Optimizing forest management in consideration of environmental regulations, economic constraints, and ecosystem services
(2014-02-24)Forest management is a multi-objective problem. Managers must plan treatments and harvests while accounting for multiple factors such as environmental regulations, economic and silvicultural constraints, and ecosystem ... -
Optimizing Management Guidelines for the Non-Native Azalea Lace Bug on Rhododendron Species in Western Washington
The non-native, invasive azalea lace bug, Stephanitis pyrioides (Scott), is one of the most serious insect pests of the genus Rhododendron, especially evergreen azaleas, an especially popular subgenus of Rhododendron. ... -
Ownership patterns drive multi-scale forest structure patterns across a large landscape in southern coastal Oregon, USA
Globally, the physical structure of forests results from their environmental setting, disturbance history, and human management practices. Human management practices today arguably have the greatest impact on the types and ... -
The papermaking properties of Washington State wheat straw
(1999)Current environmental and social pressures are limiting wood harvest from U.S. public forest land. As a byproduct of the cereal grain industry, wheat straw may also be used for papermaking. However, studies of wheat straw ... -
Parasitic plants and community composition: how Castilleja levisecta affects, and is affected by, its community
Parasitic plants are native to many ecosystems around the world. Their effects on their environment are not always negative, and in some cases their presence can increase diversity in an ecosystem. We used Castilleja ... -
Patterns and drivers of conifer regeneration following stand-replacing wildfire across western Cascadia
Tree regeneration is a critical mechanism of forest resilience to stand-replacing wildfire. Post-fire tree regeneration dynamics have been relatively well-studied in historically fire-frequent forests across western North ... -
Patterns and processes in tropical forests: an analysis of forest structure and function from long-term permanent plots in Venezuela, Northern South America
The differential responses of trees to climate and resource gradients, coupled with historical and current disturbances affect forest dynamics and creates complex landscape patterns in forest assemblages and structures. ... -
Perceived Impacts of Climate Change on Forests and Livelihoods in the Padampokhari Village on the Parsa Wildlife Reserve Buffer Zone, Nepal
Livelihoods in rural communities in Nepal depend on the condition of local natural resources. Rural communities are especially vulnerable to climate change because of their ecological fragility and economic marginality, ... -
Phalaris arundinacea control and riparian restoration within agricultural watercourses in King County, Washington
(2008)Phalaris arundinacea (reed canarygrass) is one of the most aggressive and challenging invasive species within wetlands of the Pacific Northwest. This invasive typically dominates a site, producing a monoculture, reducing ... -
Physiological Responses of Himalayan Blackberry (Rubus armeniacus Focke) to Flooding and Implications for Wetland Restoration in the Pacific Northwest
(2013-02-25)Himalayan blackberry (Rubus armeniacus Focke) is a common invader of anthropogenically disturbed wetlands in the Pacific Northwest. Understanding of the plant's physiological response to inundation and associated anoxic ... -
Phytoremediation of Chlorpyrifos Insecticide: The Use of Woody Plants and Transgenics to Enhance and Understand the Uptake, Translocation, and Transformation of Chlorpyrifos
(2014-02-24)Poplar and willow trees have a significant ability to take up CPS and to translocate/degrade it within the plants and thus, assist in removing it from the hydroponic solution. To our knowledge, the poplar and willow species ... -
Pileated Woodpecker Occupancy and the Occurrence and Recruitment of Key Habitat Attributes in a Managed Forest
University of Washington Abstract Pileated Woodpecker Occupancy and the Occurrence and Recruitment of Key Habitat Attributes in a Managed Forest Amber Mount Chair of Supervisory Committee: PhD John M. Marzluff School of ... -
Planning for current species distributions is more effective than planning for nature’s stage in the face of climate change
Climate change poses a significant threat to biodiversity. Increasing the number and size of protected areas is one of the most frequently cited approaches to addressing this threat. However, because climate change is ... -
Planning for small forest landscapes: facilitating the connection between people and nature
(2013-07-25)A significant area of forest land in the United States is held by a diverse group of people known by the US Forest Service as family forest owners. Surveys reveal that family forest owners own forest land for a variety of ... -
Plot level comparative Global Warming Mitigation Potential analysis of Red Alder Wood & Douglas fir in the Pacific Northwest
Working forests help remove CO2 from the atmosphere, and when the trees from these forests getharvested, some of that sequestered carbon pass on to harvested wood products. Wood products produced from sustainably harvested ... -
Policy Implementation in Collaborative Watershed Management: A Multi-Case Study of Collaborative Efforts under Washington’s Watershed Planning Act
In many parts of the world, collaborative watershed management has become a common approach for place-based water resource governance. This study examined four local-scale collaborative watershed planning efforts that ... -
POLICY INTERVENTIONS IN INDIA TO IMPROVE COASTAL RISK REDUCTION IN THE FACE OF CLIMATE CHANGE
Coastal zones are one of the most dynamic natural ecosystems of our planet. The survival and livelihoods of coastal communities are contingent on the ecosystem services that coastal zones provide. Primary among these ... -
Policy-Oriented Learning Among National Forest Stakeholders in the Pacific Northwest: Changes in Policy Beliefs Since Adoption of the Northwest Forest Plan
This study evaluates whether national forests stakeholders in the Pacific Northwest region of the United States have changed their national forest policy beliefs since adoption of the 1994 Northwest Forest Plan, and describes ... -
