Description complète des menacesTexte détaillé évaluation IUCNExpert
This species occurs in hilly areas which remain relatively inaccessible, which may provide some security. However, the area has no formal protection and is vulnerable to the factors which affect flowing water systems in the region, notably destruction and clearance of forest with the consequent changes to hydrology, sediment load and water quality. One of the subpopulations is adjacent to an area which has been cleared for agriculture and must be considered extremely threatened. It is also threatened by collection from the wild for the plant trade.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
Whilst this species does not occur in a formally protected area, it occurs in an area which is relatively inaccessible, which may afford it some protection, although lowland habitats within a few kilometres have been cleared for agriculture. There is a need for further surveys to clarify the true extent and size of existing populations. If no more subpopulations are found outside the immediate area containing the known subpopulations, efforts should be made to establish some level of protection for the known populations.
