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 |
---|---|---|---|---|
African Penguin Spheniscus demersus | CR | resident (1997) | 700 pairs | A1 |
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.
