Abstract Silvicultural strategies to reduce tree losses from mountain pine beetle attacks typically seek to reduce relative densities in order to increase tree resistance and thus lower potential beetle attacks. For lodgepole pine stands, however, the tree mortality/relative density relationship is nonlinear. We describe three relative density zones corresponding to different levels of resistance to beetle attack. In the density management of young lodgepole pine stands, we propose two alternative strategies to reduce future losses from mountain pine beetle attacks. The first density management regime involves a low density (i.e., SDI < 140) throughout the rotation. The second density management regime is designed to maintain relative density above a threshold level (i.e., SDI > 245). West. J. Appl. For. 11(2):50-53.

The 1960S

Extensive outbreaks of the mountain pine beetle ( Dendroctonus ponderosae Hopkins) will alter the structure of many stands that will likely be attacked again before experiencing a stand-replacing fire. We examined a stand of lodgepole pine ( Pinus contorta var. latifolia Engelm. ex S. Watson) in Grand Teton National Park currently experiencing a moderate-level outbreak and previously attacked by mountain pine beetle in the 1960s. Consistent with published studies, tree diameter was the main predictor of beetle attack on a given tree, large trees were preferentially attacked, and tree vigor, age, and cone production were unimportant variables for beetle attack at epidemic levels. Small trees killed in the stand were killed based mainly on their proximity to large trees and were likely spatially aggregated with large trees as a result of the previous outbreak. We concluded that the driving factors of beetle attack and their spatial patterns are consistent across outbreak severities but that stand structure altered by the previous outbreak had implications for the current outbreaks in the same location. This study should catalyze additional research that examines how beetle-altered stand structure affects future outbreaks — an important priority for predicting their impacts under climate change scenarios that project increases in outbreak frequency and extent.
