To assess the current state of wildland fire as an ecological process in the interior forests (Pukaskwa Plains, Bremner Uplands and Bremner-Widgeon Uplands ecodistricts) of Pukaskwa, the Area Burned Condition Class (ABCC) measure calculates the modern-day departure from historical wildland fire cycles (i.e., fire frequency). Area burned (hectares) and fire locations from wildland and prescribed burns are collected annually. Calculations of the ABCC follow the methods outlined in the Park Canada Agency’s Fire Monitoring Guide.
