Based on Indonesian Minister of Environment and Forestry Decree number SK.30/MENLHK/SETJEN/PKL.0/2/2017 concerning in determination of national peat ecosystem function map, Indonesia has 865 peat hydrological units with the total area is 24,667,804 Ha which can be divided into peat ecosystem protection function (12.398.482 Ha) and peat ecosystem cultivation function (12.268.321 Ha) (Figure 3). The detailed data of peat ecosystem function area in each province are shown in Table 2.
