The site was identified as internationally important for bird conservation in 1998 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 |
---|---|---|---|---|
Cape Spurfowl Pternistis capensis | LC | resident (1998) | present | A3 |
Cape Rockjumper Chaetops frenatus | NT | resident (1998) | present | A1, A2, A3 |
Victorin's Warbler Cryptillas victorini | LC | resident (1998) | present | A2, A3 |
Cape Bulbul Pycnonotus capensis | LC | resident (1998) | present | A3 |
Cape Sugarbird Promerops cafer | LC | resident (1998) | present | A2, A3 |
Orange-breasted Sunbird Anthobaphes violacea | LC | resident (1998) | present | A2, A3 |
Protea Canary Crithagra leucoptera | NT | resident (1998) | present | A1, A2, A3 |
Cape Siskin Crithagra totta | LC | resident (1998) | present | A1, A2, A3 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1998. The most recent assessment (2013) is shown below.
