              This assessment is not based on any assumptions regarding prescribed burning with temporary hazard
              reduction benefits; and has to be based on fuel levels reaching a long term maximum stable state, coinciding
              with ignition under worst case foreseeable fire weather conditions.

              4.1        Fire History and Frequency

              This study found no evidence of fire in the area. Occurrence of fire is anticipated, potentially coinciding with
              full potential fuel accumulation and worst case fire weather conditions.
