3. 1. INTRODUCTION Many peat swamp forests have been converted to plantation, agriculture, resettlement etc. Three important principles of successful management of ecosystem: 1. There is a limit to the intensity, size, and duration of disturbance which an ecosystem can resist and still maintain its productivity and ability to recover 2. Native species are often most effective at maintaining the productive capacity of a site or of restoring soil fertility. 3.Nutrient cycling is very important to sustain the ecosystem.

5. 3. Result of nutrient dynamic studies Nutrient budget: MSF: Ca:7.5; Mg:3.2; Na:0.7 kg/ha/yr. LPF: Ca: 8.6; Mg:3.5; Na:0.7 kg/ha/yr

6. Implications of nutrient dynamics studies for conservation and management of peat swamp forest 4. Implications of nutrient dynamic studies Based on the results of nutrient studies in tropical peat swamp forest it is evident that there is nutrient surplus in the natural ecosystem, because of it is possible to harvest timber over certain time periods. A database for forest management based on nutrient content of vegetation components. 5. Future research related to management Carry out research on nutrient content of individual tree species, especially commercial species such as ramin ( Gonystylus bancanus) to estimate the number of trees that can be harvested sustainable during a certain period of time. Compare the management practices and economic values of sector activities on tropical peatland - Agriculture, Plantation and Forest
