Forest Dynamics and Disturbance Regimes by Lee E. Frelich Pdf
Temperate-zone forests are being shaped continuously by wind, fire and grazing. This book considers these disturbances and consequent issues such as recovery from disturbance, the changing composition of tree species within the forest and the formation of mosaics of different forest types across the landscape.
Ecosystem Management in the Boreal Forest by Sylvie Gauthier Pdf
Forest Ecosystem Management. A management approach that aims to maintain healthy and resilient forest ecosystems by focusing on a reduction of differences between natural and managed landscapes to ensure long-term maintenance of ecosystem functions and thereby retain the social and economic benefits they provide to society.That is the definition of forest ecosystem management proposed in this book, which provides a summary of key ecological concepts supporting this approach. The book includes a review of major disturbance regimes that shape the natural dynamics of the boreal forest and gives examples from different Canadian boreal regions. Several projects implementing the forest ecosystem management approach are presented to illustrate the challenges created by current forestry practices and the solutions that this new approach can provide. In short, knowledge and understanding of forest dynamics can serve as a guide for forest management. Planning interventions based on natural dynamics can facilitate reconciliation between forest harvesting needs and the interests of other forest users.
The Ecology of Natural Disturbance and Patch Dynamics by Steward T.A. Pickett,P. S. White Pdf
Ecologists are aware of the importance of natural dynamics in ecosystems. Historically, the focus has been on the development in succession of equilibrium communities, which has generated an understanding of the composition and functioning of ecosystems. Recently, many have focused on the processes of disturbances and the evolutionary significance of such events. This shifted emphasis has inspired studies in diverse systems. The phrase "patch dynamics" (Thompson, 1978) describes their common focus. The Ecology of Natural Disturbance and Patch Dynamics brings together the findings and ideas of those studying varied systems, presenting a synthesis of diverse individual contributions.
Assessment of a Model of Forest Dynamics Under Contrasting Climate and Disturbance Regimes in the Pacific Northwest by Richard T. Busing,Allen M. Solomon Pdf
Emulating Natural Forest Landscape Disturbances by Ajith H. Perera,Lisa J. Buse,Michael G. Weber Pdf
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.
The Effects of Wind Disturbance on Temperate Rain Forest Structure and Dynamics of Southeast Alaska by Gregory Jay Nowacki,Marc G. Kramer Pdf
Wind disturbance plays a fundamental role in shaping forest dynamics in southeast Alaska. Recent studies have increased our appreciation for the effects of wind at both large and small scales. Current thinking is that wind disturbance characteristics change over a continuum dependent on landscape features (e.g. exposure, landscape position, topography). Data modeling has revealed the existance of fistinct wind disturbance regimes, grading from exposed landscapes where recurrent, large-scale wind events prevail to wind-protected landscapes where small-scale canopy gaps predominate. Emulating natural disturbances offers a way to design future management plans and silvicultural prescriptions consistent with prevailing ecological conditions.
Managing Forests as Complex Adaptive Systems by Christian C. Messier,Klaus J. Puettmann,K. Dave Coates Pdf
The emerging concepts of complexity, complex adaptive system (CAS) and resilience to forest ecology and management are linked in this new book. It explores how these concepts can be applied in various forest biomes of the world with their different ecological, economic and social settings, and history.
Dendroecology by Mariano M. Amoroso,Lori D. Daniels,Patrick J. Baker,J. Julio Camarero Pdf
Dendroecologists apply the principles and methods of tree-ring science to address ecological questions and resolve problems related to global environmental change. In this fast-growing field, tree rings are used to investigate forest development and succession, disturbance regimes, ecotone and treeline dynamics and forest decline. This book of global scope highlights state-of-the-science dendroecological contributions to paradigm-shifts in our understanding of ecophysiology, stand dynamics, disturbance interactions, forest decline and ecosystem resilience to global environmental change and is fundamental to better managing our forested ecosystems for the full range of ecosystem goods and services that they provide.
