État de la populationExpert
There is no detailed population information available. However, Browning and Gordon-Gray (1996) noted that subpopulations are mostly very localised, often small, and in KwaZulu-Natal (South Africa), frequently limited to a few scattered, solitary plants. A slightly more extensive subpopulation occurs the Chimanimani National Park (Zimbabwe; Browning and Gordon-Gray, 1996). Several (small) subpopulations are also found in Chimanimani Mts of Mozambique, at Mt Gorongosa and Serra Choa. No information is available for Mount Mulanje subpopulations. Concerning the status of the species in South Africa, Browning and Gordon-Gray (1996) wrote: “Active regeneration of young plants is nowhere clearly evident. The species gives evidence of being relictual and should be considered endangered”.

Description complète des menacesExpert
More research is needed to investigate threats; J. Browning (pers. comm.) noted that in KwaZulu-Natal plantations of alien tree species have reduced its habitat extent. Several threats to the Mount Mulanje area have been reported of which some can affect the distribution range and habitat of Costularia natalensis, including fire, fuelwood collection, illegal logging of natural forests and plantation forestry, invasive species and potential mining (Bayliss et al. 2007).
