Author: Diversity, Ecology, and Conservation of Truffle Fungi in Forests of the Pacific Northwest

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.

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.
