Justification | This species has an extent of occurrence (EOO) of 11 259 km², and an area of occupancy (AOO) of 80 km². It is known from 14 locations in lowland habitats, with the majority of subpopulations occurring in the Vredenburg peninsula area. This area is under severe pressure from coastal development and suitable habitat is declining as a result. It is therefore listed as Near Threatened, almost meeting criteria B to be listed as Vulnerable. |
