The Community Economic Impacts Of Large Wildfires: A Case Study From Trinity County, California, Emily Jane Davis, Cassandra Moseley, Max Nielsen-Pincus, Pamela J. Jakes Jun 2014

The Community Economic Impacts Of Large Wildfires: A Case Study From Trinity County, California, Emily Jane Davis, Cassandra Moseley, Max Nielsen-Pincus, Pamela J. Jakes

Environmental Science and Management Faculty Publications and Presentations

Wildfires are increasing in severity and frequency in the American West, but there is limited understanding of their economic effects at the community level. We conducted a case study of the impacts of large wildfires in 2008 in Trinity County, California, by examining labor market, suppression spending, and qualitative interview data. We found that the 2008 fires had interrelated effects on several economic sectors in the county. Labor market data indicated a decrease in total private-sector employment and wages and an increase in public-sector employment and wages during the summer of 2008 compared to the previous year, while interviews captured …


Informal Trails And The Spread Of Invasive Species In Urban Natural Areas: Spatial Analysis Of Informal Trails And Their Effects On Understory Plant Communities In Forest Park, Portland, Oregon, Jill Elise Van Winkle May 2014

Informal Trails And The Spread Of Invasive Species In Urban Natural Areas: Spatial Analysis Of Informal Trails And Their Effects On Understory Plant Communities In Forest Park, Portland, Oregon, Jill Elise Van Winkle

Dissertations and Theses

The risk of spread and establishment of invasive species to interior habitat within urban parks is of great concern to park managers and ecologists. Informal trails as a vector for this transmission are not well understood. To characterize effects of informal trails on understory plant communities, I conducted a study of the informal trail network in Forest Park, Portland, Oregon. The system of 382 informal trails was mapped and evaluated qualitatively, and from this population a systematic sample was selected for analysis. To identify hotspots of informal trail activity, showing the relationship of informal trails to formal trails, other park …


The Effectiveness Of Forest Collaborative Groups At Reducing The Likelihood Of Project Appeals And Objections In Eastern Oregon, Brent M. Summers Apr 2014

The Effectiveness Of Forest Collaborative Groups At Reducing The Likelihood Of Project Appeals And Objections In Eastern Oregon, Brent M. Summers

Environmental Science and Management Professional Master's Project Reports

Collaborative planning has been used as a tool to address wicked natural resource conflicts and engage those affected by federal land management agency decisions. The United States Forest Service (USFS) is mandated by law to involve the public on project-level planning. In Oregon, Forest Collaborative Groups have been engaging with the USFS to involve stakeholders who are concerned with the activities on National Forests. It is widely believed that these groups are reducing project-level appeals and objections (appeals); however, there is no empirical evidence to validate these beliefs. National Environmental Protect Act (NEPA) document data were collected from the USFS …


Climate Change Effects On Northern Great Lake (Usa) Forests: A Case For Preserving Diversity, Matthew Joshua Duveneck, Robert M. Scheller, Mark A. White, Stephen D. Handler, Catherine Ravenscroft Feb 2014

Under business as usual (BAU) management, stresses posed by climate change may exceed the ability of Great Lake forests to adapt. Temperature and precipitation projections in the Great Lakes region are expected to change forest tree species composition and productivity. It is unknown how a change in productivity and/or tree species diversity due to climate change will affect the relationship between diversity and productivity. We assessed how forests in two landscapes (i.e., northern lower Michigan and northeastern Minnesota, USA) would respond to climate change and explored the diversityproductivity relationship under climate change. In addition, we explored how tree species diversity …


Managing For Resistance And Resilience Of Northern Great Lakes Forests To The Effects Of Climate Change, Matthew Joshua Duveneck Jan 2014

Managing For Resistance And Resilience Of Northern Great Lakes Forests To The Effects Of Climate Change, Matthew Joshua Duveneck

Dissertations and Theses

Climate change is expected to drastically change the environmental conditions which forests depend. Lags in tree species movements will likely be outpaced by a more rapidly changing climate. This may result in species extirpation, a change in forest structure, and a decline in resistance and resilience (i.e., the ability to persist and recover from external perturbations, respectively). In the northern Great Lakes region of North America, an ecotone exists along the boreal-temperate transition zone where large changes in species composition exist across a climate gradient. Increasing temperatures are observed in the more southern landscapes. As climate change is expected to …


The Design And Use Of Forest Decision Support Systems In The Usa, Sean N. Gordon, Keith M. Reynolds Jan 2014

The Design And Use Of Forest Decision Support Systems In The Usa, Sean N. Gordon, Keith M. Reynolds

Institute for Sustainable Solutions Publications and Presentations

Computer-based tools for supporting forest management. The experience and the expertise world-wide answers a call from both the research and the professional communities for a synthesis of current knowledge about the use of computerized tools in forest management planning. According to the aims of the Forest Management Decision Support Systems (FORSYS) (http://fp0804.emu.ee/) this synthesis is a critical success factor to develop a comprehensive quality reference for forest management decision support systems.

The emphasis of the book is on identifying and assessing the support provided by computerized tools to enhance forest management planning in real-world contexts. The book thus identifies the …


Impacts Of Fire And Climate Change On Long-Term Nitrogen Availability And Forest Productivity In The New Jersey Pine Barrens, Melissa S. Lucash, Robert M. Scheller, Alec M. Kretchun, Kenneth L. Clark, John Hom Jan 2014

Increased wildfires and temperatures due to climate change are expected to have profound effects on forest productivity and nitrogen (N) cycling. Forecasts about how wildfire and climate change will affect forests seldom consider N availability, which may limit forest response to climate change, particularly in fire-prone landscapes. The overall objective of this study was to examine how wildfire and climate change affect long-term mineral N availability in a fire-prone landscape. We employed a commonly used landscape simulation model (LANDIS-II) in the New Jersey Pine Barrens, a landscape characterized by frequent small fires and fire-resilient vegetation. We found that fire had …
