Plain Language Summary

Rapid changes in the distribution of the mountain pine beetle and the significant investments made by forest managers in response resulted in a request for a reassessment of the threat by the Canadian Council of Forest Ministers via the National Forest Pest Strategy.

This report summarizes the findings of the reassessment in 2010. Many of the predictions made in an initial assessment in 2007 have come true. The beetle continues to expand both its geographic and host range. It is persisting in areas once thought to be climatically unsuitable and is finding and attacking even sparse clusters of trees. It is now confirmed to be successfully reproducing in jack pine, a transcontinental pine species of the boreal forest. In addition to the potential impacts to forestry, an increase in tree mortality could aggravate the already high fire risk characteristic of pine forest types.

The rapid availability of diverse survey and research results and improved communications among professionals enabled by the risk analysis process offer jurisdictions new possibilities for evidence-based, adaptive policy decisions. The risk assessment process makes scientific analysis of response options more feasible than ever.
