Abstract:
Three plantations of longleaf pine (Pinus palustris Mill) in South Carolina, 7, 11, and 13, years old, produced 298, 1,669, and 2,525 kcal/m² per year of litter, respectively. The total standing crop of tree material was 3,171, 17,795, and 43,277 kcal/m², respectively. The 7—year—old stand had the lowest density of trees and had not achieved a closed canopy. Annual needle fall average 57% of the spring standing crop of living needles. During the 7— to 13—year period the rate of net biomass accumulation per tree did not decrease, although the production of leaves to woody tissue decreased from 32% to 10%. The production characteristics of P. palustris differ markedly from those of a Virginia pine (P. virginiana) stand from the southeastern coastal plain of the United States.
