The impact of treatment on mountain pine beetle infestation
The spatial extent of the current mountain pine beetle epidemic in western Canada has highlighted the need to understand the efficacy of treatment strategies. We investigate the effect of five direct-control treatments applied in central British Columbia during a mountain pine beetle epidemic. Using point data from GPS helicopter surveys and kernel density estimators, efficacy was explored thro...
متن کاملMountain Pine Beetle Epidemiology in Lodgepole Pine
The following brief synthesis of mountain pine beetle epidemiology is based on host-beetle interaction. In the first part I briefly describe the relationship between the dynamics of lodgepole pine and mountain pine beetle. The second part describes the phases in the infestation cycle and their main characteristics. This synthesis is based on published information on infestation behaviour in wes...
متن کاملSpatial scaling of mountain pine beetle infestations.
1. The relationship between occupancy and spatial contagion during the spread of eruptive and invasive species demands greater study, as it could lead to improved prediction of ecosystem damage. 2. We applied a recently developed model that links occupancy and its fractal dimension to model the spatial distribution of mountain pine beetle infestations in British Columbia, Canada. We showed that...
متن کاملImpact of Forest Fragmentation on Patterns of Mountain Pine Beetle-Caused Tree Mortality
The current outbreak of mountain pine beetle, Dendroctonus ponderosae Hopkins, has led to extensive tree mortality in British Columbia and the western United States. While the greatest impacts of the outbreak have been in British Columbia, ongoing impacts are expected as the outbreak continues to spread eastward towards Canada’s boreal and eastern pine forests. Successful mitigation of this out...
متن کاملImpact of mountain pine beetle induced mortality on forest carbon and water fluxes
Quantifying impacts of ecological disturbance on ecosystem carbon and water fluxes will improve predictive understanding of biosphere—atmosphere feedbacks. Tree mortality caused by mountain pine bark beetles (Dendroctonus ponderosae) is hypothesized to decrease photosynthesis and water flux to the atmosphere while increasing respiration at a rate proportional to mortality. This work uses data f...
