Première mention de la Veloutée moine, Ashfordia granulata (Alder, 1830) (Gastropoda, Hygromiidae) dans la région Nord - Pas-de-Calais (France)Keywords: Mollusca , Nord - Pas-de-Calais , Ashfordia granulata , first mention , underground water seepage , cliff base , sand dunes , coast Abstract: Widely distributed in England, Ashfordia granulata is known from France in the Somme, Bretagne and Basse-Normandie regions. This note describes the first reporting of the species in the Nord-Pas-de-Calais region. It was found in seepages between beach and sand dunes at Pointe aux Oies, between Wimereux and Ambleteuse. This population is restricted to a few square meters and was not found in similar biotopes nearby. Trampling by hikers and marine erosion are the major threats to this isolated population.
