Book excerpt: This study summarizes the microclimatic effects of burning of open subarctic woodland in terms of soil temperature, soil moisture, radiation, evaporation and evapotranspiration. The study also compares the microclimatic characteristics of lichen woodland and of variously aged burns, to wet and dry open tundra areas, in terms of their energy balances.

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. --

This book was released on 2018 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildfire activity in North American boreal forest and tundra ecosystems is strongly controlled by climate, indicating the potential for widespread fire-regime shifts in response to ongoing and future climate change. This dissertation focuses on understanding how fire regimes in boreal forest and tundra ecosystems respond to variability in past, present, and future climate. Chapter 1 addresses how climate, vegetation, and topography control the spatial distribution of fire occurrence in Alaskan boreal forest and tundra ecosystems. Through statistical modeling, I found that climate was the primary control of historical fire activity. Informing these statistical models with 21st-century climate projections suggests tundra and forest-tundra ecosystems will be particularly vulnerable to fire-regime shifts, due to increasing summer temperatures. In some areas, fire may become four times more likely to occur by 2100, relative to the past 6,000-35,000 years. In Chapter 2, I studied the importance of vegetation as a control of fire activity across North American boreal forests, using continental-scale fire and vegetation datasets spanning the past several decades. After climate, fire activity was most strongly linked to landscape tree cover (%). The likelihood of burning was also not independent of past fire, suggesting negative fire-vegetation feedbacks exist across North American boreal forests. These feedbacks are estimated to have reduced total area burned by ≈ 2.7-3.6 x106 ha (4-5%) from 1981-2016, relative to expectations if there were no feedbacks. While these negative fire-vegetation feedbacks may offset climatically driven increases in fire activity for several decades, continued warming and increasing aridity will likely overwhelm the mediating effects of vegetation by the mid- to late-21st century. In Chapter 3, I evaluate the ability of the statistical models from Chapter 1 to project fire regimes outside of the observational period (i.e., 1950-2009 CE). I informed these models with GCM data from 850-1850 CE, and compared these paleo-projections to independent fire histories derived from lake-sediment records. The accuracy of the paleo-projections varied regionally, with uncertainty highest in regions close to an observed temperature threshold to burning. These results highlight how threshold relationships can cause significant uncertainty in anticipating the timing, location, and magnitude of future ecosystem change.

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.
