Site details


Site description: An arid river valley with rocky massifs, covered by broadleaved forestand dry grassland on the ridges of the hills. Forests are dominated by Quercus, Carpinus and Acer.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Additional biodiversity: The area is one of the most important breeding sites for Tadorna ferruginea and Buteo rufinus in the country. Gyps fulvus and Aquila chrysaetos used to breed in the area many years ago. Significant proportion (³1%) of national population breeding at site: Neophron percnopterus (1 pair), Circaetus gallicus (1 pair), Aquila pomarina (1 pair), Hieraaetus pennatus (1 pair), Bubo bubo (3 pairs).
