Description

This paper looks first at the kind of forest fire statistics that are currently available in Canada. The main statistics are number of fires area burned, causes, and control costs. Good inventory data on burned areas are not available. The recent rising trend in national burned area is then presented, with its uncertain implications for the future. Next follows a comparison of two methods of portraying the impact of fire on Umber supplies: (1) by a static accrual-depletion balance; and (2) by dynamic analysis of the interaction between harvesting and fire in a managed forest. These two approaches do not give the same result. The conclusion is drawn that modern dynamic analysis is necessary to clarify the impact of fire, and that the answer will be found in the timber output from the whole forest, not in the killed timber on the burned area. Some examples of simple dynamic simulation are presented, with implications for the optimum management strategy in a fire-prone forest.
