  • 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 s'intègre dans un paysage composite où alternent forêts, landes à bruyères, pointements rocheux et pierriers. Il regroupe deux secteurs voisins : la lande de Tertre Bizet, occupant le versant septentrional d'une petite vallée et la Fosse Arthour, exemple typique de cluse profonde entaillée dans les grés armoricains et jonchée d'éboulis sur ses flancs. - Dynamique de fermeture des landes par les ligneux et la fougère grand-aigle. - Fréquentation touristique importante au niveau des habitats rocheux de la Fosse Arthour. - Modifications de la qualité physico-chimique des eaux et/ou des caractéristiques pédologiques.
