Table 2 Descriptive analysis of diameter at breast height (DBH), crown injury percent (CI), and years to death post fire (YTD) by species and status. Species codes are: IC = incense-cedar; SP = sugar pine; WF = white fir; and YP = yellow pine. Status of 0 is standing and status of 1 is fallen at year 10. P-values are for Wilcoxon signed rank tests. SE = standard error
