  • 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)

3.2 Species referred to in Article 4 of Directive 2009/147/EC and listed in Annex II of Directive 92/43/EEC and site evaluation for them

  • Type: p = permanent, r = reproducing, c = concentration, w = wintering (for plant and non-migratory species use permanent)

  • 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

Ensemble de 13 cavités, jadis exploitées en carrières, creusées dans les calcaires du Bathonien moyen. Les terrains de chasse des chiroptères ont été rajoutés suite à une étude de télémétrie. L'extension du périmètre réalisé en 2016 porte sur des prairies humides et des boisements caducifoliés de pente sur les versants de la vallée. - Cavités trop facilement accessibles à une fréquentation humaine incontrôlée - Dégradations notées sur certaines cavités : feux, dépôts de déchets, comblement...

4.2 Quality and importance

Ce réseau de cavités constitue un ensemble de sites d'hibernation, d'estivage et de mise bas pour 10 espèces de chiroptères dont 5 inscrites à l'annexe II de la directive "habitats". Les effectifs présents confèrent à ce site un intérêt majeur à l'échelle régionale.
