Description complète des menacesTexte détaillé évaluation IUCNExpert
The habitat 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. Many of the sites formerly supporting this species have been cleared or are now surrounded by clearings and it is not certain that the populations survive. The species may be vulnerable to over-collection.
