Table 5 Intra-ring position of DRY plot fire scars in dry years (PDSI < 0) and wet years (PDSI > 0) for the period 1700 to 1850 and the period 1851 to 1900. PDSI was normalized with a mean of 0 and a standard deviation of 1 for the analysis years (1700 to 1900). Values shown are percent for each period (number of scars) in each intra-ring position.
