The site of Regnéville-sur-Mer
With an area of 8.5 hectares, these zones of wetland prairies bordered by limestone walls were acquired by the county of La Manche in 1993 and 1994. The site is managed by the Syndicat Mixte Littoraux de la Manche (SyMEL).
The fauna and flora of the wetland prairies
In the middle of these prairies there are three ponds, fed by water trickling from the junction of the Montmartin limestone and a more impermeable rock, the conglomerate of Hyenville. These wetland areas are home to a rich fauna such as the Great crested newt, the European tree frog, dragonflies and other aquatic insects. The flora also possesses some remarkable species including the Yellow water lily (Nuphar lutea) and horned pondweed (Zannichellia palustris).
