Drivers and Impacts of a Recent Annual Grass Invasion: Ventenata dubia and Fire in the Inland Northwest

Creator:: Tortorelli, Claire M.
Abstract:: Biological invasions threaten native biodiversity, alter ecosystem function, and are a major cause of economic losses across the planet. The most impactful invaders alter disturbance regimes and initiate state shifts to outside the historical range of variability of the ecosystem. Concern for ecological and economic losses has prompted a rapid...

Central Park's Woodlands: Forest Community Changes After a Decade of Management

Creator:: Hodges, Alexander R.
Abstract:: The woodlands of New York City's Central Park have seen varying levels of management and neglect since the creation of the park over 150 years ago. The Central Park Conservancy has aimed to restore, enhance, and elevate the stewardship of the park, including its woodlands and other Natural Areas, since...

Age structure, developmental pathways, and fire regime characterization of Douglas-fir/western hemlock forests in the central western Cascades of Oregon

Creator:: Tepley, Alan J.
Abstract:: Descriptions of the fire regime in the Douglas-fir/western hemlock region of the Pacific Northwest traditionally have emphasized infrequent, predominantly stand-replacement fires and an associated linear pathway of stand development, where all stands proceed along a common pathway until reset by the next fire. Although such a description may apply in...

Patterns of tree establishment and vegetation composition in relation to climate and topography of a subalpine meadow landscape, Jefferson Park, Oregon, USA

Creator:: Zald, Harold S. J.
Abstract:: The forest alpine tundra ecotone (FTE, also known as alpine treeline or subalpine parkland), is a conspicuous feature of mountain landscapes throughout the world. Climate change-driven increases in temperature are believed to result in FTE movement and tree invasion of subalpine meadows, which have been documented throughout the Northern Hemisphere...

Ecological Forestry : A Critical Analysis

Creator:: Batavia, Chelsea
Abstract:: Although science is widely accepted as a fundamental source of information underlying decisions about forest management and conservation, considerably less attention has been paid to the inevitable role that normative values and beliefs play in such decisions. This thesis highlights the normative dimensions of "ecological forestry," a strategy of forest...

Managing for climate change on federal lands of the western United States: perceived usefulness of climate science, effectiveness of adaptation strategies, and barriers to implementation

Creator:: Kemp, Kerry B., Blades, Jarod J., Klos, P. Zion, Hall, Troy E., Force, Jo Ellen, Morgan, Penelope, and Tinkham, Wade T.
Abstract:: Recent mandates in the United States require federal agencies to incorporate climate change science into land management planning efforts. These mandates target possible adaptation and mitigation strategies. However, the degree to which climate change is actively being considered in agency planning and management decisions is largely unknown. We explored the...

Created Snag Dynamics and Influence on Cavity-nesting Bird Communities over 25 years in Western Oregon

Creator:: Barry, Amy Marie
Abstract:: Snags provide critical habitat for nearly one-third of wildlife species in forests of the Pacific Northwest, so historic declines in snags are thought to have had a strong impact on biodiversity. Resource managers often create snags to mitigate the scarcity of snags within managed forests, but information regarding the function...

Tradeoffs and Synergies among Wild Ungulates, Early Successional Plant Communities and Management Intensification in Forest Plantations of the Oregon Coast Range

Creator:: Stokely, Thomas D.
Abstract:: As the global demand for natural resources increases, more land will be intensively managed for the production of commodities such as timber, with potential consequences to biodiversity, ecological functioning and ecosystem services provided to society. Although there is strong consensus that intensive land management practices can negatively affect biodiversity, less...

Mapping disturbance interactions from earth and space : insect effects on tree mortality, fuels, and wildfires across forests of the Pacific Northwest

Creator:: Meigs, Garrett W.
Abstract:: Given the vital role of forest ecosystems in landscape pattern and process, it is important to quantify the effects, feedbacks, and uncertainties associated with forest disturbance dynamics. In western North America, insects and wildfires are both native disturbances that have influenced forests for millennia, and both are projected to increase...

The Mountain Pine Beetle, Climate Change and Sustainable Forestry in the Northern Rocky Mountain

Creator:: Gillen, Amanda
Abstract:: Mountain pine beetles (MPB) have killed millions of acres of forest throughout the Rocky Mountain ecoregion in the United States and Canada and climate change may be intensifying outbreaks. Climate change can change forest ecosystems and dynamics by increasing drought conditions and intensifying heat waves. Due to changing climate conditions,...
