Spanish ibex
The heavy depopulation has favored wildlife, so that one of the last colonies of griffon vultures in Europe is in the Iberian System. Wolves and eagles ("Aquila chrysaetos", "Hieraaetus fasciatus", "Hieraaetus pennatus", "Circaetus gallicus") are also relatively common in the lonely heights. Among the mammals, the Spanish ibex, roe deer, wild boar, European badgers, common genets, among others, have their habitat in many of these desolate mountain ranges.
