Book excerpt: The Canadian government announced the Mountain Pine Beetle Initiative (MPBI) in 2002 to address the socio-economic and ecological consequences of an epidemic of mountain pine beetle (Dendroctonus ponderosae Hopkins). The objective of this study was to establish baseline information on the ecological characteristics that occur at different stages of succession, resulting from mountain pine beetle disturbance at different time intervals. Key issues addressed by this study were: the post-beetle ecological character of stands; the ecological legacies that should be sought post-beetle; maintenance of ecological integrity in beetle-damaged landscapes; and the impacts of beetles on regeneration. This paper presents a study of stand conditions following two historic mountain pine beetle outbreaks events in the 1940s and 1980s. The study quantified structural and species composition of stands at different stages of succession (25 years and 65 years), and quantified the differences that occur in forest development between stands with and without disturbance by the beetle. It concludes with several recommendations for management of post-disturbance landscapes.
Book Synopsis Mountain Pine Beetle by : Fred L. Bunnell
Download or read book Mountain Pine Beetle written by Fred L. Bunnell and published by . This book was released on 2011 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document provides a synthesis of recently completed studies to assess the ecological consequences of forest management after attack by mountain pine beetle or other large-scale disturbances. Studies are assessed for their contributions to gaps in knowledge previously identified in the Mountain Pine Beetle Initiative Working Paper "Evaluating effects of large scale salvage logging for mountain pine beetle on terrestrial and aquatic vertebrates," which was published in 2004. This report focuses on studies developed through the federal Mountain Pine Beetle Initiative, the federal Mountain Pine Beetle Program, and the complementary BC Forest Science Program. Relevant information from other jurisdictions is sometimes included to augment those studies. Topics examined are: the impacts of beetle kill and salvage operations on habitat attributes; the impacts of beetle kill and salvage operations on attendant processes, such as snag fall rates, light interception, and snow accumulation; and the wildlife response to large-scale beetle outbreaks and management strategies. For each of these three topics, we provide a summary of: research to date; pertinent findings to date; and gaps in research.
Book Synopsis Historical Environmental Variation in Conservation and Natural Resource Management by : John A. Wiens
Download or read book Historical Environmental Variation in Conservation and Natural Resource Management written by John A. Wiens and published by John Wiley & Sons. This book was released on 2012-07-09 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: In North America, concepts of Historical Range of Variability are being employed in land-management planning for properties of private organizations and multiple government agencies. The National Park Service, U.S. Fish & Wildlife Service, Bureau of Land Management, U.S. Forest Service, and The Nature Conservancy all include elements of historical ecology in their planning processes. Similar approaches are part of land management and conservation in Europe and Australia. Each of these user groups must struggle with the added complication of rapid climate change, rapid land-use change, and technical issues in order to employ historical ecology effectively. Historical Environmental Variation in Conservation and Natural Resource Management explores the utility of historical ecology in a management and conservation context and the development of concepts related to understanding future ranges of variability. It provides guidance and insights to all those entrusted with managing and conserving natural resources: land-use planners, ecologists, fire scientists, natural resource policy makers, conservation biologists, refuge and preserve managers, and field practitioners. The book will be particularly timely as science-based management is once again emphasized in United States federal land management and as an understanding of the potential effects of climate change becomes more widespread among resource managers.

Book Synopsis Historic Range of Variability for Upland Vegetation in the Bighorn National Forest, Wyoming by : Carolyn B. Meyer
Download or read book Historic Range of Variability for Upland Vegetation in the Bighorn National Forest, Wyoming written by Carolyn B. Meyer and published by . This book was released on 2005 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: An approach for synthesizing the results of ecological research pertinent to land management is the analysis of the historic range of variability (HRV) for key ecosystem variables that are affected by management activities. This report provides an HRV analysis for the upland vegetation of the Bighorn National Forest in northcentral Wyoming. The variables include live tree density, dead tree (snag) density, canopy cover, abundance of coarse woody debris, species diversity, fire return intervals, the abundance of various diseases, the proportion of the landscape in different land cover types, and the degree of patchiness in the landscape. The variables were examined at the stand and landscape scales, using information available in the literature and USFS databases. High-elevation landscapes were considered separately from low-elevation landscapes. Much of the report pertains to forests dominated by lodge-pole pine, subalpine fir, and Engelmann spruce at high elevations, and by ponderosa pine, aspen, and Douglas-fir at lower elevations. We defined the HRV reference period for the BNF as approximately 1600 to 1890.

