This book was released on 1985 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, the fire management program of the Forest Service, U.S. Department of Agriculture, has come under closer scrutiny because of ever-rising program costs. The Forest Service has responded by conducting several studies analyzing the economic efficiency of its fire management program. Some components of the analytical models have been difficult to develop, particularly changes in the net value and output of timber caused by wildfire.

Book Synopsis Estimating Postfire Changes in Production and Value of Northern Rocky Mountain-Intermountain Rangelands by : David Lawrence Peterson
Download or read book Estimating Postfire Changes in Production and Value of Northern Rocky Mountain-Intermountain Rangelands written by David Lawrence Peterson and published by . This book was released on 1984 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simulation model was developed to estimate postfire changes in the production and value of grazing lands in the Northern Rocky Mountain-Intermountain region. Ecological information and management decisions were used to simulate expected changes in production and value after wildfire in six major rangeland types: permanent forested range (ponderosa pine), transitory range (Douglas-fir, larch, lodgepole pine, western white pine), mountain grassland, sagebrush, pinyon-juniper, and western hardwoods. Changes varied widely in quantity and duration among the range types. The largest decrease in net value was calculated for mountain grassland ($7/acre for a 2-year period). The largest increase in net value was calculated for a ponderosa pine sawtimber stand with 100 percent basal area removal ($36/acre for a l50~year period). The estimates calculated in this study should be useful in land and fire management planning in the Northern Rocky Mountain-Intermountain area.

Available in PDF, EPUB and Kindle. Book excerpt: Changes in recreation values after wildfire in the northern Rocky Mountains were determined by estimating the difference in the present net value of recreation activity with and without fire. To estimate the value of recreation activity at burned and unburned sites, a contingent market valuation approach was used. Hypothetical market transactions were created by soliciting bids from recreationists, which they based on phorographs of recreation sites depicting scenes before and after two kinds of fire--one of low intensity and the other of high intensity. They were asked what they would pay for the situation they most preferred. The results suggest that net value changes in recreation resources are generally low, and possibly insignificant in economic efficiency analyses of fire management programs.

Book Synopsis Effects of Timber Harvest Following Wildfire in Western North America by : David L. Peterson
Download or read book Effects of Timber Harvest Following Wildfire in Western North America written by David L. Peterson and published by DIANE Publishing. This book was released on 2010-11 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Timber harvest following wildfire leads to different outcomes depending on the biophysical setting of the forest, pattern of burn severity, operational aspects of tree removal, and other activities. Postfire logging adds to these effects by removing standing dead trees (snags) and disturbing the soil. The influence of postfire logging depends on the intensity of the fire, intensity of the logging operation, and mgmt. activities such as fuel treatments. Removal of snags reduces long-term fuel loads but generally results in increased amounts of fine fuels for the first few years after logging. Cavity-nesting birds, small mammals, and amphibians may be affected by harvest of standing dead and live trees, with negative effects on most species. Illustrations.
Book Synopsis Seed Dissemination in Small Clearcuttings in North-central California by : Philip M. McDonald
Download or read book Seed Dissemination in Small Clearcuttings in North-central California written by Philip M. McDonald and published by . This book was released on 1980 with total page 796 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a 1964-1967 study on the Challenge Experimental Forest, seedfall was evaluated in 2-, 5-, and 10-acre circular clearcuttings. During the 4 years, 10 seed crops, ranging from light to bumper, were produced by ponderosa pine. white fir, Douglas-fir, and incense cedar. Seedfall ranged from 76 to 40,691 sound seed per acre (188 to 100,547/ha) for a single species in a given year. From 89 to 100 percent of each species' seed fell within an area 1 1/2 times the height of the average dominant tree. Overall, seed distribution was highly variable.

Download or read book Effects of Timber Harvest Following Wildfire in Western North America written by and published by . This book was released on 2009 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. --
