Populations meeting IBA criteria ('trigger species') at the site:| Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Peregrine Falcon Falco peregrinus | LC | resident (1995) | 12 pairs | C6 |
| Common Stonechat Saxicola torquatus | LC | resident (2005) | 97–149 pairs | B2 |
