Fire cycles and forest management: An alternative approach for management of the Canadian boreal forest.

Forest managers in Canada urgently require solutions for achieving the goals of sustainable development and the conservation of biodiversity. To attain these goals, many have suggested the use of landscape pattern resulting from naturally occurring disturbances as a template for forest management. Forest fires constitute one of the main disturbances affecting forest dynamics in the boreal. Fire cycle studies have revealed the high variability of this parameter from one region of boreal forest to the next. Fire cycle is often used as a forest management tool, but since it is highly variable in time and space, using the mean time since fire seems to be a simpler and more realistic approach.

Published literature was used to determine both fire cycle and mean time since last fire of forests across the Canadian boreal forest. Based on the mean time since fire of the stands, the percentage of forest which could be managed to reproduce the fire controlled age structure conditions found for each Canadian region studied was determined. This report provides forest managers with a tool that can be used to help achieve sustainable forest management and the conservation of biodiversity.
