Birds and Burns of the Interior West by Anonim Pdf

This publication provides information about prescribed fire effects on habitats and populations of birds of the interior West and a synthesis of existing information on bird responses to fire across North America. Our literature synthesis indicated that aerial, ground, and bark insectivores favored recently burned habitats, whereas foliage gleaners preferred unburned habitats.

Old Growth in a New World by Thomas A. Spies,Sally L. Duncan Pdf

Old-growth forests represent a lofty ideal as much as an ecosystem—an icon of unspoiled nature, ecological stability, and pristine habitat. These iconic notions have actively altered the way society relates to old-growth forests, catalyzing major changes in policy and management. But how appropriate are those changes and how well do they really serve in reaching conservation goals? Old Growth in a New World untangles the complexities of the old growth concept and the parallel complexity of old-growth policy and management. It brings together more than two dozen contributors—ecologists, economists, sociologists, managers, historians, silviculturists, environmentalists, timber producers, and philosophers—to offer a broad suite of perspectives on changes that have occurred in the valuing and management of old-growth forests in the Pacific Northwest over the past thirty years. The book • introduces the issues and history of old-growth values and conservation in the Pacific Northwest; • explores old growth through the ideas of leading ecologists and social scientists; • addresses the implications for the future management of old-growth forests and considers how evolving science and social knowledge might be used to increase conservation effectiveness. By confronting the complexity of the old-growth concept and associated policy and management challenges, Old Growth in a New World encourages productive discussion on the future of old growth in the Pacific Northwest and offers options for more effective approaches to conserving forest biodiversity.

Diversity, Ecology, and Conservation of Truffle Fungi in Forests of the Pacific Northwest by Anonim Pdf

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.

Ecological Foundations for Fire Management in North American Forest and Shrubland Ecosystems by Anonim Pdf

This synthesis provides an ecological foundation for management of the diverse ecosystems and fire regimes of North America, based on scientific principles of fire interactions with vegetation, fuels, and biophysical processes. Although a large amount of scientific data on fire exists, most of those data have been collected at small spatial and temporal scales. Thus, it is challenging to develop consistent science-based plans for large spatial and temporal scales where most fire management and planning occur. Understanding the regional geographic context of fire regimes is critical for developing appropriate and sustainable management strategies and policy. The degree to which human intervention has modified fire frequency, intensity, and severity varies greatly among different ecosystems, and must be considered when planning to alter fuel loads or implement restorative treatments. Detailed discussion of six ecosystems--ponderosa pine forest (western North America), chaparral (California), boreal forest (Alaska and Canada), Great Basin sagebrush (intermountain West), pine and pine-hardwood forests (Southern Appalachian Mountains), and longleaf pine (Southeastern United States)-- illustrates the complexity of fire regimes and that fire management requires a clear regional focus that recognizes where conflicts might exist between fire hazard reduction and resource needs. In some systems, such as ponderosa pine, treatments are usually compatible with both fuel reduction and resource needs, whereas in others, such as chaparral, the potential exists for conflicts that need to be closely evaluated. Managing fire regimes in a changing climate and social environment requires a strong scientific basis for developing fire management and policy.
