État de la populationTexte officiel évaluation IUCNExpert
This species apparently occurs in large, extensive populations where it grows. There is no information on population trends, but ongoing habitat destruction and degradation in Myanmar would suggest that it is likely to be declining.

Description complète des menacesTexte détaillé évaluation IUCNExpert
None of the known subpopulations are known to be directly threatened, however, most are likely to be threatened by forest clearance or by the secondary effects of this activity, such as increased turbidity and water pollution. Some subpopulations are also threatened by urbanisation and development. It must be extremely vulnerable to deforestation resulting in flashier flows, increased turbidity and reduced humidity along water courses.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
There is no conservation action specifically in place for this species. None of the populations in Kachin State are in protected areas. There is a need to survey more wetlands in the region to try to establish with some precision the limits of the distribution of this species. This should be combined with assessment of the level of threat to habitats and sites supporting this species.
