État de la populationExpert
It occurs in a few very small and scattered subpopulations, with potentially fewer than 50 mature individuals in total.

Menaces identifiées(2 menaces classées CMP-IUCN)

  • 5_2_1
    Intentional use (species is the target)
    Ongoing
  • 7_1_1
    Increase in fire frequency/intensity
    Ongoing
Description complète des menacesExpert
Illegal collection of seedlings poses the main threat. Further fires could also impact the habitat and thus the population, although fire does not appear to significantly affect the regeneration of the species. The mountain is considered to be sacred by the local people, and given the remoteness of the area, deforestation is not a problem at present.
