Bull Run Reserve was used as a case study of conflicts
in management. The Bull Run Watershed supplies the Portland
Metropolitan area with its water. Conflicting goals led to
various management decisions. Sustained yield logging was allowed
within the watershed. Concern that continued logging
would lead to increased turbidity and...
North American beavers (Castor canadensis) are ecological engineers that improve biodiversity and can improve the health of riparian ecosystems. Beavers are generalist herbivores with some evidence of species preference, utilizing woody material for both food source and dam construction. In the South Slough National Estuarine Research Reserve, Charleston, Oregon, a...
Designation of areas as marine wilderness has been proposed as a strategy for managing the increasing threats facing the world’s oceans. Although social factors influence marine protected area success, the human dimensions of marine wilderness remain minimally explored. This thesis examines views of marine wilderness expressed by a representative sample...
Protected area creation, including creation of marine reserves (MRs), is increasingly molded by ecosystem based management (EBM) that integrates biological and social information in the pre and post establishment phases. Collecting social data from large and representative samples of the public (as opposed to other stakeholder groups) before establishing a...
Understanding the mechanisms of disease in forest pathology is a critical component to learning how to most efficiently manage tree diseases like Swiss needle cast (SNC). SNC is an economically important, fungal disease of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) that is prevalent in coastal areas of the Pacific Northwest. This...
The Timber Resource Analysis System (TRAS) was the
timber supply projection model used in conjunction with
the Timber Assessment Market Model (TAMM) to predict
future U.S. softwood timber harvests, inventories and
product prices in the 1980 RPA Timber Assessment conducted
by the USDA Forest Service. Several criticisms of the
TRAS...
Numerous development projects are implemented in developing countries to attain economic and ecological development. However, in most cases, the encouraging results observed during the implementation phase terminated with the project period, raising concerns on these projects' sustainability after the project period has ended. This study focuses on this sustainability issue...
Forest management has been influenced by many social and political changes, and one of the most prominent is the increasing urbanization of neighboring lands. As a result, forests once relatively far removed from urban areas now share boundaries with residential developments, and receive increasing pressure to provide recreation and other...
Satellite imagery has been a useful tool in monitoring land cover changes, including changes within protected areas. In the 1980’s and 1990’s Honduras created over 100 protected areas, yet few resources have been dedicated to their management. This study used Landsat satellite imagery to evaluate deforestation in the Río Plátano...
