Tropical peatland is an important ecosystem of the world. The degraded peatlands are usually caused by anthropogenic distractions. Drained peatlands are necessary to be restored by rewetting and replanting with native peatland plant species, which provide both ecology and economic benefits. Peatland rehabilitation with paludiculture is implemented in a peat forest area in the peatland hydrological unit of Katingan and Mentaya rivers, under a framework of research collaboration between National Research and Innovation Agency (BRIN) and a private company of Rimba Makmur Utama. Four plant species have been planted in a two-hectare demonstration plot, namely Shorea balangeran, Dyera polyphylla, Notophoebe coreaceae and Metroxylon sago. The growth of four plant species is being monitored up to 2 years after planting. This activity shows the significance of collaboration between the private sector with a research institution, to support the country in achieving sustainable development goals of climate action (SDG 13) and life on land (SDG 15).
