This book was released on 2007 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The effects of clearcutting and slashburning on vegetation and soil composition and structure were monitored at permanent plots in the Prince George Forest District for up to 10 years post-burn. Changes in floristic composition, percent cover, and height were documented and described for each study area. At each site, standard fire weather stations were used to determine fire weather codes and indices and predict forest floor moisture content. Woody fuel loading and consumption and burn severity were determined using a line-intercept approach in standard fire effects assessment triangles and circular plots. Forest floor consumption, mineral soil exposure, and woody fuel consumption were compared to values predicted by the Prescribed Fire Predictor."--Document.

Available in PDF, EPUB and Kindle. Book excerpt: Slashburning has been widely used in British Columbia and some work has been done to improve the tools used to predict fire effects in cutblocks. This report provides information that can be used to guide the application of the most commonly used tools--the Canadian Forest Fire Weather Index System (CFFWIS) and Prescribed Fire Predictor (PFP)--in SBS cutblocks. The objectives of this study were: to quantify and describe changes in percent cover, height, species composition, and diversity of vegetation on forest floor and mineral soil substrates, for 10 years after burning in an SBSvk subzone site; to determine the relationship between actual fire effects (i.e., duff and woody fuel consumption and mineral soil exposure) and those predicted by the PFP; and to determine the relationship between predicted and actual duff moisture level when various conversion equations are used with the CFFWIS to predict duff moisture level.

This book was released on 2005 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Normalized Burn Ratio and Composite Burn Index were used to classify burn severity in three sites that experienced lightning-ignited wildfire in the year 2000. The effect of burn severity (unburned, low, moderate, and high severity classes) was investigated on vegetation and soil microbial community composition. Vegetation communities showed a strong response to burn severity, with distinct communities associated with each burn severity class. Indicator Species Analysis was used to identify plant species associated with each burn severity class; one interesting result from ISA was that trembling aspen (Populus tremuloides) seedlings emerged as an indicator of the moderate severity class. Species richness and tree seedling density differed among burn severity classes. Soil microbial communities were analyzed using Phospholipid Fatty Acid analysis and showed moderate variation among burn severity classes and study sites. Total soil carbon and nitrogen did not differ with burn severity. The C:N ratio, total soil S, and soil pH differed significantly among burn severity classes. While the effect of burn severity is pronounced upon vegetation three years post-fire, effects on soil microbial communities are less evident. This could be attributed to the insulating properties of soils, the time elapsed after fire, or it could be an artifact of the sampling technique.
Download or read book Succession After Slashburning in an Engelmann Spruce subalpine Fir Subzone Variant written by Evelyn Hope Hamilton and published by . This book was released on 2006 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was undertaken to determine the successional development after a slashburn of known severity on an Engelmann Spruce-Subalpine Fir (ESSF) biogeoclimatic zone site. Herbaceous and shrubby vegetation composition, cover, and height were monitored along with the growth of planted spruce seedlings for 11 years in 30 permanent sample plots. Fire effects were determined using depth-of-burn pins to measure forest floor consumption and fuel assessment triangles to measure fuel loading and consumption following a microplot approach. Fire weather conditions were determined using standard methods outlined in the Canadian Forest Fire Weather Index System. The objectives of this study were to quantify and describe changes in percent cover, height, species composition, and diversity of vegetation following prescribed burning; to quantify and describe the growth and mortality of planted hybrid white spruce (Picea engelmannii x glauca) seedlings after prescribed burning; and to quantify site conditions, including fire weather and forest floor moisture content, and fire effects, such as forest floor and slash consumption, at the time of burning.

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 2011 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a print on demand edition of a hard to find publication. This report synthesizes the literature and current state of knowledge pertaining to re-introducing fire in stands where it has been excluded for long periods and the impact of these introductory fires on overstory tree injury and mortality. Only forested ecosystems in the United States that are adapted to survive frequent fire are included. Treatment options that minimize large-diameter and old tree injury and mortality in areas with deep duff and methods to manage and reduce duff accumulations are discussed. Pertinent background information on tree physiology, properties of duff, and historical versus current disturbance regimes are also discussed. Charts and tables.
Download or read book Quantifying the Effects of Post fire Decision making on Forest Recovery in a Severly Burned Southwestern Landscape written by Matthew D. Hurteau and published by . This book was released on 2020 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire-exclusion and changing climatic conditions are increasing the area burned and the size of high-severity burn patches in historically frequent-fire forests. In the southwestern US, distance to seed source and hot, dry conditions in high-severity patches is limiting tree regeneration. While post-fire tree planting can overcome dispersal limitations, high planted seedling mortality rates are common in the southwest. Microclimatic conditions are influential on tree seedling survival and can vary as a function of topography and vegetation cover type. We sought to determine how planted seedling survival and growth would vary as a function of aspect and vegetation cover type in the footprint of the 2011 Las Conchas Fire in northern New Mexico. We also sought to determine how the probability of fire would influence landscape successional development. To quantify the effects of aspect and cover type on seedling survival and growth, we planted ponderosa pine and Douglas-fir seedlings by aspect (north vs south) and cover type (open, under shrub) in a full factorial design. To quantify the effects of fire probability on landscape successional development, we used a simulation model to test the sensitivity of the system to increasing fire probability. We found that topographic wetness index and topographic roughness index were good predictors of both survival and growth. We also found that increasing fire probability can prevent the establishment of tree seedlings following high-severity wildfire, causing the transition from forest to non-forest to be reinforced.
