Q. Is VCC the same as FRCC?
Vegetation Condition Class (VCC) and Vegetation Departure (VDep) are the same data that was previously called Fire Regime Condition Class (FRCC) and Fire Regime Departure Index (DEP). According to the FRCC Guidebook, FRCC was an interagency tool used to determine the degree of ecological departure from historical, or reference condition, vegetation, fuels, and disturbance regimes. FRCC, a combination of vegetation departure, fire frequency, and severity departure, were measures of vegetation departure, hence the name change.