This book was released on 2005 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: An approach for synthesizing the results of ecological research pertinent to land management is the analysis of the historic range of variability (HRV) for key ecosystem variables that are affected by management activities. This report provides an HRV analysis for the upland vegetation of the Medicine Bow National Forest in southeastern Wyoming. The variables include live tree density, dead tree (snag) density, canopy cover, abundance of coarse woody debris, species diversity, fire return intervals, the abundance of various diseases, the proportion of the landscape in different land cover types, and the degree of patchiness in the landscape. The variables were examined at the stand and landscape scales, using information available in the literature and USFS databases. High-elevation landscapes were considered separately from low-elevation landscapes. Much of the report pertains to forests dominated by lodgepole pine, subalpine fir, and Engelmann spruce at high elevations, and by ponderosa pine and aspen at lower elevations. We defined the HRV reference period for the MBNF as approximately 1600 to 1860.
Book Synopsis Fire in the Forest by : Peter A. Thomas
Download or read book Fire in the Forest written by Peter A. Thomas and published by Cambridge University Press. This book was released on 2010-09-23 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: How destructive or beneficial are forest fires to wildlife? Should we be trying to reduce or increase the amount of fire in forests? How are forest fires controlled, and why does this sometimes fail? What effect will climate change have? These and many other questions are answered in this richly illustrated book, written in non-technical language. The journey starts in the long geological history of fire leading up to our present love-hate relationship with it. Exploring the physics of how a single flame burns, the journey continues through how whole forests burn and the anatomy of firestorms. The positive and negative ecological effects of fires are explored, from plants and wildlife to whole landscapes. The journey ends with how fires are controlled, and a look to the future. This book will be of interest to ecologists, biogeographers and anyone with an interest in forest fires and the role they play.

Available in PDF, EPUB and Kindle. Book excerpt: This study is part of a series of research papers that explore the biological, social, and economic aspects of British Columbia's mountain pine beetle epidemic. The objective of this study is to compare two different approaches for calculating beetle pressure, and to assess the impact these approaches have on the subsequent calculation of risk ratings. To meet this objective, beetle pressure was calculated using the traditional distance-based model, as well as using an alternative density-based model, implemented with a Voronoi tessellation generated from helicopter-GPS point survey data of known beetle infestation locations.--Includes text from document.

Book Synopsis Cascading Effects of Fire Exclusion in Rocky Mountain Ecosystems by : Robert E. Keane
Download or read book Cascading Effects of Fire Exclusion in Rocky Mountain Ecosystems written by Robert E. Keane and published by . This book was released on 2002 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The health of many Rocky Mountain ecosystems is in decline because of the policy of excluding fire in the management of these ecosystems. Fire exclusion has actually made it more difficult to fight fires, and this poses greater risks to the people who fight fires and for those who live in and around Rocky Mountain forests and rangelands. This paper discusses the extent of fire exclusion in the Rocky Mountains, then details the diverse and cascading effects of suppressing fires in the Rocky Mountain landscape by spatial scale, characteristic, and vegetation type. Also discussed are the varied effects of fire exclusion on some important, keystone ecosystems and human concerns.
Book Synopsis Animals' Influence on the Landscape and Ecological Importance by : Friedrich-Karl Holtmeier
Download or read book Animals' Influence on the Landscape and Ecological Importance written by Friedrich-Karl Holtmeier and published by Springer. This book was released on 2014-10-22 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: In its first English-language edition, this book introduces the many-faceted interactions of animal populations with their habitats. From soil fauna, ants and termites to small and large herbivores, burrowing mammals and birds, the author presents a comprehensive analysis of animals and ecosystems that is as broad and varied as all nature. Chapter 2 addresses the functional role of animals in landscape ecosystems, emphasizing fluxes of energy and matter within and between ecosystems, and the effects of animals on qualitative and structural habitat change. Discussion includes chapters on the role of animal population density and the impacts of native herbivores on vegetation and habitats from the tropics to the polar regions. Cyclic mass outbreaks of species such as the larch bud moth in Switzerland, the mountain pine beetle and the African red-billed weaver bird are described and analyzed. Other chapters discuss Zoochory – the dispersal of seeds by ants, mammals and birds – and the influence of burrowing animals on soil development and geomorphology. Consideration extends to the impact of feral domestic animals. Chapter 5 focuses on problems resulting from introduction of alien animals and from re-introduction of animal species to their original habitats, discusses the effects on ecosystems of burrowing, digging and trampling by animals. The author also addresses keystone species such as kangaroo rats, termites and beavers. Chapter 6 addresses the role of animals in landscape management and nature conservation, with chapters on the impact of newcomer species such as animals introduced into Australia, New Zealand and Europe, and the consequences of reintroduction of species to original habitat. It also discusses the carrying capacity of natural habit, public attitudes toward conversation and more. The final section ponders the effects of climate on interactions between animals and their habitats.
