Book Exploring the Spatial temporal Interaction of Mountain Pine Beetle Infestations

Download or read book Exploring the Spatial temporal Interaction of Mountain Pine Beetle Infestations written by Colin Robertson and published by . 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.

Book Using Conditional Spatial Randomization to Identify Insect Infestation Hot Spots

Download or read book Using Conditional Spatial Randomization to Identify Insect Infestation Hot Spots written by Trisalyn Nelson and published by . This book was released on 2007 with total page 28 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. The purpose of this paper is to explore patterns of mountain pine bettle infestations using a conditional randomization procedure that recognizes that the probability of infestation occurrence is not spatially uniform.--Includes text from Government of Canada publications site and from document.

Book Growth of Ponderosa Pine Stands in Relation to Mountain Pine Beetle Susceptibility

Download or read book Growth of Ponderosa Pine Stands in Relation to Mountain Pine Beetle Susceptibility written by and published by . This book was released on 1999 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten-year diameter and basal area growth were determined for partially cut stands at 4 locations. Average diameters in the partially cut plots generally increased by 1 inch or more, while average diameter in the uncut controls increased by 0.9 inches or less. Individual tree growth is discussed in relation to potential susceptibility to mountain pine beetle infestation. Basal area increases ranged from 0.9 to 1.9 ft2/acre/ yr in partially cut plots, while basal area increases in the control plots ranged from 0.4 to 1.4 ft2/acre/yr. Endemic mountain pine beetle infestations and snow breakage accounted for most of the mortality on the plots, which decreased the residual basal area and basal area growth. Increases in basal area are used to estimate the length of time required for various stand densities to reach the susceptibility thresholds for mountain pine beetle infestation. Stand marking may influence future susceptibility to beetle infestations.

Book The Mountain Pine Beetle

Download or read book The Mountain Pine Beetle written by Pacific Forestry Centre and published by . This book was released on 2006 with total page 304 pages. Available in PDF, EPUB and Kindle. 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.
