Provincial MPB maps

Mortality survey results and maps

Each spring, Alberta conducts mountain pine beetle (MPB) mortality surveys to assess the number of pine beetle larvae that survived the previous winter. Surveyors cut core samples from trees and compare the number of dead versus live beetle larvae under the bark.

The surveys help to set beetle control priorities in Alberta by forecasting MPB populations for the coming year – they do not account for any potential long distance movement of beetles from British Columbia, Federal mountain parks or heavily infested areas of Alberta.
