The site was identified as internationally important for bird conservation in 2010 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-necked Swan Cygnus melancoryphus | LC | breeding (2007) | 1,000-2,499 birds | A4i |
| Chilean Pigeon Patagioenas araucana | LC | breeding (2007) | present | A2, A3 |
| Black-throated Huet-huet Pteroptochos tarnii | LC | breeding (2007) | present | A2, A3 |
| Chucao Tapaculo Scelorchilus rubecula | LC | breeding (2007) | present | A2, A3 |
| Ochre-flanked Tapaculo Eugralla paradoxa | LC | breeding (2007) | present | A2, A3 |
| Thorn-tailed Rayadito Aphrastura spinicauda | LC | resident (2007) | present | A3 |
| Des Murs's Wiretail Sylviorthorhynchus desmurii | LC | breeding (2007) | present | A3 |
| Patagonian Tyrant Colorhamphus parvirostris | LC | breeding (2007) | present | A3 |
| Fire-eyed Diucon Xolmis pyrope | LC | breeding (2007) | present | A3 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2017) is shown below.
