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.

Forest landscape disturbances are a global phenomenon. Simulation models are an important tool in understanding these broad scale processes and exploring their effects on forest ecosystems. This book contains a collection of insights from a group of ecologists who address a variety of processes: physical disturbances such as drought, wind, and fire; biological disturbances such as defoliating insects and bark beetles; anthropogenic influences; interactions among disturbances; effects of climate change on disturbances; and the recovery of forest landscapes from disturbances—all from a simulation modeling perspective. These discussions and examples offer a broad synopsis of the state of this rapidly evolving subject.

This publication is a compendium of summaries of presentations from a symposium that discussed the concepts, challenges, and potential consequences of implementing emulation of natural forest landscape disturbances at the landscape level in forest management. The first set of presentations covers such topics as predicting natural forest disturbances, predicting fire regimes and forest insect disturbance regimes, silvicultural concepts, the ecological basis for emulation, boreal forest management, and the economics of emulation forestry. The second set presents case studies from across northern & central North America to illustrate some practical applications of the concepts behind emulation of natural forest landscape disturbances.

Large and intense wildfires are integral to the globally important boreal forest biome. While much is known about boreal wildfires, the focus on forest remnants that either escape or survive these intense fires is a recent phenomenon: academics now study ecological processes of wildfire residuals, forest policymakers use their patterns to design harvest strategies, forest managers consider their economic value, and conservationists recognize their intrinsic ecological importance. Ecology of Wildfire Residuals in Boreal Forests is the first book to explore ecological patterns and processes of what does not burn within boreal wildfires. Following a brief introduction to the boreal forest biome, it discusses the processes that form wildfire residuals; how they are studied, with various approaches and methods; the types, extent, and ecological functions of wildfire residuals; and their role in forest management applications, all in the context of ecological scale. This book is a reference for researchers and graduate students studying boreal forest ecology, as well as for policymakers and forest managers. It adopts a non-reductionist perspective that will be of interest to scientists from conservation science, forest ecology, forest management, and timber production. Brings together fire behaviour, ecological scale, vegetation ecology, and conservation biology to provide a cross disciplinary, multi-scale, and an integrative discussion of forest fire residuals Captures the state of knowledge with a meta-analysis of research trends during the past few decades, with a comprehensive review of the literature, a compilation of key references, and a list of key topics relevant to the study of boreal wildfire residuals Identifies the major gaps and uncertainties in the present body of knowledge, including a critique of study techniques and reporting practices to date, and proposes a set of terms and definitions and a list of research questions and priorities Includes the authors’ observations and research experience from boreal Canada, and information extracted from interactions with North American and European ecologists, forest managers, and conservationists

Climate change, urban sprawl, abandonment of agriculture, intensification of forestry and agriculture, changes in energy generation and use, expansion of infrastructure networks, habitat destruction and degradation, and other drivers of change occur at increasing rates. They affect patterns and processes in forest landscapes, and modify ecosystem services derived from those ecosystems. Consequently, rapidly changing landscapes present many new challenges to scientists and managers. While it is not uncommon to encounter the terms “global change” and “landscape” together in the ecological literature, a global analyses of drivers of change in forest landscapes, and their ecological consequences have not been addressed adequately. That is the goal of this volume: an exploration of the state of knowledge of global changes in forested landscapes with emphasis on causes and effects, and challenges faced by researchers and land managers. Initial chapters identify and describe major agents of landscape change: climate, fire, and human activities. The next series of chapters address implications of changes on ecosystem services, biodiversity conservation and carbon flux. A chapter that describes methodologies of detecting and monitoring landscape changes is presented followed by chapter that highlights the many challenges forest landscape managers face amidst of global change. Finally, we present a summary and a synthesis of the main points presented in the book. Each chapter will contain the individual research experiences of chapter authors, augmented by review and synthesis of global scientific literature on relevant topics, as well as critical input from multiple peer reviewers.

Classical silviculture has often emphasized timber models, fundamentally based in production agriculture. This books presents silvicultural methods based in natural forest models—models that emulate natural disturbances and development processes, sustain biological legacies, and allow time to take its course in shaping stands. These methods, dubbed “ecological forestry,” have been successfully implemented by foresters for decades managing a wide variety of forestlands. Ecological silvicultural strategies protect threatened and rare species, sustain biological diversity, and provide habitat for game and non-game species, all while providing timber in profitable ways.

Over the last two decades, the topic of forest ecosystem services has attracted the attention of researchers, land managers, and policy makers around the globe. The services rendered by forest ecosystems range from intrinsic to anthropocentric benefits that are typically grouped as provisioning, regulating, supporting, and cultural. The research efforts, assessments, and attempts to manage forest ecosystems for their sustained services are now widely published in scientific literature. This volume focuses on broad-scale aspects of forest ecosystem services, beyond individual stands to large landscapes. In doing so, it illustrates the conceptual and practical opportunities as well as challenges involved with planning for forest ecosystem services across landscapes, regions, and nations. The goal here is to broaden the scope of land use planning through the adoption of a landscape-scale approach. Even though this approach is complex and involves multiple ecological, social, cultural, economic, and political dimensions, the landscape perspective appears to offer the best opportunity for a sustained provision of forest ecosystem services.

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.
