  • 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

Le site est localisé sur 2 domaines biogéographiques: 24% pour le domaine atlantique et 76% pour le domaine méditerranéen. D'un point de vue géologique, ce site repose sur des terrains très anciens du précambrien et du paléozoïque, qui comprennent notamment des grès, des schistes et des amphibolites. Tourisme aquatique localisé en bordure du Tarn dans les secteurs accessibles et autorisés.

4.2 Quality and importance

Vallée encaissée offrant une grande diversité de situations aquatiques et géologiques (terrains calcaires et acides) entrainant une végétation originale. De nombreux secteurs sont inaccessibles, présentant des pentes abruptes au dessus du Tarn. Boisements de taillis de chênes et de châtaigniers, landes acidophiles et ripisylves. Présence de grottes à chauves-souris. Population remarquable d'Odonates rares, notamment Macromia splendens. Colonisation en cours du Castor, en limite Sud-Ouest absolue de son aire en France, suite à des réintroductions en amont dans le bassin du Tarn et sur la Dourbie. La loutre recolonise petit à petit les rivières.
