Description complète des menacesExpert
The major threats to this taxon include predation and habitat degradation by non-native animals, particularly feral pigs (Sus domesticus), goats (Capra hircus), and deer (Axis axis), which degrade the habitat and harm the plants through predation, trampling, and rooting for food. Invasive alien plants also threaten the species by altering its habitat and competing with it for moisture, nutrients, light, and space. Rats (Rattus rattus) pose a threat to the species through predation of its plant parts and fruits. In addition, the taxon is threatened by landslides and extreme storm events. Fortini et al (2013) characterized this taxon as extremely vulnerable to climate change (vulnerability index 0.885).

Mesures de conservation recommandéesExpert
The taxon is not on the U.S. Endangered Species List or the State of Hawaiʻi Endangered Species List. Ex situ cultivation and propagule storage has not yet occurred, but it is present in botanic garden collections. Further research is needed on general ecology; life history; population size, distribution, and trends; population genetics; and threats.
