This book was released on 2008 with total page 68 pages. 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. Using an established modelling framework, the authors of this report conducted a scenario analysis exercise designed to explore opportunities to mitigate the ecological and economic impacts of mountain pine beetle (MPB) salvage for two possible outbreak severity levels in Canfor's Tree Farm License (TFL) 48 in northeastern British Columbia. This data was used to address the following questions: 1) What are the potential short and long-term impacts of different levels of MPB attack for indicators of sustainable forest management in northeastern British Columbia?; and 2) Assuming a reduction in landscape-level ecological and economic stocks, what management options are available that will maintain a profitable harvesting profile while sustaining ecological indicators? Additionally, results from the analysis were evaluated in the context of a range of ecological and economic indicators.--Includes text from Government of Canada publications site and from document.
Download or read book Mountain Pine Beetle Impacts on Channel Morphology and Woody Debris in Forested Landscapes written by Marwan Hassan and published by . This book was released on 2008 with total page 46 pages. 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 (MPB) epidemic. The objective of this report was to determine watershed-scale impacts of mountain pine beetles by comparing channel conditions and the woody debris budget in watersheds infested by the MPB with those from similar old-growth forests with pre-infestation channel and riparian data. The use of a woody debris budget directly links large-scale lodgepole pine mortality to stream challen and piparian processes and conditions at the landscape level. Eighteen watersheds in the Sub-Boreal Spruce and Sub-Boreal--Pine Spruce biogeoclimatic zones were considered. The results are used to generate regionally and locally relevant best management practices that will guide operational planning in landscapes impacted by the MPB.--Includes text from Government of Canada publications site and from document.

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 main purpose of this study was to apply and refine a model methodology to evaluate the effectiveness of landscape-scale bark beetle-management activities in reducing losses to mountain pine beetle, and to analyze the potential spread of the beetle across the study area. Specifically, the goal of this project was to address the question: what would be the likely trajectory and impacts from the current beetle outbreak under a range of alternative beetle-management regimes?
Download or read book Preliminary Risk Rating for Mountain Pine Beetle Infestation of Lodgepole Pine Forests Over Large Areas with Ordinal Regression Modelling written by Colin Robertson and published by . This book was released on 2009 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: In western Canada, the operational risk rating system for mountain pine beetle is based on biological knowledge gained from a rich legacy of stand-scale field studies. Owing to the large spatial and temporal extents of the current epidemic, new research into large-area mountain pine beetle processes has revealed further insights into the landscape-scale characteristics of beetle infested forests. This research evaluates the potential for this new knowledge to augment an established system for rating the short-term risk of tree mortality in a stand due to mountain pine beetle.--Publisher's website.

The chapters on socioeconomic aspects include an economic examination of management programs and the utilization of post-beetle salvage timber in solid wood, panelboard, pulp and paper products."--Publisher's description.
Download or read book Modeling the Effect of Landscape Pattern on Mountain Pine Beetles written by Josie Hughes and published by . This book was released on 2006-01-01 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite ecological and management importance, little is known about the effect of forest landscape structure on the spread of mountain pine beetles (Dendroctonus ponderosae Hopkins). The general prediction from published literature is that forest fragmentation at some scale might slow the spread of infestations. However, mountain pine beetle dispersal ecology is complicated by requirement for attack en masse and a pheromone-based communication system that facilitates this aggregation process. One interesting possibility is that infestations might spread more slowly over habitat gaps across which beetles cannot communicate. To investigate this possibility, the authors developed an individual-based model of mountain pine beetle dispersal, aggregation and attack, and performed simulation experiments to explore the effects of habitat patch size, habitat compaction, communication distance, and flight behaviour on the spread rate and final extent of infestations.

This book was released on 2008 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report outlines the objectives, study design, methods of data collection, and other details relevant to the establishment of Experimental Project (EP) 1369: A Framework for Documenting the Effects of the Mountain Pine Beetle in Sub-boreal Forests of Northern British Columbia. In 1995 through 1997, 48 plots were established in mature pine leading stands affected by mountain pine beetle (MPB) (38 plots) and MPB followed by wildfire (10 plots). All plots will remain unharvested, and are designed to examine ecological changes subsequent to these disturbances. The information from these plots will inform science on what ecological changes result from these disturbances in the sub-boreal forest landscape, and will provide critical information (such as growth rate of live understorey) to land managers."--Document.

This book was released on 2007 with total page 24 pages. 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. It summarizes the results of a study on the landscape variation in lodgepole pine constitutive defences, primarily measured as resin production, but also as phloem monoterpene concentration. The response of pioneer mountain pine beetles to those defences is reviewed, measured by experimentally placing beetles on trees and by attacks of free-flying beetles; effects of beetle quality (size, condition) on the beetles' responses are also examined. Finally, the results on the dispersal of mountain pine beetles through a mature lodgepole pine stand and a burned stand are presented.--Includes text from Government of Canada publications site and from document.

