Justification | Known from two locations, at Riverlands and at Rondevlei (EOO<20 km²). It has lost over 70% of its habitat in the past 60 years to invasive alien acacias and agriculture. It is still declining at Rondevlei, a private farm which is not well managed, while at Riverlands, constant alien clearing is required to stop aliens from degrading the habitat of this species. |
