Yellow poplar had a basal area of 8.5 m2/ha in the
even-age management with intensive harvesting (EA-I)
compartment and had successively lower basal area
along our hypothesized disturbance gradient, with EA-I
followed by even-age management with extensive harvesting
(EA-E), even-age management with commercial
harvesting (EA-C), diameter limit harvesting (DL), and
a minimum basal area of 2.4 m2/ha for single-tree
harvesting (ST). Sugar maple exhibited the oppositepattern, with minimum basal area of 1.2 m2/ha for EA-I
and maximum basal area of 10.0 m2/ha for ST (Figure
3).
