|The lack of knowledge regarding the growth response of subalpine fir (Abies lasiocarpa) to incremental silviculture treatments was the catalyst for establishing the Blunt Fire Incremental Silviculture Project. The most recent Timber Supply Review for the Bulkley TSA (April, 2001) has projected a 37 percent decline in harvestable volume within the next twenty years. The Bulkley TSA Type 1 Silviculture Strategy (March 2000) has identified mitigation of the projected reduction in harvest levels as a key TSA issue and the application of incremental silviculture techniques has been identified as a key tactical priority. As subalpine fir occupies approximately 48% of the timber harvesting land base, expanding the knowledge regarding the response of subalpine fir to incremental silviculture treatments will provide useful information on the opportunities for their use in mitigating timber harvesting reductions. The Blunt Fire project area is located 65 kilometres north of Smithers at an elevation of 1000 metres. The 950 hectare project area is comprised of a naturally regenerated subalpine fir stand with a minor spruce component. Stand initiation occurred in the 1930ís following a wildfire. This project was established in 1996 through funding provided by Forest Renewal BC. Preliminary reconnaissance through pre-stand tending surveys and the preparation of Stand Management Prescriptions identified the project area in 1996. Permanent Sample Plots were established in 1997 to record pre and post treatment stand and site conditions. Re-measurement of the permanent sample plots occurred in the spring of 2001, three years after initial treatment and now in the fall of 2006, eight years after initial treatment.|
