Book Description
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.
