Description complète des menacesTexte détaillé évaluation IUCNExpert
Major threats to this taxon include direct competition by invasive non-native plant species such as Clidemia hirta, Paspalum conjugatum, Paspalum urvillei, Psidium cattleianum and Pterolepis glomerata. Predation and habitat degradation by non-native animals, particularly pigs and rats, are also a major threat. This taxon is vulnerable to stochastic disturbance events such as landslides and hurricanes. In addition, Fortini et al. (2013) characterized this taxon with high expected vulnerability to climate change (vulnerability indicator 0.509).

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
The taxon is not listed as Threatened or Endangered under the U.S. Endangered Species Act nor by the State of Hawai'i. Field botanists of the National Tropical Botanical Garden (NTBG) have made seed collections over the years, several accessions of which have been propagated and occur in NTBG's Allerton and McBryde gardens on Kaua'i. Some some accessions have been deposited in NTBG's Seed Bank and Laboratory on Kaua'i, but Pritchardia seeds cannot be stored conventionally (cannot be dried and cooled).
