Soil Influence on Forest Vegetation Productivity and Patterns in the Eastern Cascades of Southern Oregon
Soils influence vegetation and can critically affect forest restoration results. Areas with similar parent materials can have changes in soil and vegetation across a slope, aspect, slope position, microtopography, and elevation. The objective of this project was to assess what soil characteristics influence vegetation ...
Cost-Efficient Spatial Placement of Water Retention Sites (WRS) to Reduce Sediment in Le Sueur River Watershed,MN
Since the widespread European settlement, the Minnesota River Basin has undergone dramatic changes in hydrology. The resulting increases in streamflows and the erosion of near-channel features contribute a large amount of sediment to the downstream rivers. In spite of some hydrologic alterations caused by climate change, ...
Stem and Branch Diameter Response in Pruned Douglas-fir Plantations (Pseudotsuga menziesii var. menziesii): Implications for Volume and Clear Wood Production in the U.S. Pacific Northwest
Enhancement of timber quality from self-pruning in Douglas-fir stands typically begins to occur around 60-80 years of age. Due to 40-year rotations in production settings, this species has the potential to benefit from the silvicultural treatment of pruning. Previous literature indicates that pruning may increase overall ...
Role Ambiguity and Perceived Organizational Politics in Wolf Recovery: Washington State Wildlife Agency Personnel Perspectives
Wolf recovery in Washington (WA) State provokes contentions amongst stakeholders: livestock owners, environmental groups, government organizations, and the public. Wolf recovery in WA also incites internal disputes and strains working relationships within state government entities charged with wolf management. These divisions ...
Volunteer Geographic Information Reporting System: A Cross-Case Comparison
Collaborating with volunteers to collect spatial information for environmental monitoring has been thought to be a socially-oriented mechanism for improving public participation and environmental decision-making when lacking sufficient managerial resources. Unlike general volunteer geographic information that initiates from ...
Landscape vegetation change, pattern detection, and interpretation in a subalpine fir forest infested with balsam woolly adelgid
Invasive insects and pathogens, climate change, and anthropogenic factors are causing broad-scale change in forest ecosystems. Identifying, understanding, and maintaining historic and functioning ecosystems in changing landscapes can be challenging because multiple internal and external factors interact across scales. In this ...
Social Capital in Marine Management Collaborative Networks: Lessons learned in the Coral Triangle and the Philippines
There has been a recent proliferation of collaborative ecosystem management approaches that create interlinked individuals working together to address socio-ecological problems. In these collaborative networks, through cooperating toward shared goals, participants create and maintain relationships, build trust, and share ...
Motivational Goals of Seattle Homeowners Related to Their Yards: Implications for Ecosystem Service Assessments and Behavioral Appeals
Nearly half of the land areas of many U.S. cities is zoned for single family residences (e.g., 49% of Seattle). These are fragmented management landscapes -- large numbers of parcels are individually managed yet collectively comprise substantial portions of local ecosystems. Promoting the health of urban ecosystems therefore ...
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 developed Watershed Management Plans under Washington State’s Watershed Planning Act of 1998. These efforts ...
Improving Forest Conservation in Frontier Environments: A Global Review and Case Studies from the Peruvian Amazon
The global conservation of intact forest ecosystems has been recognized as an important goal due to the many benefits they provide to people and biodiversity conservation. Despite their importance however, intact forest ecosystems continue to be cut and degraded globally at an unsustainable level. To improve the policies and ...