Thirty presentations were given describing the current mountain pine beetle situation (in British Columbia, Alberta and the western United States) and its management and economic implications. Researchers presented the latest information on remote sensing, decision support systems, impacts on stand dynamics and wildlife, phytosanitary risks, climate change effects and preventive management as they relate to mountain pine beetle.
Download or read book Using Reconstructed Outbreak Histories of Mountain Pine Beetle Fire and Climate to Predict the Risk of Future Outbreaks written by Kathy J. Lewis and published by . This book was released on 2008 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mountain pine beetle (Dendroctonus ponderosae) is a native bark beetle of forests in BC, and there is documented evidence of outbreaks dating back to 1910. The current outbreak is substantially larger than past documented outbreaks, but the temporal scale of landscape-level forest change is much longer than the limited scope of recorded history. It is possible that the scale of management-induced changes to forest structure through fire suppression and forestry practices, and the mounting evidence of a changing climate, have contributed to an outbreak that is well outside the natural range of variation. The purpose of this project is to determine the magnitude and synchrony of historical beetle outbreaks in sub-boreal forests of central BC, and to relate those with climate factors and changes in fire regimes. Our focus is on the north-central part of BC, in areas that in the past have been less conducive to large scale mountain pine beetle outbreaks and less influenced by fire suppression, to determine whether or not the current outbreak in this area is due to the enormous population build-up alone, or whether changes in climate and/or fire regime have played a role. Using dendroecological methods, we have successfully reconstructed multiple mountain pine beetle outbreaks and calibrated our detection methods based on historical survey information. Our investigation of climate/outbreak relationships is underway and suggests that the timing of outbreaks in this area can be linked to periods of favourable climate for mountain pine beetle population growth.
Download or read book A Silvicultural Assessment of 10 Lodgepole Pine Stands After Partial Cutting to Reduce Susceptibility to Mountain Pine Beetle written by Roger J. Whitehead and published by . This book was released on 2007 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 15 years, selective cutting prescriptions have been applied by forest operations in southeastern British Columbia as part of a strategy to reduce landscape-level susceptibility to damage from mountain pine beetle outbreaks. The prescriptions have been applied in stands where maintenance of some mature forest cover is needed to meet management objectives for viewscapes, recreation and habitat or to hold some pine volume during periods of rising beetle activity until it is required or available for harvest. In this study, we examined 10 of these sites 5 to 14 years after harvest, and determined current stand composition and structure from direct sampling and pre- and post-treatment stand characteristics from stand reconstruction. We then related these characteristics to original treatment specifications; the volume removed during harvest and remaining on site after treatment; subsequent losses to wind, snow or bark beetle damage; current stocking status; radial growth rates of residual overstorey trees; and the nature of fuel complexes created and effects of treatment on potential fire behaviour.
Download or read book Information Need Driven Applications of Remotely Sensed Data for Mapping Mountain Pine Beetle Infestation at Landscape and Tree Levels written by Michael A. Wulder and published by . This book was released on 2007-01-01 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: When applying remotely sensed data, the information needs dictate the selection of data and analysis methods. Whether the scope of the application is over large areas or individual trees, a project typically must address logistical issues related to data selection and subsequent processing. Logistical issues include the scale at which the target must be measured (which will determine the appropriate sources of imagery), the attributes of interest, cost, timeliness, and repeatability. In this report, we ... synthesize approaches for detection and mapping of mountain pine beetle (Dendroctonus ponderosae Hopkins) red-attack damage with remotely sensed data, from a forest management and disturbance mitigation perspective.
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.
Download or read book Social Dimensions of Community Vulnerability to Mountain Pine Beetle written by Norah MacKendrick and published by . This book was released on 2005 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is widespread recognition that the outbreak of mountain pine beetle (MPB) will have significant social & economic impacts on forest-based communities. This report presents the result of a vulnerability assessment in 11 British Columbia and two Alberta communities located in regions experiencing various levels of MPB activity. To assess community vulnerability, the project first builds a vulnerability framework based on social science research in the areas of climate change, community capacity, hazards management, and risk perception, as well as on focus group meetings in five of the studied communities. Variables & indicators included in this framework are then measured & combined into a vulnerability index, with index scores assigned to each community. The spatial variation in vulnerability is further illustrated using geographic information systems analysis. The final assessment reflects that vulnerability is not only a function of physical exposure to beetle activity but also of various social, economic, & political factors.
