A multi-proxy palaeoecological investigation including pollen and spore, loss-on-ignition, total organic carbon, stable carbon isotope and micro- and macrocharcoal was carried out on two peat cores collected from coastal area in southern Borneo. The study was conducted to understand the development and dynamics of the coastal peatlands, the Katingan in Borneo. Microcharcoal analysis was conducted following point count method (Clark, 1982) and counted on the same slides for pollen and spore analysis.
