Except for wildfire suppression, management and utilization of lodgepole pine, Pinus contorta Dougl. ex Loud. var. latifolia Engelm., was essentially ignored in western Canada until quite recently. Consequently, the landscape now includes many older stands that matured without any silviculture to modify characteristics that make them susceptible to mountain pine beetle (Dendroctonus ponderosae Hopk. [Coleoptera: Scolytidae]) outbreaks. Susceptibility of this forest to extensive mountain pine beetle damage is an outcome of well-understood ecological relationships between the insect and its host acting on the current condition and distribution of the lodgepole pine forest. Whatever the management objective for a landscape unit, the key to reducing future damage is the same: consistent application of well-planned management to prevent infestations at the stand level and to relieve forest-level conditions that allow rapid expansion of local infestations to landscape-level outbreaks. This chapter describes the basic principles of preventive management based on key interactions between lodgepole pine and mountain pine beetle.
