Abstract

The main objective of the Isobel dry-belt fir management project is to develop and apply prescriptions to maintain prolonged open canopy conditions in dry Douglas-fir (IDFxh2) forests. Much of the current emphasis in ecosystem restoration in these forest types has focused on the use of prescribed fire to achieve desired conditions, with few prescriptions being developed in the Kamloops Forest Region using a combination of harvesting and silviculture to achieve prolonged open conditions while maintaining long-term opportunities for timber extraction. A complete and extensive assessment of pre-harvest conditions at 180 permanent sample plots was completed in 2002. The harvesting component of the operational trials has been a success with 50-80% of the basal area removed at the trial site in a manner consistent with treatment objectives. Evaluating post-harvest conditions along with site preparation and livestock management are the main objectives in 2003-04.
