Description complète des menacesTexte détaillé évaluation IUCNExpert
This species has a restricted range in terms of area of occupancy (AOO of 500 km2). There are numerous uses of this palm along with other species of Metroxylon. At present there is no indication that it is unsustainably harvested, but this should be carefully monitored. There has been a reduction of undisturbed upland forest on Pohnpei and most of the island's forests have been degraded or converted, mainly as a result of the cultivation of sakau (Piper methysticum) (Zicus 2001). Any rise in sea level, extreme typhoon events and tsunami can impact on the habitat of low lying atoll systems.
