Download or read book Diversity Ecology and Conservation of Truffle Fungi in Forests of the Pacific Northwest written by and published by . This book was released on 2009 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Effects of Forest Practices on Peak Flows and Consequent Channel Response written by Gordon E. Grant and published by DIANE Publishing. This book was released on 2010-09 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Includes a database of relevant studies reporting peak flow data across rain-, transient-, and snow-dominated hydrologic zones. Provides a quantitative comparison of changes in peak flow across both a range of flows and forest practices. Increases in peak flows generally diminish with decreasing intensity of percentage of watershed harvested and lengthening recurrence intervals of flow. Peak flow effects on channel morphology should be confined to stream reaches where channel gradients are less than 0.02 and streambeds are composed of gravel and finer material. Managers should evaluate the potential risk of peak flow increases based on factors such as presence of roads, specific mgmt. treatments employed, and watershed drainage efficiency.

Download or read book Forest Land Conversion Ecosystem Services and Economic Issues for Policy written by Robert A. Smail and published by DIANE Publishing. This book was released on 2010-10 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continued conversion and development of forest land pose a serious threat to the ecosystem services derived from forested landscapes. There are unavoidable challenges involved in quantifying the threats from forest conversion and their related costs to human well-being: (1) most attempts to quantify the costs of forest conversion on ecosystem services will necessarily rely on specific ecological science that is often emerging, changing, or simply nonexistent; (2) given the interconnected nature of ecosystem products and processes, any attempt to quantify the effects of forest conversion must grapple with jointness in production; (3) the ecology and the human dimensions of ecosystems are highly specific to spatial-temporal circumstances.
