The accelerated level of harvesting in a concentrated time frame in Mountain Pine Beetle (MPB) affected forests requires a strategic plan for the retention of non-pine species to provide certainty for mid-term timber supply and diversity of habitats across the landscape. To meet this need, strategic level guidance for harvesting priority and silvicultural practices are required to reduce the impacts of MPB management on future timber supply and other values. The Chief Forester, Jim Snetsinger, has requested that Craig DeLong and Dave Coates co-ordinate the testing of different harvesting strategies using landscape (SELES, FSSIM, VDYP) and stand-scale (SORTIE-ND, TASS) models.

The objectives of this project are to:

1. Compile a list of stand structural types found in MPB damaged stands.

2. Model results of alternative salvage and rehabilitation strategies, with an emphasis on implications for mid-term timber supply.

3. Model results of alternative salvage and rehabilitation strategies, with an emphasis on implications for wildlife habitat values.
