Project Proposal

Due to the overwhelming magnitude of the mountain pine beetle epidemic, management emphasis has shifted from efforts to control the epidemic to efforts to mitigate its impact on communities and the environment. The Allowable Annual Cut has been increased in most management units which may lead to a fall-down in timber supply in the medium to long term. It is likely that significant areas of infested forest will never be salvaged due to the large area that is impacted. Forest managers must now make decisions about which stands should be salvaged, which should be left to regenerate naturally, and which stands may require rehabilitation.

The overall objectives of this project are to:

1. Quantify tree seedling recruitment across the full range of stand types affected by MPB in the northern interior. Two critical factors affecting recruitment success will be assessed: abundance of parent trees and seedbed substrate favourability.

2. Develop, test and parameterize non-spatial recruitment models for MPB damaged forests that can be incorporated into stand and landscape dynamics models.

3. Determine the relative importance of long-distance versus local dispersal.
