Forest Age Structure

The dominant management strategy in boreal forests—aggregated clearcuts (AC)—faces increased criticism by various stakeholders, including Aboriginal people. Two alternative strategies have been proposed: dispersed clearcuts (DC) and ecosystem-based management (EM). We modelled the long-term and landscape-scale effects of AC, DC, and EM on a set of indicators of sustainable forest management relevant to an Aboriginal community's values: (1) forest age structure; (2) spatial configuration of forest stands; (3) road network density; and, (4) forest habitat loss to clearcuts. EM created a forest age structure closer to what would result from a natural disturbance regime, compared to AC and DC. Cut blocks were more evenly distributed with EM and DC. The road network density was lower and increased slower with EM, thus reducing the potential for conflicts between forest users. Under EM, a higher forest cover was maintained (and thus potential wildlife habitat) than in AC or DC. The EM scenario provided the best outcome based on the four measured indicators, partly because the constraints imposed on the modeling exercise led it to harvest less than the other scenarios. Annual allowable cut should thus be a key factor to consider to ensuring better compliance with Aboriginal criteria of sustainable forest management.

Forest Age Structure

The effects on timber supply incurred by implementing an ecosystem-based management strategy were evaluated in an eastern Canadian boreal forest management unit. Standard linear programming was used to test the effects of four key policy issues: (1) aim for a targeted forest age structure inspired by natural fire regime and forest dynamics (multi-cohort approach), (2) agglomerate harvest blocks in operating areas to reproduce natural disturbance patterns at the landscape scale, (3) maintain cumulated clearcutting and natural disturbance rates inside the historical range of variability, and (4) exclude from harvest areas of potential interest to aboriginal people. The targeted forest age structure was achieved with a minimum reduction of periodic timber supply, but only after 50 years. Compared to a “business-as-usual” scenario, inclusion of the first three policy issues resulted in a 3% to 11% reduction in planned timber supply and a restoration period requiring that 43% to 67% of the productive area be excluded from clearcutting activities for the next 50 years. Such results require that partial cutting not be confined to operating areas eligible for clearcutting. Further exclusion of forest areas of potential interest to aboriginal people resulted in an additional 4% to 10% decrease in planned timber supply. Validation of the coarse filters used in this study (first three policy issues) was done using habitat requirements of woodland caribou (Rangifer tarandus caribou). Almost all scenarios induced a disturbance rate likely to allow a self-sustaining woodland caribou population within 25 years.
