Book Synopsis Size Class Distribution and Spatial Proximity of Fires in a Simulated Boreal Forest Fire Regime in Relation to Ontario's Policy Directions for Emulating Natural Disturbance by : Ajith Perera
Download or read book Size Class Distribution and Spatial Proximity of Fires in a Simulated Boreal Forest Fire Regime in Relation to Ontario's Policy Directions for Emulating Natural Disturbance written by Ajith Perera and published by . This book was released on 2009 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the other three ecoregions, it underestimated fire size distribution under all simulation scenarios. The guide's direction for spatial proximity was not congruent with results from any simulated scenario in any ecoregion. However, the probability of spatial proximity was low in all but one ecoregion. In addition to the assessment of NDPE guide's direction, this study demonstrates that fire size distributions appear to be unique to ecoregions, and that these can vary further if the fire weather conditions change."--Abstract

Book Synopsis Using BFOLDS to Characterize Fire Regimes by : Wenbin Cui
Download or read book Using BFOLDS to Characterize Fire Regimes written by Wenbin Cui and published by . This book was released on 2009 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest fires are the result of complex interactions of weather and vegetation and are highly probabilistic. Characterizing forest fire regimes, the synoptic properties of spatio-temporal variability of individual fires, is important for many forest and fire management purposes. BFOLDS 1.0 (Boreal Forest Landscape Dynamics Simulator) simulates forest fires and forest succession for large areas over long periods. Resulting fire regime simulations are emergent properties of many stochastic and spatially explicit model processes as well as user assumptions and input data. Here the authors demonstrate the use of BFOLDS in characterizing a forest fire regime, using a large boreal ecoregion as an example and readily available forest cover and spatial weather data as primary input.--Document.

Perera and published by . This book was released on 2006 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This prospectus presents a broad framework for a series of research studies to investigate Ontario boreal forest fire regime at multiple scales. The broad research goal is to reduce uncertainties in knowledge about boreal forest fire regimes related to policy directions in Ministry of Natural Resources' Forest management guide for natural disturbance pattern emulation. The research studies are grouped into three categories: reviews and syntheses of published literature; determining the characteristics of the broad-scale fire regime in boreal Ontario; and spatial mapping and monitoring.
Book Synopsis An Assessment of Residual Patches in Boreal Fires in Relation to Ontario's Policy Directions for Emulating Natural Forest Disturbance by : Ajith Perera
Download or read book An Assessment of Residual Patches in Boreal Fires in Relation to Ontario's Policy Directions for Emulating Natural Forest Disturbance written by Ajith Perera and published by . This book was released on 2009 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Forest Management Guide for Natural Disturbance Pattern Emulation (NDPE), which has been applied in Ontario since 2003, specifies directions and provides standards and guidance to emulate fire disturbances. Included in the NDPE guide are specific directions about the amount of residual structure to be retained during forest harvest. Improved understanding of the characteristics of post-fire residual structure in natural conditions will help forest policymakers to provide better strategic guidance for emulating natural fire disturbance patterns during forest harvesting, and forest managers to make better tactical decisions about retaining post-harvest residual structure to emulate fire disturbances. The objective of this report is to characterize the extent and variability of post-fire residual patch occurrence in natural boreal forest fire events to better understand their extent and spatial patterns and to relate these results to the directions provided in Ontario's NDPE guide.--Document.
Book Synopsis An Assessment of Tree, Snag and Downed Wood Residuals in Boreal Fires in Relation to Ontario's Policy Directions for Emulating Natural Forest Disturbance by : Ajith Perera
Download or read book An Assessment of Tree, Snag and Downed Wood Residuals in Boreal Fires in Relation to Ontario's Policy Directions for Emulating Natural Forest Disturbance written by Ajith Perera and published by . This book was released on 2008 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to residual tree mortality, the complement of snag and downed wood residuals increased in time. After three years, abundance of large diameter residual trees was very low, and congruent with directions provided in the NDPE guide for retaining residual trees post-harvest. Local fire intensity appeared to be the most important global determinant of occurrence of residual trees, but with an inverse relationship. Our results do not support the hypotheses that pre-burn forest cover and site conditions are reliable global predictors of residual tree occurrence."--Abstract

This book was released on 2008 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study were to characterize the abundance and variability in residual stand structure within unsuppressed boreal forest fire events to understand the extent of post-fire residual structure (residual trees, residual snags, and downed wood), its within- and among-fire variability, as well as how it changes during the first few years following the fire. Specifically, the report examines unsuppressed fires in boreal Ontario in order to describe the extent and variability of the residual structure that results from forest fires, and to document the immediate post-fire changes that occur in residual structure.
Book Synopsis Mapping Wildfire Susceptibility with the BURN-P3 Simulation Model by : Marc-André Parisien
Download or read book Mapping Wildfire Susceptibility with the BURN-P3 Simulation Model written by Marc-André Parisien and published by . This book was released on 2005 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resource management in fire-dominated ecosystems requires an understanding of the probability of wildfire occurring & spreading at different points in a landscape. This report describes an approach to evaluating wildfire susceptibility, or burn probability, for fire-prone landscapes such as the boreal forest of North America. The approach involves use of the BURN-P3 (probability, prediction, & planning) landscape-level simulation model, which combines deterministic fire growth based on the Canadian Fire Behaviour Prediction System and spatial data for forest fuels & topography with probabilistic fire ignitions & spread events derived from historical fire & weather data. A case study of the application of BURN-P3 is undertaken for a boreal mixedwood area of central Saskatchewan. The results presented highlight the importance of landscape features to wildfire susceptibility and indicate whether assessments based solely on stand-level characteristics are adequate.
Book Synopsis Ecological Foundations for Fire Management in North American Forest and Shrubland Ecosystems by :
Download or read book Ecological Foundations for Fire Management in North American Forest and Shrubland Ecosystems written by and published by . This book was released on 2009 with total page 102 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.

Book Synopsis A Review of Published Knowledge on Post-fire Residuals Relevant to Ontario's Policy Directions for Emulating Natural Disturbance by : Ajith H. Perera
Download or read book A Review of Published Knowledge on Post-fire Residuals Relevant to Ontario's Policy Directions for Emulating Natural Disturbance written by Ajith H. Perera and published by . This book was released on 2007 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire intensity within forest fires varies as weather and site conditions change, leaving live forest patches, and individual trees, as well as dead structure as standing trees and downed stems. Such remnant structure from pre-burn forests are collectively known as post-fire residuals. This review of the literature is focused on establishing the state of knowledge on post-fire residuals as relevant to directions in Ontario's Forest management guide for natural disturbance pattern emulation (NDPE). It covers information reported for boreal North America, captured from reports that are published and universally accessible. The report includes a description of the methodological steps followed in searching, reviewing, and synthesizing literature; definitions and descriptions of post-fire residuals; abundance and variability of specific types of post-fire residual structure; and associations of post-fire residual structure with forest cover, site conditions, and fire behaviour. It also identifies knowledge gaps and uncertainties about aspects of post-fire residual structure that are relevant to the NDPE guide directions.--Includes text from document.
