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 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.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Occurring over multiple years and impacting an area over 13 million hectares to date, the current epidemic of mountain pine beetle (Dendroctonus ponderosae Hopkins) in British Columbia lends itself to the use of remote sensing technologies for monitoring purposes. Change detection procedures based upon spectral values are common; however, monitoring changes in landscape pattern presents opportunities for the generation of unique and ecologically important information. Furthermore, while the use of two images may provide the means to identify change, the use of more than two images affords the ability for long-term monitoring and characterization of processes such as change rates and dynamics. The initial component of this study consists of a literature review undertaken to investigate and summarize methods and applications of landscape pattern analysis using three or more image dates. This information was in turn used to make recommendations for the application of landscape pattern analysis of a time-series of remotely-sensed data to a case study involving mountain pine beetle infestation and timber harvesting. Following the review, we focused on the detection and monitoring of lodgepole pine stands in order to quantify the progression of forest fragmentation and loss of connectivity as a result of mountain pine beetle infestation and timber harvest. This was accomplished using a key set of landscape pattern indices applied to six Landsat satellite images spanning 1993 to 2006. Through our analysis we found that the impacts of the mountain pine beetle on forest spatial pattern consist of an increase in the number of forest patches, shape complexity, and patch isolation, and a decrease in forest patch size and interspersion. In addition, we determined that in a spatial context, mountain pine beetle infestation plays a significantly greater role in forest fragmentation and loss of connectivity than timber harvest. However, we also discuss the limitations of these find.
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.

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.

This book was released on 2008 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the broad range of mitigation strategies associated with the management of mountain pine beetle (Dendroctonus ponderosae Hopkins), including methods that are currently utilized or proposed for controlling beetle populations, the manner in which the effectiveness of these approaches is monitored and assessed and, finally, the role that remotely sensed data may play in a large-area monitoring system. To this end, the authors first review the goals of effectiveness monitoring and introduce a general classification system to clarify the purpose and practice of efficacy monitoring. Based on these principles, the review is then structured around effectiveness evaluations for managing forest pests, primarily mountain, southern, and western pine beetles throughout North America. These evaluations are grouped by management strategy: silvicultural treatments; prescribed burns; and the use of attractants, repellants, and insecticides. Finally, the authors propose the use of remotely sensed data as a complementary tool for monitoring changes in the extent and severity of mountain pine beetle damage across large areas.--Document.

Wulder and published by . This book was released on 2007-01-01 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: When applying remotely sensed data, the information needs dictate the selection of data and analysis methods. Whether the scope of the application is over large areas or individual trees, a project typically must address logistical issues related to data selection and subsequent processing. Logistical issues include the scale at which the target must be measured (which will determine the appropriate sources of imagery), the attributes of interest, cost, timeliness, and repeatability. In this report, we ... synthesize approaches for detection and mapping of mountain pine beetle (Dendroctonus ponderosae Hopkins) red-attack damage with remotely sensed data, from a forest management and disturbance mitigation perspective.
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.
