Creeping succulent

Observation - Creeping succulent - Southern Africa. Description: Leaves triangular cross-section, a few teeth on top and outer edges of leaves

Leaves triangular cross-section, a few teeth on top and outer edges of leaves.
I would estimate about 100 plants in this roughly 50m x 50m patch
Red-listed as Endangered
I assume threats would be minimal in Vrolijkheid Nature Reserve
