  • PF: for the habitat types that can have a non-priority as well as a priority form (6210, 7130, 9430) enter "X" in the column PF to indicate the priority form.
  • NP: in case that a habitat type no longer exists in the site enter: x (optional)
  • Cover: decimal values can be entered
  • Caves: for habitat types 8310, 8330 (caves) enter the number of caves if estimated surface is not available.
  • Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation)

Other Site Characteristics

Bel ensemble dunaire avec des dunes mobiles à microtopographie intéressante et dunes boisées très riches. A l'arrière, ensemble de zones humides plus ou moins halophiles selon leur localisation. En se basant sur les laisses des plus hautes mers, le pourcentage de surface marine du site est de 28%. Dégradations diverses liées à la surfréquentation des zones dunaires : piétinnement, voies d'accès, prélèvements sauvages de sable.

4.2 Quality and importance

Ensemble très intéressant, en particulier par la variété des groupements dunaires qui n'ont été que peu dégradés par des boisements. Présence d'une des plus belles stations régionales d'Omphalodes littoralis ; quelques fourrés et boisements de Chêne vert et Pin maritime. Les zones humides arrière-littorales présentent également une bonne diversité avec des prairies, dont certaines sub-halophiles, des marais, roselières, aulnaies.
