Fire management in Canada's national parks is facing other alternatives besides traditional suppression. The 1979 Parks Canada Policy permits a full range of options while the Natural Resources Management Process (NRMP) provides the framework by which specific options will be determined and approved. Banff National Park's lower Bow Valley contains a high capital development, a high visitation number, and a fire-prone vegetation. This provides a setting for a simulated fire program where the negative exponential distribution of fire intervals is reinstated through the use of randomly scheduled planned ignitions. Potential constraints to the realization of such a program vary from public and internal perceptions of such a program to the ability of matching the natural fire intensities in certain sensitive areas of the park. A vegetation plan approved through the NRMP is a key to fire management in national parks. Such a plan must initially be formulated on sound ecological principles and then modified in accordance to management requirements and constraints.
