(orange) and survival (green) percentages for 13 stands, corrected for ongoing background mortality
(self thinning) as observed in unburned stands. Error bars are 95% confidence intervals for duplicate
Control and Late, lo-wood stands.
Douglas-fir saplings in young 5-yr-old
stands (both Pioneer and Douglas-fir treatments) were all killed either by the wildfire or the backburn set to fight the fire.
The Late-succession, thinned and underburned stand had the lowest Douglas-fir mortality (36%) of all the wildfire-burned stands.
The two Control stands had significantly lower mortality (70%) than the two thinned, Late-succession, lo-wood stands (92%); and lower than the one thinned, Late-succession, hi-wood stand (100%).
