This book was released on 2008 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-term monitoring of the rate of change of mountain pine beetle (Dendroctonus ponderosae Hopkins) populations requires detailed tree-level information over large areas. This information is used to assess the status of an infestation (e.g., increasing, stable, or decreasing), and to select and evaluate mitigation approaches. In this research project, the authors develop and demonstrate a prototype monitoring system, which enables the extrapolation of tree-level estimates of beetle damage from field data to a larger study area using a double sampling approach, and multi-scale, multi-source, high spatial resolution remotely sensed data. The project study area encompasses over 6 million ha and is located at the leading edge of an ongoing mountain pine beetle epidemic along the provincial border between British Columbia and Alberta, within the Dawson Creek Timber Supply Area (TSA) of British Columbia and the Northwest Boreal Forest Management Unit in Alberta.--Document.
Download or read book Detecting and Mapping Mountain Pine Beetle Red attack Damage with SPOT 5 10 m Multispectral Imagery written by Joanne White and published by . 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.

This book was released on 2007-01-01 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: An accuracy assessment is considered the best way to demonstrate the effectiveness with which different data sources and methods may be used to map mountain pine beetle red attack damage from remotely sensed data. Simply reporting overall accuracy, however, does not provide sufficient context to evaluate the map product and may misconstrue the accuracy with which red attack damage is detected and mapped. This publication made several recommendations regarding accuracy assessment in the context of mountain pine beetle red attack detection and mapping.--Document.
Download or read book A Procedure for Mapping and Monitoring Mountain Pine Beetle Red Attack Forest Damage Using Landsat Imagery written by and published by . This book was released on 2006 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote sensing is a useful technology for detecting and mapping the red attack stage of a mountain pine beetle infestation. Provided appropriate imagery is selected to coincide with the manifestation of the red attack damage, the damage can be mapped in an accurate and timely fashion using Landsat Thematic Mapper or Enhanced Thematic Mapper Plus imagery and change detection methods. This report describes a detailed procedure for using multiple dates of Landsat imagery to generate information products indicating the location and extent of mountain pine beetle red attack damage. The accuracy of this procedure is assessed and reported using more detailed forest health survey information at three sites in British Columbia. Also documented in this report is an optimal approach for Landsat scene selection, a summary of the level of effort required to apply the procedure described herein, and recommendations for potential improvements to the mapping procedure. Details on data acquisition, image pre-processing, image analysis, and accuracy assessment are included to facilitate the implementation for the mapping procedure in an operational context.

This book was released on 2010 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This working paper presents a prototype model to estimate the amount of lodgepole pine affected by a mountain pine beetle (MPB) attack. After employing digital aerial image interpretation to determine species composition, diameter at breast height (DBH), and the severity of attack, and lidar data to measure stand height, species-specific equations were used to estimate volumes killed.--Document.

Available in PDF, EPUB and Kindle. Book excerpt: This publication supplements Wood & Bright's 1992 catalogue of the world's Scolytidae and Platypodidae (bark beetles), updating the taxonomy of these two families to nearly the end of 1995 and including all known literature references to the end of 1994 (plus references to articles missed in the earlier bibliography). References which provide new information on taxonomy, host plants, or biology of a species are also included. The format of the supplement closely follows that of the 1992 catalogue. Each genus & species is listed with its page number from that catalogue; additional information on figures, distribution, hosts, and references to other subject areas are given. The publication also includes lists of host plants, arranged by scientific name, and the beetles attacking them.
