Not back to their old selves – rewetted peatlands require functional understanding for sound management

Jüergen Kreyling Franziska Tanneberger Florian Jansen Sebastian van der Linden Hans Joosten

<p><strong>Peatlands, in particular temperate, groundwater-fed fens, have widely been drained for agriculture. However, draining peatlands turns them into globally relevant carbon sources, diminishes water holding capacity and nutrient removal at landscape scales, and threatens their native biodiversity. Consequently, formerly drained peatlands are now being re-wetted in large numbers for mitigating climate change, combating eutrophication, managing water and preserving biodiversity. A comparison between >300 rewetted peatlands to > 260 close to natural peatlands across temperate Europe, however, indicates that rewetting drained peatlands induces a helophytization (a dominance of tall, graminoid wetland plants) with no trend back to their former biodiversity (vegetation) and function (geochemistry, hydrology) for at least several decades. An understanding of these locally novel ecosystems is required for sound and sustainable management of their ecosystem services.</strong></p>

International carbon policies as a new driver for peatland restoration

Cambridge University Press eBooks (2016)

Hans Joosten John Couwenberg Moritz von Unger

When – in 2006 – experts and advocacy groups for the first time raised the issue of GHG emissions from degraded peatlands at the United Nations Framework Convention on Climate Change (UNFCCC), they met with negotiators, many of whom had never heard of 'peat' in the first place. Six years later, the UNFCCC allowed countries to comply with their reduction commitments by peatland rewetting and included peat soils in the REDD+ mechanism to reduce emissions from tropical deforestation. After years of neglect, peatlands have gained the attention that they deserve in the face of their enormous emissions and mitigation potential (Chapter 4).

Ecosystem services, degradation and restoration of peat swamps in the South East Asian tropics

Cambridge University Press eBooks (2016)

The coastline of Sarawak appears to the casual observer monotonous and uninteresting. A coastal fringe of littoral forest or mangrove merges quickly into a flat plain behind which the inland mountain ranges appear in the distance. […][F]rom the mouth of the Batang Lupar to Kedurong Point – a distance of 200 miles – there is no high ground in the vicinity of the coast. Apart from the immediate coastal or riparian fringe, subject to regular or occasional inundation, the whole plain has been and still is largely covered in swamp forest growing on peat, recorded depths of which may exceed fifty feet.(Anderson 1963).

Vegetation characteristics and eco-hydrological processes in a pristine mire in the Ob River valley (Western Siberia)

Plant Ecology (2007)

Aafke M. Schipper Ron Zeefat Franziska Tanneberger Jeroen P. van Zuidam Wulf Hahne

Relations between vegetation characteristics and eco-hydrological processes were assessed in a pristine mire in the valley of the Ob River (Western Siberia). Along a transect from the terrace scarp to the river, field data were collected on vegetation composition, peat stratigraphy, peat chemistry, hydrology and hydrochemistry. Based on floristic composition, eight vegetation communities were distinguished. Hydraulic head measurements were used to obtain an indication of groundwater flow directions. The water balance of the mire was calculated with a two-dimensional steady-state numerical groundwater model. Water types were defined based on cluster analysis of hydrochemical data. The results revealed that the dominant hydrological factor in the Ob mire is the discharge of groundwater, which supplies about threefold more water than net precipitation. Although the discharge flux decreases with increasing distance from the terrace scarp, high water levels and a "groundwater-like" mire water composition were observed in the major part of the study site. Precipitation and river water play only a minor role. Despite dilution of discharging groundwater with rainwater, spatial differences in pH and solute concentrations of the surficial mire water are small and not reflected in the vegetation composition. Although small amounts of silt and clay were found in the peat in the proximity of the river, indicating the occurrence of river floods in former times, no river-flood zone could be recognized based on hydrochemical characteristics or vegetation composition. A comparison of the Ob mire with well-studied and near-natural mires in the Biebrza River valley (Poland) revealed substantial differences in both vegetation characteristics and the intensity and spatial pattern of eco-hydrological processes. Differences in the origin and ratios of water fluxes as well as a dissimilar land use history would seem to be key factors explaining the differences observed.
