Data Zone
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 List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Black Stork Ciconia nigra | LC | breeding (2011) | min 5 pairs | B1i, C2 |
| Eurasian Eagle-owl Bubo bubo | LC | resident (2004) | 30–35 pairs | B2, C2, C6 |
| Spanish Imperial Eagle Aquila adalberti | VU | resident (2007) | present | B2 |
| Spanish Imperial Eagle Aquila adalberti | VU | non-breeding (2011) | present | B2 |
| Golden Eagle Aquila chrysaetos | LC | resident (2008) | 7–8 pairs | C6 |
| Booted Eagle Hieraaetus pennatus | LC | breeding (2009) | min 60 pairs | B1iii, B2, C2 |
| Red Kite Milvus milvus | LC | resident (2011) | min 56 pairs | A1, B2, C1, C6 |
| Black Kite Milvus migrans | LC | breeding (2004) | 100–110 pairs | B2, C6 |
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.
