- Historically, Anglo Americans have been the primary clientèle at nature-based outdoor recreation areas in the United States (Chavez 2001, Dunn et al. 2002). Goldsmith (1 994) highlighted the lack of racial and ethnic diversity among National Park visitors. Citing a Texas A&M study, Goldsmith (1994) reported that less than 1 % of car visitors to Yosemite National Park were African American and less than 4% of bus riders to the park were African American. Visitation by Hispanics at Grand Canyon National Park in Arizona was similar to that for Blacks. Natural resource managers and policy...AuthorsCassandra Johnson Gaither, D.B.K EnglishSourceIn: Kruger, Linda E.; Mazza, Rhonda; Lawrence, Kelly, eds.

- Research interest in the forests of Oregon and Washington east of the Cascade Range can be traced back to 1897, when Fredrick V. Coville of the Division of Forestry, U.S. Department of Agriculture, reconnoitered the Cascade Range Forest Reserve to report on forest growth and sheep grazing there in an 1898 report. Subsequent forest survey in the late 1890s and early 1900s was stimulated by anticipation of the timber boom that would follow arrival of a railroad. In 1908, Gifford Pinchot's new Forest Service sent young Thornton Taft Munger to study the encroachment of lodgepole pine (Pinus...AuthorsLes JoslinSourceGen. Tech. Rep. PNW-GTR-711.

- Study objectives were to evaluate yearly fluctuations in herbage canopy cover and production to aid in defining characteristics of range condition guides. Sites are located in the forested Blue Mountains of central Oregon. They were selected from those used to develop range condition guides where soil, topographic, and vegetation parameters were measured as a characterization of best range condition. Plant community dominants were ponderosa pine/pinegrass, ponderosa pine/bitterbrush/Idaho fescue savanna, low sagebrush/bluebunch wheatgrass, and rigid sagebrush scabland. None of the sites...AuthorsFrederick C. HallKeywordsSourceGen. Tech. Rep. PNW-GTR-704 Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 44 pYear2007
- The Forest Inventory and Analysis Program collected, analyzed, and summarized field data on 54 forested plots on the islands in the Republic of Palau. Estimates of forest area, tree stem volume and biomass, the numbers of trees, tree damages, and the distribution of tree sizes were summarized for this statistical sample. Detailed tables and graphical highlights provide a summary of Palau’s forest resources and a comparison to 1987 data.AuthorsJoseph Donnegan, Sarah Butler, Olaf Kuegler, Brent Stroud, Bruce Hiserote, Kashgar RengulbaiKeywordsSourceRes.

- An econometric model of private land-use decisions is used to project land use to 2030 for each county in the continental United States. On a national scale, forest area is projected to increase overall between 0.1 and 0.2 percent per year between now and 2030. However, forest area is projected to decrease in a majority of regions, including the key forestry regions of the South and the Pacific Northwest westside. Urban area is projected to increase by 68 million acres, and cropland, pasture, rangeland, and Conservation Reserve Program land is projected to decline in area. Regional...AuthorsAndrew J.

- On October 18, 2006, a workshop was held in Vancouver, WA, with the title "Managing for wildlife habitat in Westside production forests." The purpose of the workshop was to provide prescriptions and guidelines for people who manage Westside forests (those west of the Cascade Mountains' crest) primarily for wood production, but because of mandate or personal preference, want to integrate wildlife values. The audience included over 150 professionals from forest industry, consulting firms, and public and tribal forest and wildlife management agencies. This proceedings includes ten papers...AuthorsTimothy B. Harrington, Gretchen E. NicholasKeywordsSourceGen. Tech. Rep. PNW-GTR-695.

- Given increasing need and decreasing capacity, the Forest Service outdoor recreation research program must strategize how best to address current and future priorities. The papers compiled here were presented at the National Workshop on Recreation Research and Management held in Portland, Oregon, February 8-10, 2005. Papers are organized around four themes: Understanding Forest Recreation Visitors, Recreation Planning & Monitoring, Recreation Management, and Special Issues in Recreation.AuthorsLinda E.

- A better understanding of consumer reaction and preferences for red alder (Alnus rubra Bong.) secondary products will help Alaska producers in entering new markets. In this study, red alder kitchen cabinets were commercially stained to six different levels and displayed at home shows in Portland, Oregon, and Anchorage, Alaska. The stains simulated the appearance of six commercial species. Respondents indicated their preferred cabinet doors, under the assumption of remodeling their kitchen. Brighter shades of stain were generally more popular than the three darkest shades. There were no...AuthorsDavid L. Nicholls, Joseph RoosSourceRes. Note PNW-RN-556.

- Current resource statistics for the Umatilla National Forest, based on two separate inventories conducted in 1993–96 and in 1997–2002, are presented in this report. Currently on the Umatilla National Forest, 89 percent of the land area is classified as forest land. The predominant forest type is grand fir (26 percent of forested acres) followed by the interior Douglas-fir (25 percent) and ponderosa pine (17 percent) types. The majority of net cubic foot wood volume (55 percent) comes from trees ranging in size from 11 to 23 inches diameter at breast height. The most commonly recorded cause...AuthorsGlenn Christensen, Paul Dunham, David C. Powell, Bruce HiseroteSourceRes. Bull. PNW-RB-253.

- This report examines socioeconomic changes that took place between 1990 and 2003 on and around lands managed by the Mount Hood National Forest in Oregon to assess the effects of the Northwest Forest Plan (the Plan) on rural economies and communities there. Three case communities were studied: the Greater Estacada Area, the Upper Hood River Valley, and the Villages of Mount Hood from Brightwood to Rhododendron. The report characterizes the region and its history, discusses management changes on the forest under the Plan and how they were perceived, describes socioeconomic change in the...AuthorsWilliam M.
