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. In this paper, an established decision support system was evaluated for operational use. Digital forest inventory and beetle-impact survey data were integrated in standard GIS software for rating susceptibility and risk of mountain pine beetle infestation. The beetle-impact data, collected over a three-year period, provided an opportunity to generate risk on a given year and compare it to attacks in the subsequent year.--Includes text from Government of Canada publications site and from document.

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.

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.

Download or read book Hydrologic Effects of Mountain Pine Beetle Infestation and Salvage harvesting Operations written by John F. Rex and published by . This book was released on 2009 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project was developed to identify a set of risk indicators to predict the risk of summer-ground loss at the watershed level within the Vanderhoof Forest District (VFD) and others, subsequent to the mountain pine beetle (MPB) infestation of lodgepole pine stands. This report was done in relation to the VFD annual cut of stands, and the following difficultings that operators found in running their equipment in wet versus dry soils in harvest years. Risk indicators were selected from available GIS information, aerial photographs, and local knowledge. The most effective indicators for predicting the risk of wet-ground areas at the watershed level were found to be lodgepole pine content, understorey, drainage density, sensitive soils, and the topographic index, all of whose values are available from provincial databases. The work includes information on materials and methods, results and discussion, the authors' conclusions, as well as recommendations.--Includes text from document.
Download or read book Biological Evaluation of Mountain Pine Beetle Activity on the Black Trout Analysis Area of South Park Ranger District Pike San Isabel National Forest and Comanche and Cimarron National Grasslands 2005 written by and published by . This book was released on 2005 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ponderosa pine mortality due to mountain pine beetle (MPB) activity has been detected in air and ground surveys of the Black Trout Analysis Area on the South Park District of the Pike-San Isabel National Forests and Comanche and Cimarron National Grasslands. The South Park Ranger District has proposed mechanical and prescribed burn silvicultural treatments on approximately 12,500 acres of National Forest Lands to salvage trees killed, to reduce MPB infestations, to reduce disease impacts and to reduce the potential for crown or high intensity wildfires within designated areas of the Black Trout Analysis Area.?Lakewood Service Center-Forest Health Management (LSC-FHM) personnel used aerial survey information and ground surveys to determine stand conditions and the level of beetle infestation in the Black Trout Analysis Area. Ground surveys included strip samples and systematic variable radius (VR) plot samples. Strip samples indicate MPB population trends by comparing the number of trees infested in 2004 and the number of MPB-killed trees in 2003. VR plots record stand density and tree diameter which is used along with available stand exam data to determine stand susceptibility.?Results indicate an increasing population trend in 4 of 9 units surveyed and a decreasing trend in 5 of the units where MPB had already killed many trees. Although many stands have already suffered high levels of mortality, there remains a high risk of infestation to all susceptible stands in the proposed treatment areas. Average stand diameters, age, tree density and elevation indicate that stands in the proposed treatment areas are either moderately or highly susceptible to MPB outbreaks.?Management actions to address the MPB infestation in the Black Trout Analysis Area are discussed. Sanitation and salvage of beetle infested trees and reducing stand density in the uninfested portions of the proposed treatment areas may help reduce MPB impacts and reduce stand susceptibility to MPB attack.
