Abstract
Litter production, nutrient concentration of each component of litterfall and amount of nutrients input to forest floor via litterfall were investigated for three years from May 2005 through April 2008 in Pinus densiflora forest at Mt. Worak National Park. Amount of litterfall in 2005, 2006, 2007 were 3.070, 3.066, 3.099 ton ha-1 yr-1, respectively. Average amount of litterfall for three years was 3.078±0.018 ton ha-1 yr-1. Average percentage of leaf litter, branch and bark, reproductive organ and the miscellaneous for three years were 61.9, 10.4, 5.2, 22.5%, respectively. Average amount of N, P, K, Ca and Mg returned to forest floor via litterfall for three years in this P. densiflora forest were 18.014, 0.878, 4.240, 7.349 and 2.172 kg ha-1 yr-1, respectively.
