The main effect of a mountain pine beetle infestation is pine mortality in mature stands being disproportionately greater in the larger diameter classes. Concerns with regards to economic operability, resource management costs and future timber supply, include the rate of deterioration of killed trees, the structure and growth of the residual stands, and the establishment and quality of natural regeneration. In addition, the changes in stand structure, species composition, the amount of coarse woody debris following infestations and the resulting changes in stand microclimate, have potentially important implications for ecological succession, biomass accumulation and forest-fire interactions. All of these concerns are heightened by the occurrence of mountain pine beetle epidemics at the landscape scale (as evidenced by the current epidemic in central British Columbia) and the relatively large variation in tree mortality as affected by tree, stand, site and climatic factors. The objective of the studies is to establish baseline information on the economic and ecological characteristics of beetle damaged stands within a selection of biogeoclimatic regions of British Columbia.
