Regnéville havens
General Description
The Regnéville haven is emblematic of the issues of the west coast havens of the Cotentin. The concept of Integrated Coastal Zone Management there makes sense.
This site is subject to a double phenomenon: the filling of the funds havens and erosion on the coastline. Economic activities (shellfish farming, agriculture, tourism) present in the Regnéville haven are dependent on the evolution of the coastal zone and rising sea level.
Haven Regnéville faces the problem of coastal erosion, marine flooding and flooding. Facing these problems, the major issues identified in terms of management of the natural cover two areas:
- The sector Montmartin-on-sea, where salt marshes are attacked almost simultaneously with the dune, the arms of Siena, which shifts to the east. A change of environment would be to consider if the dunes were to disappear, and particularly following repeated phenomena of erosion, marine flooding and flooding.
- Birds. Regnéville Harbour is of international importance for wintering geese Brant. 90% of the National Goose Brant wintering south of the Pointe d'Agon, on the moving part. A modification of the natural environment could have a non-negligible impact on this species.

Impacts on uses could involve:
- The shellfish activity following a change in nutrient inputs through an evolution of hydro-sedimentary Harbour.
- Agriculture: a change in the terrestrial environment following a marine flooding would impact the salt marsh, leading to their demise. This medium represents an area of pasture.
- Tourism: a progressive filling of the harbor would impact recreational activity in terms of access and opportunities for moorings. The proposed "marina copy" of the Community of communes of the canton of Saint-Malo de la Lande was awarded in 2009.
- Infrastructure such as roads, waterfront campsites and Regnéville Hauteville, Regnéville, located in hazardous areas.
The major objective of LiCCo on this site is to educate local stakeholders to anticipate global phenomena in their management. Also, LiCCo will try to educate local stakeholders to another mode of management and develop a monitoring protocol (habitats and sediments).
The project started in 2010 and was finished in 2012.
