“…As a whole, the The delineation of peatland areas in this study was based on existing peatland maps (Wahyunto et al 2003(Wahyunto et al , 2004. Although these maps are the newest and most reliable maps that are currently available, it has been suggested that they may underestimate the extent of peatland areas for as much as 10% (Jaenicke et al 2008). In addition, 17% of the peatland areas could not be mapped due to the lack of cloud-free data.…”

“…Although it has been suggested that the abovementioned peatland distribution maps may underestimate the extent of peatlands for as much as 10% (Jaenicke et al 2008), no corrections or modifications to these maps were attempted in this study. This was considered to be the best approach to maintain the consistency of the data, repeatability of the study and comparability to other studies based on the same maps.…”

“…In Sumatra and Kalimantan, Indonesia, peatlands cover around 15 and 11% of the total land area, respectively, resulting in approximately 13 Mha of peatland (Wahyunto et al 2003(Wahyunto et al , 2004. These peatlands are estimated to contain at least 30 Gt of carbon (Wahyunto et al 2003(Wahyunto et al , 2004Jaenicke et al 2008), which makes them globally considerable carbon deposits. In addition, the tropical peatland ecosystems in Sumatra and Kalimantan sustain unique biodiversity and ecosystem values (Rieley and Page 2005).…”

Peatlands cover around 13 Mha in Sumatra and Kalimantan, Indonesia. Human activities have rapidly increased in the peatland ecosystems during the last two decades, invariably degrading them and making them vulnerable to fires. This causes high carbon emissions that contribute to global climate change. For this article, we used 94 high resolution (10-20 m) satellite images to map the status of peatland degradation and development in Sumatra and Kalimantan using visual image interpretation. The results reveal that less than 4% of the peatland areas remain covered by pristine peatswamp forests (PSFs), while 37% are covered by PSFs with varying degree of degradation. Furthermore, over 20% is considered to be unmanaged degraded landscape, occupied by ferns, shrubs and secondary growth. This alarming extent of degradation makes peatlands vulnerable to accelerated peat decomposition and catastrophic fire episodes that will have global consequences. With on-going degradation and development the existence of the entire tropical peatland ecosystem in this region is in great danger.

“…The world's three major regions of lowland tropical peat, in the Cuvette Centrale, tropical Asia islands, and Western Amazonia, appear to strongly differ (Table 1). Surface topography assessments, using either SRTM or ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer), did not reveal clear domes, where the peat surface increases from the edge to interior of the peatland, as expected from a poorly draining rain-fed system ('raised bogs') 27 , unlike those seen in many, but not all, Western Amazonian 17 , and tropical Asian 18,28 peatlands (Fig. 2).…”

“…Tropical wetlands provide a range of ecosystem services, including ground water recharge, conservation of biodiversity, the removal of excess nutrients from surface waters, and the sequestration and storage of atmospheric carbon (e.g., Silvius and Giesen 1996;Jaenicke et al 2008). However, they are under increasing threat from changes in land use and climate (Chimner and Ewel 2004;Day et alThe inaccessible nature of tropical peatlands has meant that few detailed investigations have been carried out on their formation, ecology, and function (but see Phillips et al 1997;Page et al 1999).…”

Biogeochemical processes along a nutrient gradient in a tropical ombrotrophic peatland

et al. 2010

Biogeochemical properties, including nutrient concentrations, carbon gas fluxes, microbial biomass, and hydrolytic enzyme activities, were determined along a strong nutrient gradient in an ombrotrophic peatland in the Republic of Panama. Total phosphorus in surface peat decreased markedly along a 2.7 km transect from the marginal Raphia taedigera swamp to the interior sawgrass swamp, with similar trends in total nitrogen and potassium. There were parallel changes in the forest structure: basal area decreased dramatically from the margins to the interior, while tree diversity was greatest at sites with extremely low concentrations of readily-exchangeable phosphate. Soil microbial biomass concentrations declined in parallel with nutrient concentrations, although microbes consistently contained a large proportion (up to 47%) of the total soil phosphorus. Microbial C:P and N:P ratios and hydrolytic enzyme activities, including those involved in the cycles of carbon, nitrogen, and phosphorus, increased towards the nutrient-poor wetland interior, indicating strong belowground nutrient limitation. Soil CO 2 fluxes and CH 4 fluxes did not vary systematically along the nutrient gradient, although potential soil respiration determined on drained soils was lower from nutrient-poor sites. Soil respiration responded strongly to drainage and increased temperature. Taken together, our results demonstrate that nutrient status exerts a strong control on above and below-ground processes in tropical peatlands with implications for carbon dynamics and hence long term development of such ecosystems.
