Cacouna bog is an abandoned block-cut peatland which has recently (autumn 2006) received management intervention (ditches blocked to impede runoff) with the intent to accelerate spontaneous restoration. Because the peatland is a bog (ombrogenous) the spring snowmelt is a critical source of water that needs to be ...

established on an abandoned mined peatland in eastern Canada had a significant impact on evapotranspiration). Consequently, recently abandoned mined peatlands should be restored rapidly to prevent the establishment and these peatlands are abandoned. The water table in ...

In Canada, 1 x 10^6 t of bog peat are harvested every year. Nowadays, nearly all the peat is harvested by the vacuum method, leaving upon abandonment large areas of peat which are slow to revegetate. Attempts are being made to restore harvested peatlands by raising the water table, applying straw mulch and a layer of surface peat as a source of seeds and ...

Part of an abandoned peat cutting, on a mire in the southwest part of Sweden, was used for intense forest production in 1983. The experimental area, relatively rich in nitrogen, was drained and fertilized with fly ash from forest biomass, raw phosphate an...

Russia possesses vast areas of peatlands and associated paludified shallow peat lands, over 8 and 20% respectively. The country is the largest World peatland nation, and thus could be responsible for the large part of GHG exchange between peatlands and the atmosphere. Russian peatlands present a high variety of ...

Many peatlands previously drained for peat extraction or utilized for agriculture (directly or after partial cutoff) are left abandoned during last decades in Europe, and especially in its eastern part. In the European part of Russia alone, several million hectares of peatlands have been modified for peat extraction and agriculture by ...

As a result of peat extraction, peat production has been finished in Estonia at different times in 154 peat production areas and 9,500 ha (~1% of peatlands) are abandoned, although the peat reserves are not exhausted yet; besides, several areas are not properly recultivated. In addition 12,000 ha of fens (oligotrophic peat layers) are drained and used as ...

This article provides an overview of the effects of land-use on the fluxes of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) and from peatlands in the Nordic countries based on the field data from about 100 studies. In addition, this review aims to identify the gaps in the present knowledge on the greenhouse gas (GHG) balances associated with the land-use of these ...

Climate impact due to the utilisation of peatland from the land use point of view is assessed. The considered peatlands are forestry-drained peatland and cropland (peatland used for agriculture). These peatlands are used for energy production as follows: ...

This paper describes the nature and magnitude of peat soil volume changes and its relation to seasonal changes in water table at an undisturbed bog peatland and on two cutover sections of the same peatland and its effect on hydraulic conductivity. In the latter two sites, operations had ceased 2 and 7 years prior to this study, respectively. The water ...

This article provides an overview of the effects of land-use on the fluxes of methane (CH4), nitrous oxide (N2O) and carbon dioxide (CO2) of peatlands in the Nordic countries presented in about 100 studies. In addition, the article identifies the gaps in the present knowledge on the greenhouse gas (GHG) balances associated with the land-use of these northern ecosystems. ...

At the ecosystem scale, peatlands can be extremely resilient to perturbations. Yet, they are very sensitive to local disturbances, especially mechanical perturbations (e.g. trampling). The effects of these disturbances on vegetation, and potential effects on hydrochemical conditions along the peat surface, however, are largely unknown. We used three research tracks (paths ...

Increasing energy use, climate change, and carbon dioxide (CO2) emissions from fossil fuels make switching to low-carbon fuels a high priority. Biofuels are a potential low-carbon energy source, but whether biofuels offer carbon savings depends on how they are produced. Converting rainforests, peatlands, savannas, or grasslands to produce food crop based biofuels in Brazil, ...

Reducing the greenhouse gas (GHG) emissions from natural and anthropogenic environments has become a key issue over the last decades. In Denmark the management of the wetlands is playing a key role in these attempts. The wetland area of Skjern Meadows in the western part of Denmark is one of the best known examples of peatland restauration in northern Europe. The valley of the ...
