Habitat class % Cover
N022.00
N0698.00

Total Habitat Cover

100

Other Site Characteristics

Lit mineur d'un grand fleuve + berges et digues + zones de divagation en amont du site uniquement. Amont du site = les saligues : divagations du lit mineur avec reprise et dépôt de matériaux ; lit très mobile en constant renouvellement ; connexion/déconnexion régulière d'annexes hydrauliques. Partie intermédiaire = les barthes : dynamique fluviale diminuée par de nombreux aménagements ; connexions possibles vers de grandes plaines inondables (barthes de l'Adour). Aval du site = zone d'estuaire : transition eaux douces/eaux salées ; intérêt patrimonial fort pour les espèces de migrateurs amphihalins notamment. Forte pression anthropique sur ce fleuve très aménagé : ouvrages transversaux, ouvrages latéraux vers les affluents et annexes hydrauliques, digues, etc. Problèmatique de qualité et quantité d'eau (notamment en période estivale).

4.2 Quality and importance

Site important pour les poissons migrateurs, l'Angélique des estuaires (espèce endémique) et le Vison d'Europe notamment.
