Fast-Grown, Dense Loblolly Pine Sawlogs: A Reality
Loblolly pine sawtimber with a mean d.b.h. of 15 inches was produced in 27 years through heavy thinning, understory control, and green pruning. Three levels of intensive culture were compared with conventional practice (moderate thinning, no pruning, no understory control). At age 27, standing volume was 11.9 M b.f. per acre in intensive treatments and only 5.3 M b.f. in controls. Mean d.b.h. was 14 to 15 inches under intensive culture and 10 inches in control stands. Control stands produced greater cubic yields than intensively managed stands. Unextracted specific gravity of trees harvested at age 27 was unaffected by treatment and was approximately equal to local average for loblolly pine.
