Abstract

The study in the Southeast Asia regarding fisheries, tourism, including aesthetic value estimated the sustainable economic benefits per km² of healthy coral reef ranging from US$23,100 to 270,000. The question is how this goes for limited area consisted of mangrove-sea grass-coral reef, which found in many coasts throughout Indonesia archipelago. Should it be ignored? The purpose of the study was to indicate the existing economic values of limited coastal area consisted of mangrove, sea grass be, and coral reefs of the Ringgung coast of Pesawaran, Lampung Province. The results indicated that from coast length of 2.4 km, the total area of the wetland is approximately 78 ha consisted of 4.75 ha of mangrove, 22 ha of sea grass bed, and more than 50 ha of coral reefs. The economics values of the area study were predominantly used for grouper farms, with more than 15 individual farms, recreation, and Rizhopora culture (for seedlings) operated by locals. The economic values of the Ringgung coast by using direct use value of the grouper farms indicated that the yearly fish productivity was grossly of US$ 640,985. This number could be added up by the other economic values, such as recreation and saling of Rizhopora seedling. We can conclude that this economic values provided by the coastal ecosystem should be made to conserve the existing ecosystem. Besides, in order to maintain sustainable economic of the ecosystem, some consideration should be made in regard of carrying capacity for grouper farms in the area study.

Abstract

Studies of nutrient cycling of tropical forests should differentiate between dynamic stages of the forest. We studied the nutrient concentration (N, P, K, Ca and Mg) and phytomass of aboveground (living and non living parts) and belowground compartments (soil) in four dynamic stages, namely Building (Bl and B2), and Mature (Ml and M2) stages, for a lowland rain forest. Nutrient concentrations in various compartments differed between the dynamic stages. Bark contains higher nutrient concentration than wood parts, both in stems and branches. Leaves contain higher nutrient concentration than wood parts, both in litterfall and litter. The concentration of K in throughfall is the highest, Ca and Mg perform similar value. Throughfall exhibits lower nutrient concentration than open area rain water. The nutrient concentration of 10-20 cm is higher than in the 0-10 cm soil depth. The phytomass values are highly variable among tree parts, diameter classes and dynamic stages. The phytomass is generally the highest in M2 and significantly different from Bl ,  Ml and B2. The phytomass of leaves in litterfall and litter is higher  than wood parts. More litterfall and litter are accumulated in mature than building phases. Key words : nutrient / phytomass / dynamics / rain / forest
