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