Threats |
| This species is mainly threatened by habitat loss to crop cultivation, and at one location, more than 85% of habitat has already been ploughed. The Caledon Swartberg is also severely infested with alien invasive plants, which have outcompeted most of the natural vegetation on the mountain. On one farm where this species is known to occur, the landowner has made efforts to regularly clear alien plants. |
