  • 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

Espacio ubicado dentro de las sierras mesozoicas de naturaleza carbonatada de la Ibérica Zaragozana, con superficies de erosión en calizas que se sitúan en torno a los 1100-1200m de altitud y que se prolongan por la provincia de Guadalajara. El río Piedr

4.2 Quality and importance

Espacio de gran interés geomorfológico y biogeográfico por la presencia de un cañón fluviokárstico excavado por el río Piedra entre relieves calcáreos, formando paredones verticales con una flora rupícola asociada. Hay que destacar las formaciones boscosa
