The site was identified as important in 1998 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species'):Species | Current IUCN Red List Category | Season | Year(s) | Population estimate at site | IBA criteria met |
---|---|---|---|---|---|
Cape Francolin Pternistis capensis | LC | resident | 1998 | present | A3 |
Ground Woodpecker Geocolaptes olivaceus | NT | resident | - | present | A1 |
Cape Rockjumper Chaetops frenatus | NT | resident | 1998 | present | A1, A2, A3 |

Cape Bulbul Pycnonotus capensis | LC | resident | 1998 | present | A3 |
Cape Sugarbird Promerops cafer | LC | resident | 1998 | present | A2, A3 |

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (1998).
