  • 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)
  • 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
N22100.00

Total Habitat Cover

100

Other Site Characteristics

La géologie du site repose sur deux formations de craies séparées par une surface indurée. La couche inférieure dénommée "craie glauconieuse" a subi les attaques de l'eau souterraine, provoquant ainsi une dissolution de la craie, matérialisée par des fissures puis des galeries. Cette cavité a été générée par l'extraction de la pierre de taille. -menaces sur habitats participant à la fonctionnalité du milieu : paysages semi-ouverts, lisières, boisements feuillus, prairies, friches et vergers. -pratiques agricoles peu respectueuses du milieu : agriculture intensive, labourage, pesticides

4.2 Quality and importance

Le site de loisail se place comme le premier lieu d'hibernation en Basse-Normandie par le nombre total d'individus de chauves-souris. 10 espèces sur les 17 présentes en Normandie, ont été observées dans cette cavité.
