Description:
The BC Rocky Mountain Trench (RMT) has an estimated 250,000 hectares departed from historical fire regimes consisting of heavy fuel loads needing thinning and prescribed burning (RMT ER Steering Comm. 2006). Thousands of hectares are in the wildland urban interface (WUI), generally described as a 2 km buffer zone around municipalities, and pose significant wildfire risk (Filmon 2004). Several municipal initiatives within the RMT region have begun fuels treatments on high risk stands. Causes and effects of the departure from historical fire regimes due to silvicultural practices and fire suppression in BC have been researched (Filmon 2004, Forest Practices Board [FPB] 2006). Initiatives such as the development of Fire Safe Councils in the US and the Fire Smart program and WUI funding in BC have begun to address WUI fuels problems. Many reports and initiatives identify the need for commercial opportunities to economically handle forest biomass to reduce wildfire risk (USDA 2003a, USDA 2003b). The US has documented the billions of dollars of wildfire costs (above suppression costs) in terms of lost timber values, environmental restoration, socio-economic costs and property values (USDA 2005) and BC has experienced similar losses, as documented from the 2003 fire season (Filmon 2004). Silvicultural treatments, followed with prescribed burning are needed to minimize wildfire risk within WUI timber stands (Gray 2005). New guidelines are needed to assess these stands to incorporate fuels treatments into forest management plans. Responses by the Ministry of Forest and Range (MOFR) Protection Branch are addressing the recommendations of the Filmon (2004) report, however implementation is challenging. The MOFR and municipalities have begun treating WUI fuels within the region; however, the scale of treatments needs to be seriously increased to be effective. An increased risk of catastrophic wildfires in the RMT is probable if the scale of fuels treatments is not increased (Taylor et.al. 1998). Problems facing fuels reduction efforts in the WUI include: lack of stand data to accurately model wildfire risk under current stand conditions; lack of integration between crown lands, First Nations reserves and private land owners, making strategies difficult to implement on a landscape level; and challenges to implement fuels reduction via prescribed burning due to smoke related issues. Lack of training by forest managers and registered professional foresters (RPFs) of the available tools and methods to assess wildfire risks has been a barrier to implementing fuels treatments and to meet stand restoration/forest health objectives (FPB 2006). There has also been a lack of knowledge about adequate tools and methods for making economic decisions related to prioritizing stand treatments for fuels removal in BC. This project will assess fuels risk on 760 hectares near Cranbrook using current fuels assessment tools such as Fire Management Analyst Plus® (Carlton 2005) and determine the economic costs for fuels treatments using Landscape Management System (LMS) software (Rural Tech Inst 2006). These assessments will be used to determine wildfire risk under various stand treatments and integrate economic analyses for treatments on a stand/polygon basis. Best practices will be developed for planning and implementing fuels treatments resulting in a guidebook for forest managers, First Nations, and city planners. This project will evaluate the current stumpage appraisal system to determine what revisions may make WUI treatment economical for licensees and First Nations. Companies across BC, Canada and the US are utilizing forest biomass for biofuels/energy, and pellets (BioCap 2006). The results of analyses evaluating the benefits and trade off of silvicultural treatments of timber and biomass production within a fuels reduction context have not been effectively integrated into forest management planning. Using current stumpage methods, attempts to utilize biomass from fuels treatments have faced economic challenges as negative stumpage from fuels treatments have been a limiting factor (Dureski 2005, Blissett 2006). The evaluation follows recommendations made by the FPB (2005) and Filmon report (2004) which state that amendments to current tenures and stumpage calculation methods are needed to encourage the proper treatments of high risk WUI stands and create incentives for industry and First Nations’ participation. Low value timber stands in the WUI are not a priority for licensees as fuels treatments are not economical and incentives for industry to co-operate in fuels reduction programs are lacking. This project will recommend reasonable methods in which to assess fair stumpage. An evaluation of current tenures will also be conducted and recommendations made for modifying the current system enabling more flexibility that allows forest companies with tenures to maintain their AAC and not penalize tenure holders who participate in WUI fuels treatment projects. The threat of wildfire risk poses millions of dollars of potential losses within the WUI, affecting timber production, ecosystem health, and personal property. The development of guidelines using proper tools for wildfire risk assessment and implementation, and an evaluation and recommendations for stumpage and tenure policy changes which create the proper incentives for implementing fuels treatments, is critical to BC forest management and has the potential to save the BC government, First Nations and private land owners millions of dollars. This project provides an excellent opportunity to engage local communities and stakeholders in discussions about wildfire risk and build capacity within these communities that leads to successful wildfire risk reduction in the WUI.
