  • 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

Etangs naturels et réservoir artificiel créé au XIX° siècle dont le marnage génère des grèves favorables à Coelanthus subtilis. Cet ensemble de zones humides, bordé en partie par un important massif forestier, constitue une unité paysagère intéressante. Aménagements touristiques existants sur les berges de l'étang et projets d'extension de ces équipements. La gestion des niveaux d'eau du réservoir de Vioreau est liée à la navigabilité du canal de Nantes à Brest : compte tenu du regain d'intérêt pour cette activité, cette gestion ne devrait pas évoluer sensiblement.

4.2 Quality and importance

L'ensemble d'habitats humides rencontrés sur ce site, malgré sa taille réduite, présente un intérêt certain et un bon état de conservation. Le site renferme la seule station connue en région des Pays-de-la-Loire, de Coelanthus subtilis.
