Description complète des menacesExpert
The habitats and sites where this species occurs are threatened by factors which affect all plants occurring in flowing water bodies in the region, notably forest clearance, urbanisation, agricultural intensification and the secondary effects of these factors, particularly increased turbidity, pollution and casual habitat degradation.

Mesures de conservation recommandéesExpert
Habitat in Sumatra, Johor and other smaller islands appears to be highly threatened. There are no conservation actions in place specifically for this species. It is known to occur in Gunung Mulu National Park in Sarawak. It would be useful to establish an up-to-date assessment of the conservation status of known populations.
