Abstract
CO2 emissions were studied on tropical peat swamp forests PSF on one large peat covered catchment - the Sungai Sebangau catchment in Central Kalimantan and two developed sites which have formerly been peat swamp forests PSF. An infrared gas analyzer was used for in situ determination of CO2 emissions on c. 20 cm diameter study plots cleared from green vegetation. The most extreme CO2 emissions in pristine PSF sites were 276 and 682 mg mE-2 hE-1 which were found at WT levels of 20 cm and -35 cm. At most WT levels during the measurement CO2 emission rates were equal to or bigger than 600 mg mE-2 hE-1. In developed sites CO2 emission rates varied between 216 and 404 mg mE-2 hE-1 while the average emission rate was a bit over 300 mg mE-2 hE-1. On average CO2 emissions were almost twice as high in pristine forest types as in developed sites if compared the same water table levels. The differences in CO2 emissions between pristine and developed PSF may be compared to the differences of a healthy respiring organ and a dead decomposing one.
