Peat swamp forests are one of the most important peatland ecosystems because these ecosystems consist of the carbon-water complex, which is affected by the impact of human and climate change. Peat swamp forests form in areas where saturated soils or frequent flooding prevent organic material from fully decomposing. When a forest is cut down, the loss of above-ground carbon is obvious. However, less obvious is that 90 percent of a peat swamp forest’s carbon is stored below ground. As the accumulation of so much organic material means tropical peat swamp forests store a lot of carbon: up to 10 to 20 times more carbon than nearby lowland forests on mineral soil that depends of the depth of soil and age of forest. Indonesia contains 47% of the global area of tropical peatland (Page et al., 2011) mostly as extensive domes of woody peat, supporting peat-swamp forests that covers vast areas of lowland landscape between major rivers.
Mycorrhizal fungi associated with plant roots increase the absorption of nutrients, particularly phosphorus, and thus enhance the growth of trees. By this reason, the technology to use mycorrhizal fungi is a noval and effective method in reforestation. The mycorrhizal fungi for inoculation including AMF (Gigaspora sp., Entrophospora sp., and Acaulospora sp.) and ECM (Chantharellus sp., Boletus sp., Amanita sp., and Scleroderma sinamariense). The species of tree seedings we used are Melaleuca leucadendron, Combretocarpus rotundatus, Dyera polyphylla, Shorea balangeran and Alstonia pneumatophora. Besides, we make the seedings containers by organic material, such as bamboo, purun and rumbia, which are biodegradable without pollution.
In addition, we have set up the carbon sink measurement in the revegetation area. We are measuring the carbon sink in every year in order to find out the positive effect of the reforestation process in carbon sequestration.
