Towards climate-responsible peatlands management

Klemedtsson, Åsa Kasimir (2014)
Abstract
In the early 1970’s, about 80 ha of rich fen, meadows and wet forest on the margins of the largeand pristine raised bog ‘Komosse’ in Southern Sweden were drained by ditches to promote spruce(Picea abies) growth and forestry production. Draining had a dramatic impact on forest productionon the nutrient-rich peaty soils downhill from the ditches. In 40 years, most of the meadows andfens had turned into dense forest. Because of the high nature conservation value (mainly birdlife) ofthe bog, the entire area (including surrounding forests) was later designated a Ramsar site, a naturereserve, and a Natura 2000 area.In 2012, as part of the management of the Natura 2000 site, ditches were blocked to initiate naturalprocesses to restore habitats on...

Biodiversity is expected to improve andwill be monitored repeatedly. Raising ground water levels in this relatively nitrogen-rich organicsoil affects GHG emissions as calculated by the IPCC Wetland supplement. CH4 emissions increase,however estimates are highly uncertain. The total GHG emissions are reduced by rewetting due todeclinces in CO2 and N2O emissions. (Less)
