The threat from mountain pine beetle is substantial.

The Study

While there is widespread consensus among forest industry personnel that expenditures for controlling the mountain pine beetle are justified, there has been no formal assessment of the benefits. An analysis was conducted to determine the costs, and the social and economic benefits of the current bark beetle management program. The study also attempted to assess the impact of the mountain pine beetle control program on the use of non-timber resources associated with lodgepole pine forests. Timber supply modelling, interviews with specialists and stakeholders, and other techniques were used in the analysis. This brochure summarizes the study findings. A copy of the report is available, on request, from the B.C. Ministry of Forests, Forest Practices Branch in Victoria.

    The analysis compared the current mountain pine beetle program with a "no control" program in the Merritt and Morice timber supply areas. The results were then extrapolated to the province.

    Biogeoclimatic factors in Merritt favour intense infestations that expand quickly but only last for short periods. In Morice, development of infestations is slower so that they are less frequent but last for considerably longer periods. In both areas the existing mature timber supply has a high proportion of lodgepole pine. The threat from mountain pine beetle is substantial in both timber supply areas.

    Assessments of the short-term impacts of the mountain pine beetle on the timber supply focussed on a timeframe of 50-100 years. Assessments of the long-term impacts of the mountain pine beetle on the timber supply focussed on a timeframe of 400-600 years.
