Data Zone
The site was identified as important in 2011 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species') at the site:| Species | Red List1 | Season | Year(s) | Size | IBA criteria |
|---|---|---|---|---|---|
| Bearded Vulture Gypaetus barbatus | NT | resident | 2010 | 1 breeding pairs | B2, C2, C6 |
| Egyptian Vulture Neophron percnopterus | EN | breeding | 2008 | min 8 breeding pairs | A1, C1, C2, C6 |
| Golden Eagle Aquila chrysaetos | LC | resident | 2009 | 8-10 breeding pairs | C6 |
| Peregrine Falcon Falco peregrinus | LC | resident | 2008 | min 15 breeding pairs | C6 |
| Red-billed Chough Pyrrhocorax pyrrhocorax | LC | resident | 2006 | 115-220 breeding pairs | B2, C2, C6 |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2011) may differ.
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2011. The most recent assessment (2007) is shown below.
