The site was identified as internationally important for bird conservation in 2008 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 |
|---|---|---|---|---|
| Straight-billed Reedhaunter Limnoctites rectirostris | NT | resident (1966–2005) | 90 birds | A1, A2 |
| Sulphur-throated Spinetail Limnoctites sulphuriferus | LC | resident (1966–2005) | present | A3 |
| Black-and-white Monjita Xolmis dominicanus | VU | resident (1966–2004) | 200 birds | A1 |
| Saffron-cowled Blackbird Xanthopsar flavus | EN | resident (1996–2008) | 130 birds | A1 |
| Chestnut Seedeater Sporophila cinnamomea | VU | breeding (2006) | present | A1, A2, A3 |
| Marsh Seedeater Sporophila palustris | EN | breeding (2005–2008) | 27 birds | A1, A2, A3 |
| Marsh Seedeater Sporophila palustris | EN | breeding (1999) | 2 birds | A1, A2, A3 |
| A4iii Species group - waterbirds | n/a | non-breeding (2007) | 48,900 birds | A4iii |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2008. The most recent assessment (2013) is shown below.
