From the text...'Major forest types include those where aspen, eastern white and red pine stands, and jack pine stands are found either as fire-maintained seral types or exceptionally as climax stands (see table 3-1 for FRES, Kuchler, and SAF cover type designations). This includes extensive areas from Newfoundland across to Alaska and the Great Lakes region. Fire regime characteristics varied extensively for these major vegetation types, reflecting local and regional topography, fuel type and climate. Fire regime characteristics (summarized in table 3-1) are discussed by first describing distribution and site features of the major vegetation types followed by discussion of the nature of fire.'
