Carbon dioxide emission on burnt peat swamp forest in Raja Musa Forest Reserve, Selangor

Peatlands area was known as one of the largest carbon pools. However, burnt in peatlands area caused emission of carbon dioxide which leads to global warming. Environmental factors such as soil temperature and soil humidity affect the carbon dioxide emission. This study was carried out to investigate the trend of carbon dioxide emission on burnt peat swamp, located at Raja Musa Forest Reserve. This area had experienced forest fire since 1996. Soil CO2 emission was measured using Li-COR 8100 Automated Soil CO2 Flux System. Based on the measurements, emission rates were ranged from 2.13 to 8.50 μmol m-2 s-1 for three months from August until October. Correlation analysis between soil CO2 emission with environmental factors showed that soil CO2 emission was significantly correlated with soil temperature, soil humidity and peat water level. This study shows that environmental factors significantly affect the increased in soil CO2 emission.
