Description complète des menacesTexte détaillé évaluation IUCNExpert
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. All known populations below approximately 80 m altitude (half of known locations), as well as some above this altitude are in areas either which have already been cleared or which are being cleared of forest.
