Book Description
The Northwest has been at the forefront of forest management and research in the United States for more than one hundred years. In The U.S. Forest Service in the Pacific Northwest, Gerald Williams provides an historical overview of the part the Forest Service has played in managing the Northwest's forests. Emphasizing changes in management policy over the years, Williams discusses the establishment of the national forests in Oregon and Washington, grazing on public land, the Great Depression, World War II, and the rise of multiple-use management policies. He draws on extensive documentation of the post-war development boom to explore its effects on forests and Forest Service workers. Discussing such controversial issues as roadless areas and wilderness designation; timber harvesting; forest planning; ecosystems; and spotted owls, Williams demonstrates the impact of 1970s environmental laws on national forest management. The book is rich in photographs, many drawn from the Gerald W. Williams Collection, housed in University Archives at Oregon State University Libraries. Extensive appendices provide detailed data about Pacific Northwest forests. Chronicling a century of the agency's management of almost 25 million acres of national forests and grasslands for the people of the United States, The U.S. Forest Service in the Pacific Northwest is a welcome and overdue resource.

Book Description
This publication presents highlights of a recent southeast Alaska inventory and analysis conducted by the Pacific Northwest Research Station Forest Inventory and Analysis Program (USDA Forest Service). Southeast Alaska has about 22.9 million acres, of which two-thirds are vegetated. Almost 11 million acres are forest land and about 4 million acres have nonforest vegetation (herbs and shrubs). Species diversity is greatest in western hemlockAlaska cedar closed-canopy forests, in mixed-conifer open and woodland forests, and in open tall alder-willow shrub type. Of the forest land, 4.1 million acres are classified as timberland (unreserved productive forest land). About 4.4 million acres of forest land are reserved from harvest; the majority of this reserved land (85 percent) is on the Tongass National Forest (USDA Forest Service). The volume of timber on timberland was estimated at 21,040 million cubic feet; the majority of volume88 percentis on the Tongass National Forest. Seventy-four percent of timberland acres and 84 percent of the growing-stock volume is in sawtimber stands older than 150 years, with western hemlock or western hemlockSitka spruce mix predominating. Most timberland in southeast Alaska is of relatively low productivity, producing less than 85 cubic feet per acre per year. For most timberland acres, average annual growth exceeds average annual mortality and harvest.
