The different fire regimes present in the province of British Columbia are well-illustrated by the Coastal Western Hemlock, Boreal White and Black Spruce, and Ponderosa Pine Biogeoclimatic Zones. Fires are variable in type, intensity, severity, effects, size, and interval. In the first two biogeoclimatic zones, stand replacement and/or partial stand replacement fires occur. Surface fires that maintain open forests with grassy understories are the historic norm in the Ponderosa Pine Zone. Fire histories and fire effects have been determined for all three zones. In the Coastal Western Hemlock Zone the emphasis has been on fire history, stand establishment, and prescribed burning. Ecosystem-specific guides describing the type of fire suitable for silvicultural site preparation are widely available. Post-fire vegetation successional pathways have been developed for the Boreal White and Black Spruce Zone and are used to predict probable fire outcomes. In recent times, the adverse implications of fire exclusion have been recognized in ecosystems such as those found in the Ponderosa Pine Zone. The reintroduction of fire through prescribed burning serves to address the problems and meet several resource management objectives.
