Rehabilitation of Understocked Loblolly-Shortleaf Pine Stands—I. Recently Cutover Natural Stands [PDF]

open access: yesSouthern Journal of Applied Forestry, 1998
Abstract Two loblolly-shortleaf pine (Pinus taeda L.-P. echinata Mill.) stands were cut to stocking levels of 10, 20, 30, 40, and 50% to simulate recently cutover, understocked, uneven-aged stands. Number of trees ranged from 38 per acre for 10% stocking to 213 per acre for 50% stocking; comparable total basal areas were 4 and 16 ft²/ac,
