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 |
|---|---|---|---|---|---|
| Egyptian Vulture Neophron percnopterus | EN | breeding | 2009 | 2 breeding pairs | A1, C1, C6 |
| Short-toed Snake-eagle Circaetus gallicus | LC | breeding | 2009 | min 7 breeding pairs | C6 |
| Middle Spotted Woodpecker Leiopicus medius | LC | resident | 2009 | 791-801 breeding pairs | 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 (2008) is shown below.
