The site was identified as internationally important for bird conservation 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 |
---|---|---|---|---|---|
Cinereous Vulture Aegypius monachus | NT | resident | 2006 | 87–100 pairs | A1, A4ii, B1iii, B2, C1, C2, C6 |
Spanish Imperial Eagle Aquila adalberti | VU | resident | 2009 | min 6 pairs | A1, B2, C1, C2, C6 |
Red Kite Milvus milvus | LC | resident | 2010 | 20–30 pairs | A1, B2, C1, 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.
