  • 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)

  • Abundance categories (Cat.): C = common, R = rare, V = very rare, P = present - to fill if data are deficient (DD) or in addition to population size information

Other Site Characteristics

Présence de ruisseaux, sources et mares en tête de bassin versant du ruisseau de l'Aber Vrac'h. Une gestion conservatoire (fauche, pâturage) est opérationnelle, limitant les risques de dégradation éventuels volontaires ou par abandon des pratiques agro-pastorales.

4.2 Quality and importance

Plus importante zone humide de l'intérieur du Léon abritant un ensemble complexe de landes tourbeuses à mésophiles (en partie sous pinède claire), de groupements de bas-marais acides et de prairies humides à facies variés. Le site comporte en particulier des landes humides tourbeuses à sphaignes (habitat d'intérêt communautaire, prioritaire) avec présence de la sphaigne de la Pylaie en limite ouest de son aire de répartition nationale (limitée à la Bretagne occidentale). 83 espèces d'oiseaux ont été recensées dont le Tarier des prés (Saxicola rubetra) nicheur, 6 espèces d'amphibiens. L'inventaire des invertébrés est en cours. La présence du Damier de la Succise (Euphydrias aurinia) est avérée (papillon protégé en France et d'intérêt communautaire).
