Justification | A localized (EOO 101 km²) habitat specialist, occurring in small subpopulations numbering fewer than 500 mature individuals at nine locations on the Vredenburg Peninsula. The population size is estimated as fewer than 2000 mature individuals and continue to decline due to ongoing habitat loss to urban expansion and mining. |
