Justification | Tritoniopsis toximontana is a range-restricted species, with an extent of occurrence (EOO) of 17 km². It is limited to a small proportion of one vegetation type (Bokkeveld Sandstone Fynbos). It is fairly common in the correct habitat and is not threatened as it occurs in a rocky non-arable habitat. It is therefore listed under the IUCN 3.1 Criteria, globally, as Least Concern but is nationally categorised as Rare. |
