Communities throughout British Columbia are vulnerable to forest fires. At particular risk is the Wildland-Urban Interface (WUI) zone. Recent interface fires in British Columbia and in other jurisdictions have provided evidence that completed fuel-reduction treatments reduce fire suppression costs, improve safety for residents and firefighters, and improve the resilience of forests subjected to fire (Safford et al. 2009, Rogers et al. 2008). However, the cost of such treatments has been high and the rate of treatments slow.
In this report we provide Best Management Practices (BMP) guidance for harvesting and thinning activities in the Wildland stands within Community Wildfire Protection Plans. The report considers areas of the Interior Douglas-Fir (IDF) biogeoclimatic zone within Williams Lake Timber Supply Area. Fuel and fire behaviour modelling, an extensive literature review, and operational experiences have been synthesized to provide guidance for fuel management. It focusses on achieving land use objectives while:
Reducing crown closure;
Maintaining low surface fuel loading; and
Increasing canopy base height.
We suggest that fuel treatment rates can be increased and costs lowered if licensees undertaking harvesting and thinning treatments can be induced to modify fuels in conjunction with their other objectives. We further believe that the intensity of the fuel treatment should vary according to the proximity to values at risk.
