The map of dominate vegetation types in the Region was last updated in 2009. Since then only the Angora fire burn area has been updated. In 2009, satellite imagery, aerial photographs and field reconnaissance (USFS Forest Inventory and Analysis data) were used to delineate and classify vegetation types in the Lake Tahoe Region. This information is digitized into a geographic information system and subsequently analysed to summarize vegetation community richness. Information from the Tahoe Fire and Fuels Team (a multi-agency partnership) on forest fuels treatments and disturbance events are incorporated for year to year change in vegetative composition.
