  • 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)

Other Site Characteristics

Le site est inclu au sein d'une ancienne carrière de craie dont la production a cessé en 1998. Celle-ci est actuellement en cours de réaménagement. Ce site constitue un habitat de subsitution pour le Sisymbre couché (Sisymbrium supinum). Le Sisymbre couché est particulièrement menacé par la fermeture des milieux et la stabilisation des terrains constituant actuellement des éboulis crayeux.

4.2 Quality and importance

Il s'agit d'une ancienne carrière dont les activités d'extraction ont permis le développement de milieux pionniers variés et en constante évolution. De nombreux éboulis crayeux présents sont alimentés par l'effrondrement régulier d'une falaise. Le Sisymbre couché a pu se développer sur ces éboulis. Actuellement, les activités d'extraction ayant cessé, la carrière est en cours de réaménagement. Un programme d'aménagement a été établi en concertation avec le Conservatoire botanique national du Bassin parisien afin de conserver la population de sisymbre.
