Table 1 Tree density and basal area in 8 yr old, 28 yr old, and 60 yr old stands of Pinus douglasiana following high-severity fires in central-western Mexico. Values represent averages for each stand, with standard error in parentheses; a and b show significant differences between means (P < 0.05) with the post-hoc Tukey test.
