  • 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

Milieux dunaires importants reposant sur schistes et localement calcaires ; à l'arrière, vaste ensemble de marais salés avec entrées d'eau contrôlées. Les ensembles dunaires sont menacés par la surfréquentation : piétinement, pratiques diverses (vélo, parapente) non contrôlées ; les marais sont pour la plupart abandonnés, ainsi que le pâturage des "levées" ; le développement de la pisciculture dans les anciens bassins des salines peut entraîner des modifications de milieux dont l'impact reste à évaluer.

4.2 Quality and importance

Belles étendues de dunes mobiles et fixées avec de nombreuses dépressions humides, dont certaines tourbeuses. Très belle zonation de la végétation de ces milieux. Forêt plantée de Pins maritimes depuis le XIX° siècle avec diverses espèces d'orchidées en sous-bois et quelques Chênes verts spontanés. Marais salants pour la plupart abandonnés, mais avec belle végétation halophile ; quelques marais doux au contact des massifs dunaires ; quelques pelouses calcaires près des marais.
