Bark Beetle Responses to Stand Structure and Prescribed Fire at Blacks Mountain Experimental Forest, California, USA: 5-Year Data
Highly effective fire suppression and selective harvesting of large-diameter, fire-tolerant tree species, such as ponderosa pine (Pinus ponderosa
C. Lawson) and Jeffrey pine (P. jeffreyi
Balf.), have resulted in substantial changes to the structure and composition of interior ponderosa pine forests. Mechanical thinning and the application of prescribed fire are now commonly used to reduce fuel loads and restore late-seral conditions in interior ponderosa pine forests, but the propensity for some bark beetles (Coleoptera: Curculionidae, Scolytinae) to attack fire-injured trees has led to questions regarding how management objectives may be impacted by levels of delayed tree mortality attributed to bark beetle attack. In this study, we examined bark beetle responses to creation of mid-seral (low structural diversity; LoD) and late-seral (high structural diversity; HiD) forest structures at Blacks Mountain Experimental Forest, California, USA, during a five-year period following the application of prescribed fire (B).
