This book was released on 2008 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analyzes a range of fuel treatments for representative dry forest stands in the Western U.S. dominated by ponderosa pine, Douglas-fir, & pinyon pine. Six silvicultural options (no thinning; thinning from below to 50 trees per acre [tpa], 100 tpa, 200 tpa, & 300 tpa; & prescribed fire) are considered in combination with the surface fuel treatments (no treatment, pile & burn, & prescribed fire), resulting in a range of alternative treatments for each representative stand. Fuel treatment scenarios presented here can be used by resource managers to examine alternatives for Nat. Environ. Policy Act documents & other applications that require scientifically based info. to quantify the effects of modifying forest structure & surface fuels. Illustrations.

Book excerpt: Guide to Fuel Treatments analyzes a range of fuel treatments for representative dry forest stands in the Western United States with overstories dominated by ponderosa pine (Pinus ponderosa), Douglas-fir (Pseudotsuga menziesii), and pinyon pine (Pinus edulis). Six silvicultural options (no thinning; thinning from below to 50 trees per acre [tpa], 100 tpa, 200 tpa, and 300 tpa; and prescribed fire) are considered in combination with three surface fuel treatments (no treatment, pile and burn, and prescribed fire), resulting in a range of alternative treatments for each representative stand. The Fire and Fuels Extension of the Forest Vegetation Simulator (FFE-FVS) was used to calculate the immediate effects of treatments on surface fuels, fire hazard, potential fire behavior, and forest structure. The FFEFVS was also used to calculate a 50-year time series of treatment effects at 10-year increments. Usually, thinning to 50 to 100 tpa and an associated surface fuel treatment were shown to be necessary to alter potential fire behavior from crown fire to surface fire under severe fire weather conditions. This level of fuel treatment generally was predicted to maintain potential fire behavior as surface fire for 30 to 40 years, depending on how fast regeneration occurs in the understory, after which additional fuel treatment would be necessary to maintain surface fire behavior. Fuel treatment scenarios presented here can be used by resource managers to examine alternatives for National Environmental Policy Act documents and other applications that require scientifically based information to quantify the effects of modifying forest structure and surface fuels.

Available in PDF, EPUB and Kindle. Book excerpt: The Guide to Fuel Treatments analyzes a range of potential silvicultural thinnings and surface fuel treatments for 25 representative dry-forest stands in the Western United States. These stands are the focus of potential management activities intended to modify forest structure and fuel to reduce crown-fire hazard on public lands. The guide provides quantitative guidelines and visualizations for treatments based on scientific principles identified for reducing potential crown fires.

Download or read book Assessment of Timber Availability from Forest Restoration Within the Blue Mountains of Oregon written by and published by . This book was released on 2008 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changes in forest management have detrimentally affected the economic health of small communities in the Blue Mountain region of Oregon over the past few decades. A build-up of small trees threatens the ecological health of these forests and increases wildland fire hazard. Hoping to boost their economies and also restore these forests, local leaders are interested in the economic value of timber that might be available from thinning treatments on these lands. This study identified densely stocked stands where thinning could provide a reliable source of wood, and examined the quantity, distribution, and economic value of the resulting timber for 5.5 million acres of national forest lands in eastern Oregon. Our findings verified local land managers' observations that the land base to support timber harvest targets in the region is smaller than anticipated in the past. Legal restrictions and current management practices have reduced the acreage available for harvest and mechanical restoration. Additionally, we found that on lands where active forestry is allowable, thinning of most densely stocked stands would not be economically viable. Findings from this analysis can help establish a common understanding of Blue Mountains vegetative and economic conditions for managers trying to restore the region's national forests.
Download or read book The Landscape Ecology of Fire written by Donald McKenzie and published by Springer Science & Business Media. This book was released on 2011-01-04 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global warming is expected to change fire regimes, likely increasing the severity and extent of wildfires in many ecosystems around the world. What will be the landscape-scale effects of these altered fire regimes? Within what theoretical contexts can we accurately assess these effects? We explore the possible effects of altered fire regimes on landscape patch dynamics, dominant species (tree, shrub, or herbaceous) and succession, sensitive and invasive plant and animal species and communities, and ecosystem function. Ultimately, we must consider the human dimension: what are the policy and management implications of increased fire disturbance, and what are the implications for human communities?
Download or read book Ecological Silviculture written by Brian J. Palik and published by Waveland Press. This book was released on 2020-05-15 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical silviculture has often emphasized timber models, fundamentally based in production agriculture. This books presents silvicultural methods based in natural forest models—models that emulate natural disturbances and development processes, sustain biological legacies, and allow time to take its course in shaping stands. These methods, dubbed “ecological forestry,” have been successfully implemented by foresters for decades managing a wide variety of forestlands. Ecological silvicultural strategies protect threatened and rare species, sustain biological diversity, and provide habitat for game and non-game species, all while providing timber in profitable ways.

This book was released on 2011-05 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides an ecological foundation for mgmt. of the diverse ecosystems and fire regimes of N. America, based on scientific principles of fire interactions with vegetation, fuels, and biophysical processes. Detailed discussion of six ecosystems ¿ ponderosa pine forest (western N. America), chaparral (Calif.), boreal forest (Alaska and Canada), Great Basin sagebrush (inter-mountain West), pine and pine-hardwood forests (Southern Appalachian Mountains), and longleaf pine (Southeastern U.S.) ¿ illustrates the complexity of fire regimes and that fire mgmt. requires a clear regional focus that recognizes where conflicts might exist between fire hazard reduction and resource needs.
