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 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.

Available in PDF, EPUB and Kindle. Book excerpt: The mountain pine beetle (MPB) (Dendroctonus ponderosae) has killed millions of acres of pines throughout the western United States in recent years. Active control of the beetle has been hindered by the inability to detect infested trees prior to obvious visual signs. With sponsorship from the Forest Service, U.S. Department of Agriculture (USFS) Remote Sensing Steering Committee, the Remote Sensing Applications Center in collaboration with the Black Hills National Forest (NF), conducted a study to determine the feasibility of pre-visual detection of MPB-infested ponderosa pine by analyzing a time series of 26 high-resolution, 8-band, multispectral WorldView-2 (WV2) images of the Black Hills NF. Based on spectral and trend analyses of the time series data, the first sign of detection occurred around mid-March to April. Unfortunately, the newly attacked trees could not be detected early enough for the management goals of the Black Hills NF. Therefore, the emphasis of the project shifted to developing a semi-automated method to map the red-attack stage of the trees from high-resolution aerial photography and SPOT 6 imagery. The red-attack trees were mapped from the aerial photography using eCognition software across an area of approximately one million acres. In many areas, the results were exceptional, with very few errors; however, in areas of sparse or thinned forest, significant errors of omission and commission occurred. Despite the errors, the semi-automated process may still provide sufficient benefit to reduce the time and cost of mapping the trees as compared to traditional manual delineation methods.
Download or read book Linking Survey Detection Accuracy with Ability to Mitigate Populations of Mountain Pine Beetle written by S. Coggins and published by . 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.
Download or read book Working Paper Monitoring Tree level Insect Population Dynamics with Multi scale and Multi source Remote Sensing written by Michael A. Wulder and published by . 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.

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.

This book was released on 2007 with total page 50 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 examines mountain pine beetle (Dendroctonus ponderosae Hopkins) dispersal processes, which drive the spatial and temporal development of outbreaks. Understanding these processes is important for modelling future infestations and guiding forest management decisions. In this study, the spatial patterns of red- and green-attacked trees were used to characterize the spatial-temporal nature of dispersal. Research aims were to detect evidence of dispersal based on the distance and direction between red- and green-attacked tree clusters, determine how dispersal patterns change at different stages of infestation, and to detect landscape variables influencing the observed dispersal patterns. Variables explored included Biogeoclimatic ecosystem classification (BEC), topography, and the local population of susceptible hosts.--Includes text from Government of Canada publications site and from document.

Available in PDF, EPUB and Kindle. Book excerpt: Pine forests face a global threat of pine wilt disease, which is being spread by vector beetles carrying pathogenic nematodes from dead trees to healthy ones. Among the host pines there are varying degrees of susceptibility, and nematode strains also contain a variety of virulences, both of which factors help to determine whether infected host trees will die or survive. As well, biotic and abiotic environmental factors influence the fate of infected trees. This book describes the history of the disease, pathogenic nematodes, vector beetles, the etiology and ecology of the disease, microorganisms involved, and control methods that utilize host resistance and biological control agents. Concrete, comprehensive, and the most up-to-date knowledge about this worldwide forest epidemic is presented for readers, enabling them to understand the nature and epidemic threat of pine wilt disease.
