  • 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

Ensemble hydrographique comportant les cours d'eau et les parcelles adjacentes à ceux-ci. Les principales menaces pesant sur ce site sont: - la dégradation physico-chimique de l'eau par pollutions de diverses origines - la modification des conditions d'écoulement (recalibrage, barrage...) - l'altération des habitats par des aménagements non encadrés, ou des pratiques agricoles non adaptées (divagation des animaux dans les cours d'eau notamment), ou par une altération de la rypisylve qui provoque des phénomènes d'érosions entrainant des matières en suspension qui colmatent les fonds

4.2 Quality and importance

Site composé d'un ensemble hydrographique et des parcelles adjacentes aux cours d'eau. Ceux-ci abritent des espèces remarquables d'intérêt européen : Margaritifera margaritifera, Austropotamobius pallipes, Cottus gobio, Lampetra planeri.
