Litterfall in Toh-Daeng primary peat swamp forest at Narathiwat Province was measured monthly from June 1991 to May 1994. The element concentrations in the litterfall (N, P, K, Ca, Mg) were determined. Litterfall was measured in sixteen 1*1 m traps. The mean total litterfall over a period of three years was 6.7 tons/ha/year. Leaf, wood, reproductive materials, and unclassified litter were 4.1, 1.4, 0.4 and 0.8 tons/ha/year, respectively. Nutrient content of litterfall were 53.7, 3.1, 71.2, 71.7, and 13.9 kg/ha/year for N, P, K, Ca, and Mg, respectively. Leaf litter peaked from early to mid rainy season and was lowest during the highest rainfall month.
