  • 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)

  • Group: A = Amphibians, B = Birds, F = Fish, I = Invertebrates, M = Mammals, P = Plants, R = Reptiles
  • S: in case that the data on species are sensitive and therefore have to be blocked for any public access enter: yes
  • NP: in case that a species is no longer present in the site enter: x (optional)
  • Type: p = permanent, r = reproducing, c = concentration, w = wintering (for plant and non-migratory species use permanent)
  • Unit: i = individuals, p = pairs or other units according to the Standard list of population units and codes in accordance with Article 12 and 17 reporting (see reference portal)
  • 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
  • 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); VP = 'Very poor' (use this category only, if not even a rough estimation of the population size can be made, in this case the fields for population size can remain empty, but the field "Abundance categories" has to be filled in)

4.1 General site character

Habitat class % Cover

Total Habitat Cover

Other Site Characteristics

Grotte naturelle développant plus de 2000 mètres de galeries souterraines. La rivière Tardoire coule au pied de la grotte. La grotte est surplombée d'un boisement de chênes où se développe une riche végétation à affinités "montagnardes". La fréquentation non contrôlée du site constitue la plus grande menace sur les populations de chiroptères. Elle peut engendrer de graves dommages aux périodes les plus fragiles (hiver/été).

4.2 Quality and importance

Une des plus remarquables cavités à Chiroptères de France. Située dans les calcaires du karst jurassique de La Rochefoucauld, elle développe un linéaire de galeries de 2 kilomètres accessibles par 6 entrées. Les chauves-souris en exploitent actuellement 3 zones, soit pour l'hivernage, soit pour la reproduction. Les effectifs hivernants, très importants, dépassent les 20.000 individus, dont plus des trois quarts pour le Minioptère de Schreibers.
