Description complète des menacesTexte détaillé évaluation IUCNExpert
In Mozambique on the Tsetserra plateau the montane grassland is threatened by the spread of invasive Pinus patula. There is also a visible impact of grazing by cattle and goats though it is not known if this species is palatable. This species was not recorded during fieldwork in June 2018 (J. Osborne et al. pers. obs. 2018). In Zimbabwe the site on Mt Rukotso is on private farmland, with sheep grazing and potato cultivation. At this site grazing pressure is likely to impact the rocky grassland habitat where this species occurs. In the Nyanga National Park, particularly the southern location of Pungwe Hills, invasive Pinus patula and Australian Wattle (Acacia sp.) may impact on the rocky grassland habitat.
