The biodiversity here is amazing. The birds of prey take advantage of rising air currents to its gliding and from open spaces for hunting. With some luck one can observe the peregrine falcon, the Bonelli’s eagle and the eurasian eagle owl, and species such as the montagu’s harrier, the black kite, the common buzzard, the common-kestrel, the short-toed snake eagle, tawny owl and the little owl are frequent. In the shale cliffs and greywacke develops very rare rupicolous plants such as rocky germander, the murbeckiella or the giant eryngo plant with more than 1 meter high of the umbelliferae family. The embedded valley is still refuge to a plant of the continental laurel forest – the pontic rhododendron, a very rare iberian endemic species.
