The FlamMap analysis wasconducted using the same weather, fuels and canopy data as the SanbornWFSI.In comparison to the wildfi re susceptibility layer, this data layer reveals nearly5.7 million acres with a high to very high wildfi re intensity ranking. Spruce-fi rforests, which naturally burn in infrequent stand-replacing fi res, account formore than 2 million of these acres, followed by mixed conifer and ponderosapine forests. The USFS manages the majority of these forests in which 3.7million acres are in the high and very high categories. Private lands accountfor another 1.2 million acres in these categories; the BLM oversees justunder 500,000 acres that also are ranked in these categories. Managementin landscapes ranked high to very high could help reduce the potential forhigh-intensity crown fi re where such fi re is unwanted, or ensure that valuesat risk are proactively protected in areas where such fi re may be desired fornatural resource benefi t.27For more information on FlamMap, please see www.firemodels.org.29
