The site was identified as internationally important for bird conservation in 2009 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 |
---|---|---|---|---|
Baudin's Black-cockatoo Zanda baudinii | CR | breeding (2004–2008) | 3 nests | A1, A2, A3 |
Carnaby's Black-cockatoo Zanda latirostris | EN | breeding (2004–2008) | 20 nests | A1, A3 |
Red-capped Parrot Purpureicephalus spurius | LC | resident (2003–2008) | common | A3 |

Rufous Treecreeper Climacteris rufus | LC | resident (2003–2008) | uncommon | A3 |
Red-winged Fairywren Malurus elegans | LC | resident (1998–2008) | abundant | A2, A3 |
Western Spinebill Acanthorhynchus superciliosus | LC | resident (1998–2008) | abundant | A3 |
Western Thornbill Acanthiza inornata | LC | resident (1998–2008) | common | A3 |
