Modeling gray wolf habitat in Oregon using a geographic information system

Creator:: Larsen, Tad
Abstract:: Gray Wolves (Canis lupus) were once found throughout North America including Oregon. Wolves were extirpated from Oregon due to heavy hunting pressure in the late 19th and early 20th centuries and have been absent for over 50 years. Successful reintroduction efforts in Idaho and the greater Yellowstone area have caused...

Agriculture and wildlife : an economic analysis of waterfowl habitat management on farms in western Oregon

Creator:: Rasker, Ray
Abstract:: This study is a policy analysis of the incentives, including fee hunting, as a means to promote wildlife habitat development on private agricultural land. The management of habitat for migratory waterfowl in Western Oregon was investigated as a case study. Three separate analysis techniques were employed, presented as independent manuscripts....

Watershed councils and woodland owners : the Oregon experience

Creator:: Rickenbach, Mark G., 1968-
Abstract:: Oregon's watershed councils are local, non-regulatory, collaborative forums charged with the recovery of endangered salmon and improving water quality under The Oregon Plan for Salmon and Watersheds. Private forest landowners, given their prominence is owning riparian areas, are central to success of these efforts. Using a statewide survey of watershed...

Spatial analysis techniques for ensuring the compatibility of land management activities and aquatic habitat quality in eastern Oregon

Creator:: Bettinger, Pete, 1962-
Abstract:: A land management scheduling model is developed that uses a Tabu search procedure to schedule timber harvests and road management activities, while simultaneously meeting (over time and space) two aquatic goals, and also providing for an even-flow of timber harvest volume. Decision variables include land units and roads, and they...

An economic assessment of western Oregon's private forests with streamside management restrictions

Creator:: Schillinger, Randall R.
Abstract:: Management restrictions are simulated on streamside acres owned by private interests in western Oregon to assess forest inventory and log market implications. A dynamic, nonlinear optimization model of western Oregon's softwood log market simulates the resource and economic impacts of set-aside and minimum harvest age restrictions on forest acreage within...

Spatial and temporal distributions of western juniper in John Day Fossil Beds National Monument, Oregon

Creator:: Chen, Ya-Chian
Abstract:: Post-settlement juniper expansion in the western states has been reported for decades, including western juniper (Juniperus occidentalis Hook ssp. occidentalis) woodlands in the northwestern states. A 15 km2 study area in the Sheep Rock Unit of John Day Fossil Beds National Monument in eastern Oregon was selected to study spatial...

Oregon spotted frog (Rana pretiosa) habitat use and herbage (or biomass) removal from grazing at Jack Creek, Klamath County, Oregon

Creator:: Shovlain, Amie M.
Abstract:: We evaluated the effects of herbage removal from livestock grazing on Oregon spotted frog (Rana pretiosa) habitat use by monitoring frog locations in grazed and matched ungrazed treatments across a range of grazing intensities at Jack Creek, Fremont-Winema National Forest, Oregon. Thirteen cattle exclosures were deployed along Jack Creek in...

Using a heuristic programming method for incorporating wildlife habitat constraints into spatial harvest scheduling on the Elliott State Forest

Creator:: Lennette, Marie
Abstract:: The Elliott State Forest, located in the Coast Range of Oregon, is currently revising their Habitat Conservation Plan (HCP). Many of the constraints in the HCP are spatial, requiring identification of specific parcels in order to limit activity along habitat reserves, limit harvest opening size, and to coordinate activities within...

Forest and wildlife habitat analysis using remote sensing and geographic information systems

Creator:: Fiorella, Maria R.
Abstract:: Forest and wildlife habitat analyses were conducted at the H.J. Andrews Experimental Forest in the Central Cascade Mountains of Oregon using remotely sensed data and a geographic information system (GIS). Landsat Thematic Mapper(TM) data were used to determine forest successional stages, and to analyze the structure of both old and...
