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
