We used a simulation model and two management scenarios to investigate possible effects of a severe mountain pine beetle (Dendroctonus ponderosae Hopkins) epidemic in Alberta, Canada. Our simulated outbreak was based on the current epidemic in British Columbia, which may kill close to 80% of the province's pine volume. Our two management scenarios were conventional harvest and a pine-reduction strategy modeled on a component of Alberta's Mountain Pine Beetle Management Strategy. The pine strategy seeks to reduce the number of susceptible pine stands by 75% over the next 20 years through targeted harvesting by the forest industry. Our simulations showed that the pine strategy could not be effectively implemented, even if the beetle outbreak was delayed for 20 years. Even though we increased mill capacity by 20% and directed all harvesting to high volume pine stands during the pine strategy's surge cut, the amount of highly susceptible pine was reduced by only 43%. Additional pine volume remained within mixed stands that were not targeted by the pine strategy. When the outbreak occurred in each scenario, sufficient pine remained on the landscape for the beetle to cause the timber supply to collapse. Alternative management approaches and avenues for future research are discussed.

The S2Mountain Pine Beetle Symposium: Challenges and SolutionsS3 was held in Kelowna, British Columbia, Canada on October 30-31, 2003. This meeting was organized by Natural Resources Canada, Canadian Forest Service, Pacific Forestry Centre and funded through the Government of Canada Mountain Pine Beetle Initiative. Approximately 250 people representing the forest industry, consultants, universities, provincial and federal government agencies, First Nations, and the general public, from both Canada and the United States attended the meeting. Thirty presentations were given describing the current mountain pine beetle situation (in British Columbia, Alberta and the western United States) and its management and economic implications. Researchers presented the latest information on remote sensing, decision support systems, impacts on stand dynamics and wildlife, phytosanitary risks, climate change effects and preventive management as they relate to mountain pine beetle.
