This book was released on 2009 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the period 1999 to 2006, the mountain pine beetle impacted an estimated 10.1 million hectares of pine forest in British Columbia, Canada. Surveys to detect the location, size, and impact of infestations are conducted from field, airborne, and satellite perspectives. Importantly, the differing survey approaches characterize the infestation over dissimilar spatial scales (i.e., trees, stands, landscapes), and with varying levels of detection accuracy. In this report, the authors provide background for understanding differing survey approaches, the nature of the information generated, the resultant detection accuracies that may be expected, and the link between survey accuracy and the ability to mitigate a given mountain pine beetle infestation.--Document.

Book excerpt: "This book presents a synthesis of published information on mountain pine beetle (Dendroctonus ponderosae Hopkins [Coleoptera: Scolytidae]) biology and management with an emphasis on lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests of western Canada. Intended as a reference for researchers as well as forest managers, the book covers three main subject areas: mountain pine beetle biology, management, and socioeconomic concerns. The chapters on biology cover taxonomy, life history and habits, distribution, insect-host tree interactions, development and survival, epidemiology, and outbreak history. The management section covers management strategy, survey and detection, proactive and preventive management, and decision support tools. 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 Mountain Pine Beetle Attack in Ponderosa Pine Comparing Methods for Rating Susceptibility written by David C. Chojnacky and published by . This book was released on 2000 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two empirical methods for rating susceptibility of mountain pine beetle attack in ponderosa pine were evaluated. The methods were compared to stand data modeled to objectively rate each sampled stand for susceptibly to bark-beetle attack. Data on bark-beetle attacks, from a survey of 45 sites throughout the Colorado Plateau, were modeled using logistic regression to estimate the probability of attack on individual trees from tree and stand variables. The logistic model allowed flexibility to easily scale results up to a stand level for comparison to the empirical methods. The empirical method, developed by Munson and Anhold, most closely correlated to the logistic regression results. However, the Munson/Anhold method rated all 45 study sites as either moderately or highly susceptible to bark-beetle attack, which raises concern about its lack of sensitivity. Future work on evaluating risk of bark-beetle impact should consider more than stand characteristics.

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.

This book was released on 2006 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mountain pine beetle (Dendroctonus ponderosae Hopkins) is the most destructive insect of mature pine forests in western North America. From a forest management perspective, estimates of the location and extent of mountain pine beetle red-attack are critical; however, the degree of precision required for these estimates varies according to the management objective under consideration and the nature of the mountain pine beetle infestation. This report describes a study to explore the potential of single-date SPOT multispectral imagery to detect and map mountain pine beetle red-attack damage in an area with relatively low infestation levels using an automated classification procedure. In doing so, issues unique to SPOT, and the potential offered by the higher spatial resolution of SPOT compared with Landsat, could be identified. The viability of SPOT as an alternative data source to Landsat could then be assessed.
