Table 3 Basal area (m2 ha−1) for all stems 3.8 cm dbh and greater under three thinning (0 = no thinning, light = residual basal area 17.2 m2 ha−1, and heavy = residual basal area 11.5 m2 ha−1) and three prescribed burning regimes (0Rx = no fire, 1Rx = 1 fire in 7 years, 3Rx = 3 fires in 7 years) on the William B. Bankhead National Forest, Alabama, USA. Time 0 reflects pre-treatment, Time 1 is post thin and post first burn, Time 2 is post second burn, Time 3 is post third burn. Different letters within a column indicate significant difference at α < 0.05.
