État de la populationTexte officiel évaluation IUCNExpert
There is no information on population size or trends in this species. The subpopulation at Balai Ringin was described as involving millions of plants in 2004, but there is no information on the extent that such a population might involve only a very small number of clones. Many subpopulations are in urban areas and some are being lost to gradual habitat degradation, as well as wetland destruction.

Description complète des menacesTexte détaillé évaluation IUCNExpert
None of the sites where this variety occurs are protected and most are therefore already suffering from or threatened by the factors affecting all lowland river systems in Borneo, the primary and secondary effects of forest degradation and clearance, direct habitat destruction and pollution. Most of the sites from which it is known are in areas which have been cleared for some time and within which it is threatened by intensification of agriculture and expansion of settlements.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
There are no conservation actions specifically in place for this species. There is a need to conduct an assessment of the conservation condition of known subpopulations and to search for other extant populations in the area. There is also a need to attempt to protect known populations, both within Sekadau and in the wider area.
