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 ...
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 the extent to which scientific and technical information influences the revision of policy beliefs. ...
Predator species identification from saliva at kill sites with limited remains
Kill site investigations can provide valuable data about elusive predator species and predator-prey interactions for wildlife scientists and managers alike. However, the predator species must be definitively identified as the one responsible for the predation event. The traditional method of visually analyzing prey remains ...
Measuring Economic Value of Native American Cultural Designs within the Tribal Gift Box Market and Tribal Forest Certification
Many companies use Native American names, image and art designs in order to market their products, even though some of them have no affiliation with Native American tribes. This suggests Native American image and design provide a set of values for certain consumers. The purpose of this study is to help Native American tribal ...
Developing an Impact Assessment of Local Air Quality as a Result of Biomass Burns
Forest operations in the Pacific Northwest produce a large amount of harvest residues, known as harvest slash, commonly collected, piled and burned in prescribed fires. These prescribed slash burns provide a source of emissions, which affect local and regional air quality with potential negative impacts on human health. While ...
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, ...
Salicaceae Endophytes: Growth Promotion Potential in Rice (Oryza sativa L.) and Maize (Zea mays L.) and Bio-Control of Plant Pathogen
Abstract Salicaceae plants; poplar (Populus trichocarpa) and willow (Salix sitchensis) are hosts of many endophyte species. Salicaceae endophytes colonize the plant endosphere and confer various growth benefits to host plants. First three studies were conducted focusing on how these endophytes colonize and support the growth ...
The invasion risk in the Pacific Northwest of two closely related grass species in the Genus Cortaderia
The distribution of Cortaderia selloana and Cortaderia jubata in the Pacific Northwest (PNW) has not been examined on a regional scale although geospatial information exists. Cortaderia selloana continues to be sold in nurseries across Oregon and Washington and both species are used as landscape plantings. With invasive ...
Examining Factors Affecting Attitudes toward Nuclear Power in Taiwan
Nuclear power has become a major issue in Taiwan for several decades. The objective of the present study is to obtain evidence about the major determinants contributing to attitudes toward nuclear power, by investigating socioeconomic factors, environmental attitudes, knowledge of issues, trust, and risk perception, in shaping ...
