Data Zone
The site was identified as internationally important for bird conservation in 2000 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 |
|---|---|---|---|---|
| Rock Partridge Alectoris graeca | NT | resident (1996) | 70–110 pairs | B2 |
| Black Grouse Lyrurus tetrix | LC | resident (1996) | 120–200 pairs | B2 |
| Eurasian Wryneck Jynx torquilla | LC | breeding (1996) | 20–30 pairs | B2 |
| Eurasian Green Woodpecker Picus viridis | LC | resident (1996) | 50–150 pairs | B2 |
| Yellow-billed Chough Pyrrhocorax graculus | LC | resident (1996) | 200–300 pairs | A3 |
| Wallcreeper Tichodroma muraria | LC | resident (1996) | present | A3 |
| Ring Ouzel Turdus torquatus | LC | breeding (1996) | 200–400 pairs | B3 |
| Rufous-tailed Rock-thrush Monticola saxatilis | LC | breeding (1996) | 20 pairs | B2 |
| Alpine Accentor Prunella collaris | LC | resident (1996) | 150–250 pairs | A3 |
| White-winged Snowfinch Montifringilla nivalis | LC | resident (1996) | 100–250 pairs | A3 |
| Citril Finch Carduelis citrinella | LC | breeding (1996) | 100–200 pairs | A3 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2012) is shown below.
