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 |
|---|---|---|---|---|
| Little Bustard Tetrax tetrax | NT | winter (2006) | min 450 birds | A1, C1 |
| Little Bustard Tetrax tetrax | NT | resident (2009) | present | A1, C1 |
| Great Bustard Otis tarda | EN | resident (2011) | 170–190 birds | A1, C1, C6 |
| Black-crowned Night Heron Nycticorax nycticorax | LC | breeding (2007) | min 173 pairs | C2, C6 |
| Black-winged Stilt Himantopus himantopus | LC | breeding (2007) | min 84 pairs | C6 |
| Western Marsh-harrier Circus aeruginosus | LC | winter (2007) | min 42 birds | C6 |
| Western Marsh-harrier Circus aeruginosus | LC | resident (2007) | min 23 pairs | C6 |
| Red-billed Chough Pyrrhocorax pyrrhocorax | LC | resident (2003) | min 25 pairs | 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.
