Abstract

The objectives of the present study were to determine the quantitative characteristics of mangrove forest in the Prednai community, Trat province, including the important value index, biomass and litter production. The results showed that mangrove forest consisted of 10 species with a diversity index of 0.56. Ceriops tagal showed the highest important value index of 86.55. The average tree density was 2,977.78 trees/ha, while the densities of saplings and seedlings were 7,222.22 and 8,333.33 trees/ha, respectively. The average total height and diameter at breast height of trees in this forest were 7.40 m and 9.31 cm, respectively. The total aboveground biomass of trees was 113.70 ton/ha with the litterfall production of 8.75 ton/ha/yr. The highest litterfall was found in November. Calcium showed the highest concentration in litter while phosphorus showed the lowest concentration. The nutrients lost from litterfall were equivalent to 2.09, 0.87, 0.79, 0.45, and 0.09 t/ha/yr for calcium, nitrogen, magnesium, potassium and phosphorus, respectively.
