The site was identified as internationally important for bird conservation in 2002 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-bellied Sandgrouse Pterocles orientalis | LC | resident (2001) | 15–20 pairs | C6 |
| Common Crane Grus grus | LC | winter (1996) | 200–300 unknown | B2, C6 |
| Little Bustard Tetrax tetrax | NT | resident (1996) | 200–250 pairs | A1, B2, C1, C6 |
| Great Bustard Otis tarda | EN | resident (2002) | 25–35 birds | A1, C1 |
| Eurasian Spoonbill Platalea leucorodia | LC | breeding (2001) | 50–60 pairs | B1i, B2, C6 |
| Collared Pratincole Glareola pratincola | LC | breeding (2001) | common | C6 |
| Black-winged Kite Elanus caeruleus | LC | resident (2001) | common | B2 |
| Black Kite Milvus migrans | LC | breeding (2001) | common | C6 |
