Restore/create peatland vegetation (multiple interventions) Peatland Conservation

A controlled study in 1997–2014 in a degraded fen in France (Pôle-Relais Tourbières 2016) reported that following restoration by multiple interventions, plant species richness and cover of fen-characteristic plants increased. No statistical tests were carried out. Fifteen years after intervention, there were 20 plant species in the fen (vs 12 when intervention began). Cover of fen-characteristic plants, including sedges Carex spp., was 50% (vs 2% when intervention began and vs 12% in an unrestored area of the fen). Restoration of a drained, abandoned, overgrown fen began in 1997–1999. The fen was rewetted by remeandering an adjacent river. Willow shrubs were cut and removed. Existing herbaceous vegetation and surface peat were shredded. Each summer between 1999 and 2004, the fen was grazed by horses. From 2004, a four year cycle of grazing-rest-mowing-rest was implemented in a mosaic across the fen. Between 1999 and 2014, cover of plant community types was estimated in the managed area (in four quadrats along a transect) and adjacent unmanaged fen (details not reported).
