The U.S. Forest Service in the Pacific Northwest
Author: Gerald W. Williams
Publisher:
ISBN:
Category : History
Languages : en
Pages : 438
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.

Diversity, Ecology, and Conservation of Truffle Fungi in Forests of the Pacific Northwest
Author:
Publisher:
ISBN:
Category : Mycorrhizas
Languages : en
Pages : 204
Book Description
Forests of the Pacific Northwest have been an epicenter for the evolution of truffle fungi with over 350 truffle species and 55 genera currently identified. Truffle fungi develop their reproductive fruit-bodies typically belowground, so they are harder to find and study than mushrooms that fruit aboveground. Nevertheless, over the last five decades, the Corvallis Forest Mycology program of the Pacific Northwest Research Station has amassed unprecedented knowledge on the diversity and ecology of truffles in the region. Truffle fungi form mycorrhizal symbioses that benefit the growth and survival of many tree and understory plants. Truffle fruit-bodies serve as a major food souce for many forest-dwelling mammals. A few truffle species are commercially harvested for gourmet consumption in regional restaurants. This publication explores the biology and ecology of truffle fungi in the Pacific Northwest, their importance in forest ecosystems, and effects of various silvicultural practices on sustaining truffle populations. General management principles and considerations to sustain this valuable fungal resource are provided.

Updated Outdoor Recreation Use Values on National Forests and Other Public Lands
Author: John B. Loomis
Publisher:
ISBN:
Category : Forest reserves
Languages : en
Pages : 36
Book Description
This report summarizes more than 30 years of the literature on net economic value of outdoor recreation on public lands. The report provides average net willingness to pay or consumer surplus per day for 30 recreation activities at the national level. Values per day by recreation activity are also presented by census region of the United States. Detailed tables provide the average value per day as well as the standard error for calculating confidence intervals. Guidance for using these values in performing benefit transfer to unstudied sites is also provided. The report provides a link to a Web site where the spreadsheet that underlies the averages calculated in this report is available.
