. To meet societal demands for wood products, tree plantations are becoming increasingly common and are replacing native forests. Yet, forests...

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...

Does the Matrix Matter? Using Radio Frequency Identification (RFID) Technology to Examine Hummingbird Movements in Fragmented Tropical Landscapes

Creator:: Jackson, Evan R.
Abstract:: There is increasing evidence that the type of land cover surrounding remnant patches of native habitats (the ‘matrix’) can modify effects of landscape change on biodiversity; thus the traditional idea of dichotomous habitat and non-habitat following island biogeography theory is insufficient in complex landscapes. Matrix type can have dramatic influences...

Overstory Structure and Community Characteristics of Oregon Ash (Fraxinus latifolia) Forests of the Willamette Valley, Oregon

Creator:: Prive, Sean
Abstract:: As species of ash trees become increasingly threatened worldwide by exotic pests and pathogens, it is important to develop descriptions of their ecologies that help guide the conservation and restoration of forests in which they are a major component. Oregon ash (Fraxinus latifolia) is a dominant tree species in wetland...

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...

An examination of several methods of quantifying forest structure in headwater riparian forests of western Oregon

Creator:: Haxton, Zane A.
Abstract:: Headwater streams are generally small, first-order streams that can comprise up to 80% (by stream length) of the drainage network in mountainous areas of the Pacific Northwest. These streams are intimately connected with downstream reaches, serving as a source of sediment, woody debris, organic matter and nutrients. The surrounding forests...

Trophic cascades and large mammals in the Yellowstone ecosystem

Creator:: Painter, Luke E.
Abstract:: Reintroduction of wolves to Yellowstone National Park (YNP) in 1995-96 provided a rare opportunity to observe the response of an ecosystem to the return of a top predator, including possible reversal of decades of decline of aspen, cottonwood, and tall willows suppressed by intensive herbivory on elk winter ranges. To...

Urban Forests Role in Ecosystem Services in the 24:1 Community and the Normandy Schools Collaborative of St. Louis County, Missouri: A Study in Environmental Justice

Creator:: Templer, Amanda L.
Abstract:: The 24:1 Community is a growing community with ongoing concerns over historical residential segregation, minority-exposure to environmental hazards, and sparse tree canopy coverage. This paper presents a comprehensive review of the current state of the community’s urban forest through an assessment of the urban forest. It also highlights the need...

Potential effects of the invasive grass Ventenata dubia on elk habitat selection within the Starkey Experimental Forest and Range

Creator:: Crum, Keren-happuch R.
Abstract:: The invasive annual grass ventenata (Ventenata dubia) has become an increasing problem within western rangelands. Forage quality of areas infested with ventenata is reduced as its high silica content makes it unpalatable to livestock and wildlife. In the following study, I examined whether significant presence of ventenata affects habitat use...
