Lode et al 2012: Up-Scaling Possibilities of Environmental Changes on Long-Term Peatland Management at Porla Mire
Summary:
Theme I. Inventory, stratigraphy and conservation of mires and peatlands
SUMMARY
Landscape study of 116 ha Porla mire showed a drastic changes on 77% of the mire total land cover since 1864. Water supply for the rewetting is telmatic and the water of the lake outlets having rather small changes during ten year inundation in comparison of the water formed in poor-fen. However, the annual outlet quantities seem to be lowered due to the increased part of the opened water surfaces. The coverage of the most GHG emitting part constitutes about 40% or 46 ha from contemporary peatland area. Only about 8 ha of the lakes water surface and 3 ha from the non-managed poor-fen part could be referred to the low GHG emitters, outside the tree or other plant covered area.
