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.

Download or read book Ecology of Wildfire Residuals in Boreal Forests written by Ajith Perera and published by John Wiley & Sons. This book was released on 2014-07-21 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will draw attention to the residuals in pan-borealforest fires and synthesize the state of knowledge. It willdo so by: (a) Examining the concept of fire residuals fromdifferent perspectives, (b) Reviewing the growing body ofscientific literature on the topic, (c) Conceptualizing theprocess of residual formation in relation to scale of firedisturbance, (d) Discussing the roles of fire residuals inecological processes, (e) Describing approaches and methods ofstudying fire residuals, (f) Compiling and summarizing what isknown about fire residual vegetation with respect to their extent,spatial patterns, and temporal changes, (g) Discussing howthe knowledge of fire residuals is applied in forest management,including social perspective, and (h) Synthesizing the state ofknowledge, identifying its uncertainties and gaps, and proposingresearch hypotheses. The authors use pan-borealscientific literature on boreal fire residuals as well as firebehaviour, fire ecology, habitat ecology, and geochemicalprocesses. For readers this book will be a reference forknowledge to date and a meta-analysis of research trends during thepast few decades. In addition, the authors judiciouslyinclude views constructed from their observations and researchexperience, from boreal Canada, when they synthesize andconceptualize the knowledge. They also incorporateinformation extracted from their discussions and interactions withNorth American and European ecologists, forest managers, andconservationists to provide insight to different views andperspectives on the fire residuals of the boreal forest system. This book will inform researchers and students who studyboreal forest ecology, as well as policymakers and forest managerswho apply forest ecological knowledge in forest management. This book provides a review and coalescence of the currentknowledge of boreal forest fire residuals, which at present issporadic and has not been unified or synthesized. Moreover,these are presently viewed myopically and parochially, rather thanholistically. The intent of the synthesis is to identifyknowledge uncertainties and gaps and propose topics for futureresearch. Most importantly, it brings together fire behaviour,ecological scale, vegetation ecology, and conservation biology toconceptualize forest fire residuals. Although focused onboreal forests, the contents and principles presented are also bepertinent to other large-scale fire driven forest systems, such asdry montane forests in North America and Australian eucalyptforests. This book will add to the current knowledge base byproviding a source of significant literature to-date, an in-depthexamination of baseline concepts of forest fire residuals, as wellas questions and research ideas to address the identified gaps. Thetiming is ideal because the knowledge base is beginning to expandand the interest in the topic is increasing: such a synthesis wouldprovide an important foundation for future advances in this veryrelevant topical area. The book is a compact, yet comprehensive,dissertation of remnant vegetation in boreal forest fires withrespect to their formation, role in ecological processes, appliedimportance, and a synthesis of state-of-the-knowledge and futureresearch directions. The scope is boreal forests worldwide,including North America, Europe, and Asia. Brief TOC: Why theinterest in boreal fire residuals; what are fire residuals; how arefire residuals formed; what are the ecological roles of the fireresiduals; what is the role of residuals in forest managementapplications; synthesis, knowledge, uncertainties and researchneeds.

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.

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 2008-01-11 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is a natural forest disturbance? How well do we understand natural forest disturbances and how might we emulate them in forest management? What role does emulation play in forest management? Representing a range of geographic perspectives from across Canada and the United States, this book looks at the escalating public debate on the viability of natural disturbance emulation for sustaining forest landscapes from the perspective of policymakers, forestry professionals, academics, and conservationists. This book provides a scientific foundation for justifying the use of and a solid framework for examining the ambiguities inherent in emulating natural forest landscape disturbance. It acknowledges the divergent expectations that practitioners face and offers a balanced view of the promises and challenges associated with applying this emerging forest management paradigm. The first section examines foundational concepts, addressing questions of what emulation involves and what ecological reasoning substantiates it. These include a broad overview, a detailed review of emerging forest management paradigms and their global context, and an examination of the ecological premise for emulating natural disturbance. This section also explores the current understanding of natural disturbance regimes, including the two most prevalent in North America: fire and insects. The second section uses case studies from a wide geographical range to address the characterization of natural disturbances and the development of applied templates for their emulation through forest management. The emphasis on fire regimes in this section reflects the greater focus that has traditionally been placed on understanding and managing fire, compared with other forms of disturbance, and utilizes several viewpoints to address the lessons learned from historical disturbance patterns. Reflecting on current thinking in the field, immediate challenges, and potential directions, the final section moves deeper into the issues of practical applications by exploring the expectations for and feasibility of emulating natural disturbance through forest management.

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.

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