Understanding Forest Disturbance and Spatial Pattern by Michael A. Wulder,Steven E. Franklin Pdf
Remote sensing and GIS are increasingly used as tools for monitoring and managing forests. Remotely sensed and GIS data are now the data sources of choice for capturing, documenting, and understanding forest disturbance and landscape pattern. Sitting astride the fields of ecology, forestry, and remote sensing/GIS, Understanding Forest Disturbance and Spatial Pattern: Remote Sensing and GIS Approaches takes you through the general biological or landscape ecological context of forest disturbance to remote sensing and GIS technological approaches and pattern description and analysis, with compelling applied examples of integration and synthesis. Written by experts, peer-reviewed to adhere to the strictest standards and highest quality criteria, these chapters discuss natural and human-caused forest change and consider factors such as biological setting, monitoring approaches, scale issues, and pattern analysis. The book explores forest disturbance and spatial pattern from an ecological point-of-view within the context of structure, function, pattern, and change. It concludes with a summary of the issues related to detection and mapping of forest disturbances with remotely sensed and GIS data. The authors elucidate how the elements presented, from ecological underpinnings, data considerations, change detection method, and pattern analysis, combine into a problem solving, information generating approach. You may find this subject covered briefly in a small sub-section in remote sensing forestry texts, or in limited technical detail in the ecology literature. The in-depth, detailed information provided in this book allows you to develop an understanding of the application of BOTH remote sensing and GIS technologies to forest change and the impacts of fire, insect infestation, forest harvesting, and other potential change influences – such as extreme weather events. This book provides guidance on how to master the challenges of capturing and characterizing forest disturbance and spatial patterns.
Natural Disturbances and Historic Range of Variation by Cathryn H. Greenberg,Beverly S. Collins Pdf
This book discusses the historic range of variation (HRV) in the types, frequencies, severities and scales of natural disturbances, and explores how they create heterogeneous structure within upland hardwood forests of the Central Hardwood Region (CHR). The book was written in response to a 2012 forest planning rule which requires that national forests to be managed to sustain ‘ecological integrity’ and within the ‘natural range of variation’ of natural disturbances and vegetation structure. Synthesizing information on HRV of natural disturbance types, and their impacts on forest structure, has been identified as a top need.
Plant Disturbance Ecology by Edward A. Johnson,Kiyoko Miyanishi Pdf
Disturbance ecology continues to be an active area of research, having undergone advances in many areas in recent years. One emerging direction is the increased coupling of physical and ecological processes, in which disturbances are increasingly traced back to mechanisms that cause the disturbances themselves, such as earth surface processes, mesoscale, and larger meteorological processes, and the ecological effects of interest are increasingly physiological. Plant Disturbance Ecology, 2nd Edition encourages movement away from the informal, conceptual approach traditionally used in defining natural disturbances and clearly presents how scientists can use a multitude of approaches in plant disturbance ecology. This edition includes nine revised chapters from the first edition, as well new, more comprehensive chapters on fire disturbance and beaver disturbance. Edited by leading experts in the field, Plant Disturbance Ecology, 2nd Edition is an essential resource for scientists interested in understanding plant disturbance and ecological processes. Advances understanding of natural disturbances by combining geophysical and ecological processes Provides a framework for collaboration between geophysical scientists and ecologists studying natural disturbances Includes fully updated research with 5 new chapters and revision of 11 chapters from the first edition
Disturbance Ecology by Thomas Wohlgemuth,Anke Jentsch,Rupert Seidl Pdf
This edited work presents a multi-faceted view on the causes and consequences of disturbance in ecosystems. Vegetation can be affected by a variety of different disturbances such as wind, floods, fire, and insect attack, leading to an abrupt change in live biomass. Disturbance is a motor of vegetation dynamics, but also sensitive to climate change and poses a challenge for ecosystem management. Readers will discover the global distribution of disturbance regimes and learn about the importance of disturbances for biodiversity and the evolution of plant and animal life. The book provides a Central European perspective on disturbance ecology, and addresses important disturbance agents such as fire, wind, avalanches, tree diseases, insect defoliators, bark beetles and large herbivores in dedicated chapters. It furthermore includes chapters on anthropogenic disturbances in forests and grasslands. The impact of climate change on disturbance regimes and approaches to address disturbance risks in ecosystem management are discussed in concluding chapters. Within the 18 chapters 14 textboxes highlight current topics of disturbance ecology and provide deeper methodological insights into the field. Disturbances strongly shape our landscapes and maintain our biodiversity. A better understanding of their ecology is thus fundamental for contextualizing the dynamic changes in our environment. This book is a valuable resource for students and practitioners interested in disturbances and their management.
