Book excerpt: In 2007, a multi-year connectivity modelling experiment was initiated to better understand the movement potential of mountain pine beetle (MPB) in Alberta and Saskatchewan pine forests. In the first year, spatial models of highly susceptible pine forest connectivity were developed for Alberta and Saskatchewan. The following year, the study focused solely on Alberta pine forests as our investigation turned to examine the effect that different pine species have on the connectivity model. In the third year (2009-10), the influence of climate on the landscape connectivity in Alberta was explored. To investigate the impacts of possible climate changes, minimum planar graphs were developed for the Alberta pine forests based on a modified stand susceptibility index. It was found that the stand susceptibility index most closely reflected observed MPB spread patterns when there were no climatic limitations in the model. A preliminary verification of the connectivity model was also performed. Using the model to determine expected 2009 MPB locations based on observed 2008 MPB source locations, both visual and statistical comparisons were performed to determine how well the model matched observed MPB spread. Generally, MPB were preferentially selecting closely connected habitat, but some of the direction of spread did not follow expected patterns. Some factor other than habitat connectivity (such as wind direction during MPB flight or topography) was influencing MPB spread: this warrants further exploration.
Book Synopsis Incorporating Present and Future Climatic Suitability Into Decision Support Tools to Predict Geographic Spread of the Mountain Pine Beetle by : Terence Leckie Shore
Download or read book Incorporating Present and Future Climatic Suitability Into Decision Support Tools to Predict Geographic Spread of the Mountain Pine Beetle written by Terence Leckie Shore and published by . This book was released on 2008 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main goal of this project was to adapt existing mountain pine beetle (MPB) decision-support tools to incorporate climatic suitability information to refine the spatial characterization of present climate and to support assessments of future climate. These tools include susceptibility and risk rating systems, the MPBSim stand-scale MPB population model, the landscape-scale SELES-MPB population model, and graph-based connectivity methods. We made significant advances on all of these, resulting in a suite of tools with increased capabilities and generality. During the course of this project, we also provided decisions support in the specific areas of study, in particular Dawson Creek and central-western Alberta. The basis of the climatic suitability was the work of A. Carroll et al. (2004) which produced estimates of MPB climatic suitability in five classes across western Canada, for historical, existing and future climates. Future climate information was derived from global circulation models such as the CGCM model. They input general climate information into the BioSim tool, in conjunction with topography and other variables relevant to downscaling for MPB, to produce the MPB climatic suitability maps. We used these maps to create an adaptation of the MPB susceptibility and risk rating system that replaced the coarser location factor (based on latitude, longitude and elevation) with MPB climatic suitability. It is important to note that the MPB climatic suitability refers only to climatic conditions relevant for MPB survival and reproduction, while the susceptibility rating system incorporates pine host information. We also modified MPBSim, a stand-scale population model, to utilize the MPB climatic suitability information. In previous applications, MPBSim was adapted to local conditions via a calibration process using local weather information. In some senses, this calibration process resulted in a reasonably precise adjustment to local conditions. However, it was also fairly labour intensive and didn't account as well for spatial variability. Our approach here was to use climatic suitability to both increase spatial precision as well as produce outputs that can be readily adapted to different stand and landscapes. The SELES-MPB landscape-scale population model scales MPBSim dynamics to broad spatial areas. We modified this tool to utilize the revised MPBSim output. This supports more rapid adaptation to other landscapes, as well as allows examination of potential effects of future climate. Our Dawson Creek analysis indicated that beetle management in the Dawson Creek area could significantly affect the spread and impact of the beetle outbreak over the next 10 years, provided that high levels of fell and burn and survey efforts are maintained. Estimated impacts are significantly affected by external pressure from the main outbreak, as estimated using the provincial-scale BCMPB projection. If mountain pine beetle populations can be held low until the main outbreak subsides (which will likely occur within the next five years due to availability of hosts), management should be able to curtail major losses in the Dawson Creek area. In areas with new or no current MPB attack, especially in areas within the expanding range, there is relatively high uncertainty of how the MPB may spread, such as in central-western Alberta. We developed graph-based connectivity methods to assess the spatial pattern of high susceptibility hosts across broad regions, under historic, existing or future climates. This information has been useful to help prioritize and rank stands for treatment in areas of imminent or future risk, and to identify areas for which treatment has no benefit.

Book Synopsis Impacts of Climate Change on Range Expansion by the Mountain Pine Beetle by : Allan Carroll
Download or read book Impacts of Climate Change on Range Expansion by the Mountain Pine Beetle written by Allan Carroll and published by . This book was released on 2006 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mountain pine beetle, Dendroctonus ponderosae (Hopkins) (MPB), is one of the most significant sources of mortality in mature pine forests in western North America. Despite its significant distribution, the current latitudinal and elevational range of MPB in western Canada is not restricted by the availability of suitable host trees but instead has been limited by climate. It is anticipated that under global warming, former climatically hostile environments will become climatically benign, allowing MPB to significantly expand its range. This study was initiated to investigate if there has been a shift in climatically benign habitats for MPB during the past three decades, if MPB populations have expanded into these new habitats, and what may be the range of climatically benign habitats in the future.

Book Synopsis Social Dimensions of Community Vulnerability to Mountain Pine Beetle by : Norah MacKendrick
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.

Available in PDF, EPUB and Kindle. Book excerpt: Today, climate change and rapid ecological change are impacting our ecosystems and landscapes in numerous, often surprising ways. These changes result in social, cultural, ecological, and economic shifts, as exemplified in the climate-exacerbated mountain pine beetle (MPB) outbreak in British Columbia. Recently, scientific communities have boosted calls for ¢usable science.o By interviewing leading MPB scientists, I ask, ¢How are scientists and their institutions responding to rapid ecological change?o Numerous factors shape MPB science?institutional support, funding, and values?and these factors enable and constrain effective relationships and ultimately, useful science, in response to the outbreak. Results suggest that while science and scientific institutions change slowly, and while relationships between MPB science and policy are characterized as tenuous, there are signs that crossing institutional boundaries (such as the TRIA Network) contributes to producing science that is more effective for responding to rapid ecological change.

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.
