“…Drainage of peatlands reduces the emissions, because emerging aerobic conditions suppress the activity of methanogens (Kettunen et al 1999, Freeman et al 2002, while concurrently, methanotrophs are not affected much (Roulet et al 1993, Sundh et al 1994. The aerobic conditions also lead to enhanced decomposition rates, which is associated with a decrease in the amount of substrate available for CH 4 production (Komulainen et al 1998, Huttunen et al 2003b, Basiliko et al 2007, Eriksson et al 2010.…”

“…After a successful rewetting carbon cycle typical for mire ecosystem is slowly revitalized. However, the few studies that have assessed CH 4 emissions on restored peatlands indicate that although restoration increases the emissions (Tuittila et al 2000, Waddington andDay 2007) they remain lower than for pristine mires, at least during the first two-three years after restoration (Komulainen et al 1998, Tuittila et al 2000. The reason for the low rate of CH 4 release after rewetting is not fully understood, however, one reason could be the very slow re-establishment of methanogenic bacteria after prolonged aeration (Tuittila et al 2000).…”

“…and other forest mosses. Vegetation changes after drainage are described in more detail by Laine et al (1995a), and after restoration by Komulainen et al (1998).

“…These sites were selected on the basis of extensive earlier studies (e.g. Laiho, 1997;Komulainen et al, 1998) to ensure comparability of sites as much as possible. Five peatland sites were sampled: a pristine undrained tall-sedge pine fen site, comparable sites drained for forestry 12, 26 and ca.…”

We investigated the within-site distribution of Enchytraeidae, Collembola, Oribatida, Mesostigmata and Prostigmata relative to varying water level and substrate quality on pine mire sites forming a drainage succession continuum. Collembolans were most intolerant of wetness, favoring drier locations at all stages of the drainage succession. In general, the effect of water level variation on the within-site distribution of the soil fauna was strongest when the site was at an early stage of either progressive or regressive water level change. When the average water level was below 20 cm, it no longer had a significant effect on the distribution of mites, but still affected that of Enchytraeidae and Collembola. Boron was positively correlated with faunal density in several cases, and thus may be the growth limiting nutrient affecting substrate quality for decomposers in these sites. The overall changes in the soil mesofauna in drained peatlands depicted here show that these peatland forests are converging ecologically on upland forests where decomposition in general is much faster than in pristine peatlands. The change caused by restoration shows how labile these ecosystems are also with respect to the mesofaunal community.

“…To date, peatland research has strongly focused on boreal and temperate peats, with important knowledge developments in aspects such as peatland function and characteristics (see for example Heikurainen & Päivänen, 1970;Hogg et al 1992;Bonnett et al 2006), and management techniques for restoration and rehabilitation (see Komulainen et al 1998;Shantz & Price 2006;Worrall et al 2007). …”

Research agendas for the sustainable management of tropical peatland in Malaysia

et al. 2014

View full text Add to dashboard Cite

SUMMARYThere is a need for coordinated research for the sustainable management of topical peatland. Malaysia has 6% of global tropical peat by area and peatlands there are subject to land use change at an unprecedented rate. This paper describes a stakeholder engagement exercise that identified 95 priority research questions for peatland in Malaysia, organized into nine themes. Analysis revealed the need for fundamental scientific research, with strong representation across the themes of environmental change, ecosystem services, and conversion, disturbance and degradation. Considerable uncertainty remains about Malaysia's baseline conditions for peatland, including questions over total remaining area of peatland, water table depths, soil characteristics, hydrological function, biogeochemical processes and ecology. More applied and multidisciplinary studies involving researchers from the social sciences are required. The future sustainability of Malaysian peatland relies on coordinating research agendas via a 'knowledge hub' of researchers, strengthening the role of peatlands in land-use planning and development processes, stricter policy enforcement, and bridging the divide between national and provincial governance. Integration of the economic value of peatlands into existing planning regimes is also a stakeholder priority. Finally, current research needs to be better communicated for the benefit of the research community, for improved societal understanding and to inform policy processes.
