Description complète des menacesExpert
The major threats to this taxon include direct competition by invasive non-native plant species, as well as predation and habitat degradation by non-native animals. Alien plants threaten the species by altering its habitat and competing with it for moisture, nutrients, light, and space. Particularly feral pigs (Sus domesticus) degrade the habitat and harm the plants through predation, trampling, and rooting for food. Rats (Rattus rattus) pose a threat to the species through predation of its plant parts and fruits.

Habitats préférentiels (classification IUCN)

  • 1_6Forest - Subtropical/Tropical Moist Lowland
Mesures de conservation recommandéesExpert
The taxon is not on the U.S. Endangered Species List. The single subpopulation does not occur in a protected area, but it is managed and monitored by the Hawaiʻi State Division of Forestry and Wildlife and the Hawai’i Plant Extinction Prevention Program. Ex situ cultivation and propagule storage is also ongoing. Outplantings have occurred, but have not yet produced viable offspring. Further research is needed on general ecology, life history, population size, distribution, and trends; population genetics, and threats.
