The pressure and disruption weighing on fens and associated marshland generally lead to a homogenisation of plant life and the disappearance of typical peatland vegetation.

LIFE Anthropofens aims to preserve the different stages in the evolution of peat environments and to develop methods of management aiming to improve the state of conservation of all alkaline fen habitats.

To restore and preserve the mosaics of peat habitats in a lasting way, the nine LIFE Anthropofens beneficiaries will carry out initiatives aiming to :

  • Foster areas linking aquatic and lands areas by rejuvenating transition mires (7140) – removing the top layer from the soil – over 1,800 m² and supplying 600 m of fascines;
  • Restore the peat horizon in alkaline fens (7230) by removing the top layer of the soil in an area of 23 hectares;
  • Open up 195 hectares of peatland by cutting down trees and/or clearing vegetation in favour of herbaceous plants: molinia meadows (6410), transition mires (7140), calcareous fens (7210*) and alkaline fens (7230) and by encouraging the successive peatland phases;
  • Recreate 19.4 hectares of molinia meadows on peaty limestone or silty clay soils (6410) by reopening habitats (cutting and clearing vegetation and cropping roots) and spreading hay;
  • 18 km of fencing will be set up in different forms (confinement pens, gates, etc.) to develop management by extensive pasturing;
  • Convert 15.9 hectares of poplar groves into bog woodland (91D0*) and alluvial forests with black alder and European ash (91E0*) and to promote the maturing process in 31 hectares by leaving them free to evolve.

Some projects will be completed by replanting "engineer" species, which are collected and grown beforehand, in transition mires in order to improve the development of the habitat.

Work to boost species characteristic of alkaline fens will also be carried out (sampling, cultivation and replanting on site) to guarantee the survival of endangered species.

It is also planned to draw up five management plans that will include the results obtained during the first few years of the LIFE Anthropofens programmes.

All the actions aiming to restore and preserve the peatland mosaics are backed by initiatives to improve water management.
