In 2000 the Squamish Forest District began a pilot project to study the effects of prescribed fire on forest succession, fuel dynamics, regeneration, wildlife habitat, and timber supply within two landscape units encompassing 103,000 ha north of Pemberton, British Columbia. These landscapes have been negatively affected by fire suppression during the previous 100 years. In the absence of fire, the structure and function of many ecosystems within the study area have been altered. This has resulted in deterioration of forest health, increased fuel loadings and resulting fire hazard, and negative impacts on available wildlife habitat. The first objective of the pilot project is to use the Wildfire Threat Rating System (WTRS), a Geographic Information System (GIS)-based model, to spatially identify those areas that 1) pose a significant fire threat, 2) have been significantly impacted by the effects of fire suppression, and 3) have the highest risk of loss or damage from wildfire effects. The second objective of the project is to develop mechanical and prescribed fire treatment strategies designed to restore ecosystem structure and function and to ameliorate suppression impacts on forest succession, forest health, fuels, and wildlife habitat. We document the results of the WTRS and identify candidate treatments and treatment areas where ecosystem restoration can be targeted. © 2004, Tall Timbers Research, Inc.
