Other Site Characteristics

Ensemble de dépressions marécageuses et de marais alluvionnaires soumis par le passé à l'influence saumâtre de l'estuaire de la Loire. Le site présente également un intérêt paysager et culturel (du fait des modes particuliers de mise en valeur). Le déclin des activités agricoles observé depuis le milieu du siècle, a conduit à une banalisation et diverses dégradations du milieu : envasement du réseau hydraulique et des plans d'eau, extension des roselières. Les pompages dans la nappe phréatique à l'amont a aussi des conséquences sur le régime hydraulique. La création du parc naturel régional a permis de freiner ces tendances et d'engager diverses actions de restauration.

4.2 Quality and importance

Ensemble de milieux variés : milieux aquatiques et palustres, prairies inondables, bois et fourrés marécageux, tourbières, landes. Les groupements végétaux se répartissent en fonction des gradients d'humidité, d'acidité et de salinité.
