Justification | Osteospermum ilicifolium has a restricted distribution range, with an extent of occurrence (EOO) of 14 723 km². It is declining in parts of its range, but is also very common, particularly in montane areas where there are few threats, and is therefore not in danger of extinction. It is listed as Least Concern. |
