In western Canada, the current outbreak of mountain pine beetle (Dendroctonus ponderosae) is of unprecedented proportions. Annual aerial overview surveys (AOS) are the primary means of accounting for ...
The spread of mountain pine beetle (MPB) depends on climate, weather, and topography, among other factors. In predicting the spread of the MPB in British Columbia, foresters should specifically consid...
The objective of this study was to gauge the effectiveness of using SPOT-5 10-m multispectral imagery to detect and map red-attack damage for an area near Cranbrook, British Columbia, Canada. A logist...
The mountain pine beetle epidemic has dramatically altered lodgepole pine forests in British Columbia, with potentially profound effects on wildlife and wildlife habitats. Forest managers should under...
A growing literature considers how the forest management community will have to adapt to future climate change impacts. Recently in this journal, Spittlehouse and Stewart presented a framework for pla...
