Litterfall Patterns in Mature Loblolly and Longleaf Pine Stands in Coastal South Carolina
Abstract:Seasonal patterns and quantities of litterfall were measured in two-storied stands of loblolly pine (Pinus taeda L.) and longleaf pine (P. palustris Mill.) in coastal South Carolina for 4 years. Seasonal patterns of litterfall of both stands were similar with high rates in both spring and fall and definite periods of low litterfall rates during late summer and mid to late winter. Total annual litterfall averaged 7,799 kg ha-1 yr-1 in the loblolly stand and 4,884 kg ha-1 yr-1 in the longleaf stand. In both stands, foliage from the overstory pines and understory species accounted for about three-quarters of litterfall and small branches, bark, cones, and catkins accounted for the remainder. In the loblolly stand, the foliage component of litterfall consisted of mostly loblolly pine fascicles (81 percent) and leaves from several understory species. Only 57 percent of the foliage litterfall in the longleaf pine stand was longleaf fascicles. Forest Sci. 28:223-231.
