Industrial peat extraction Since 1950 industrial peat extraction for gardening Until 2003 200.000 m³ peat were extracted per year Resources 8 million m³
Planning EU Habitat area Criterion for pointing out: - Raised bog - Raised bog with growth of trees - Different types of dunes - Etc. EU Bird Protection Criterion for pointing out: - Wood Sandpiper - Black Stork - Crane - Golden eagle - Etc. Nature Conservation project Project for a National Park
Initiatives to create a coherent nature reserve composed by bog areas EU Habitatdirective forces authorities to act The Danish Government is submitted to the EU - Commission The County has worked out a nature restoration project
Investigations Intact raised bogs: - State of preservation - Tofte Bog (Staatsbosbeheer, Holland) Drained raised bogs: - Chemistry and Sphagnum structures - Closeness of mineral soil - Possible water levels - Possibilities for promoting sphagnum growth - Possibilities for promoting other types of nature
State of preservation of the bogs The bogs are in a different state of preservation not a stable state The bogs are drying out Drainage and peat extraction are the most important threats
Experiments Experiment on peat extraction areas for sphagnum growth (Cuspidatum)
Alternatives
Project aims and strategies In accordance to EU-Habitat Directive: Protection of remnant bogs Connection of remnant bogs Destribute sphagnum growth Compensate insufficient state of preservation Change suitable peat extraction areas to promote sphagnum growth Change suitable peat extraction areas to other types of nature
Project means Stop drainage on the bogs Stop peat extraction 250 500 m from bogs Stop peat extraction closer than 0,5 m and 1 m from mineral layer Remove topsoil from cultivated areas Raise ground water level Possible building of dams along bog edges
Cross section Present Thesurfaceoftheearth Ground water level Future: Ground water level
Results Temporary stop for peat extraction on most areas Limitation and restrictions on other peat extraction areas Legal period about privilege and economical compensation has started Until now we have made investigations and plans In future we will realise the plans Create a huge nature reserve consisting of 18.100 ha On Land 07.850 ha On sea 10.250 ha From this 5.000 ha with raised bogs and wetlands
