Book Description
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.

Book Description
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 Description
Ontario's "Forest management guide for natural disturbance pattern emulation" provides direction for emulating natural fire disturbances in forest management planning. This report examines the North American scientific literature on natural fire disturbances in relation to the directions in this guide for: landscape harvest size patterns; landscape harvest patch separation; residual stands; and residual trees & downed woody debris. Gaps in the published knowledge are identified. An annotated bibliography of the literature reviewed for the report is included.

Book Description
"This bibliography includes a list and descriptions of the content of publications written or co-authored by staff of the Ontario Ministry of Natural Resources' Ontario Forest Research Institute between 2006 and 2010. During this five-year period, over 150 publications were produced by the institute's 14 research scientists, including a book, 83 journal articles, 31 reports, 10 technical notes, 5 newsletters, and 11 papers/summaries in conference/ workshop proceedings. The overall focus of the publications is forest resource management-related research and practice. Topical areas and scales of investigation are diverse and include natural disturbance regimes and landscape dynamics; carbon budgets and effects of climate change on forests; and silviculture studies on site preparation, tree improvement, vegetation management, growth and yield, disease management, and harvesting in conifer, mixedwood, and hardwood forests. Author and subject indexes are provided."--Document.

Book Description
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 Description
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
