  • 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)

3.2 Species referred to in Article 4 of Directive 2009/147/EC and listed in Annex II of Directive 92/43/EEC and site evaluation for them

Other Site Characteristics

Chaîne de marais formés par les marais arrières dunaires, les palus (vastes étendues de prairies humides), les mattes (zones bordant l'estuaire de la Gironde) et deux marais maritimes au nord du site. Forte déprisse agricole en partie compensée par une maitrise foncière des chasseurs de gibier d'eau. Forte sensibilité des habitats et des espèces à la gestion des niveaux d'eau et de la qualité de l'eau.

4.2 Quality and importance

Importante diversité des habitats humides du fait de trois grands types d'alluvions : tourbeuses, fluviatiles et fluviomarines. Flore et faune riches, liées aux milieux humides, dont le très rare Graphoderus bilineatus.
