Peatland Restoration in Sweden--From peat cutting areas to shallow lakes -after-use of industrial peat sites

摘要

Regeneration and Wise Use of peatlands after peat harvesting is highlighted in Sweden. Two peatlands close to each other, Porla bog and West fen, in south-central Sweden were investigated before and up to nine years after re-wetting, in 1999 and 2000. Considerable changes in site conditions had occurred during the extraction of peat and new prerequisites existed as the very old peat bottom horizons were exposed to land surface re-colonisation. Peatland restoration was therefore difficult and management for wise after-use aimed initially to focus on re-wetting for restoration of the hydrology that would provide new conditions for biogeochemistry and biodiversity.
