Evaluating Satellite Imagery for Estimating Mountain Pine Beetle-Caused Lodgepole Pine Mortality: Current Status
Spatial accuracy in the detection and monitoring of mountain pine beetle populations is an important aspect of both forest research and management. Using ground-collected data, classification models to predict mountain pine beetle-caused lodgepole pine mortality were developed for Landsat TM, ETM+, and IKONOS imagery. Our results suggest that low-resolution imagery such as Landsat TM (30 m) is ...
متن کاملMonitoring soil disturbance on salvaged areas within the mountain pine beetle infestation using digital imagery
There is a concern that the accelerated timber harvest in the mountain pine beetle epidemic area of British Columbia (BC) could compromise long-term forest productivity if soils are unduly disturbed. Consequently, the Ministry of Forests, Lands and Natural Resources Operations (MFLNRO) developed a protocol using groundand image-based methods to assess the status of the forest soil resource in p...
متن کاملThe 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 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 کاملMapping Percent Tree Mortality Due to Mountain Pine Beetle Damage
The mountain pine beetle (Dendroctonus ponderosae Hopkins) is a pervasive and particularly destructive species of insect that has killed vast areas of conifers in western North America. To map large areas of infestation satellite imagery is often used because of its ability to cover large areas, but the spatial resolution often precludes fine-scale analysis. Furthermore, maps of insect-caused t...
