The landscape and stand-level fire history of lodgepole pine dominated forest in Tenderfoot Creek Experimental Forest is assessed. Primary objective were to: 1) determine pre-1900 fire periodicities, severities, and burning patterns in the area's lodgepole pine dominated stands, and 2) document and map the forest age class mosaic, reflecting stand replacing fire history at the landscape level of analysis. Secondary objectives were to interpret the possible effects of long-term fire suppression on area forests, and to determine their relative position along the fire regimes continuum for northern Rockies lodgepole pine.
