Description complète des menacesExpert
The major threats to this taxon include direct competition by invasive non-native plant species, and predation and habitat degradation by non-native animals, particularly feral pigs and goats, which degrade the habitat and harm the plants through predation, trampling, and rooting for food. Alien plants also threaten the species by altering its habitat and competing with it for moisture, nutrients, light, and space. Rats pose a severe threat to the species through predation of its plant parts and fruits. In addition, the taxon is threatened by landslides, fire, and drought. Fortini et al. (2013) characterized this taxon as extremely vulnerable to climate change (vulnerability index [0.905, on a scale of 0 being not vulnerable to 1 being extremely vulnerable]).

Mesures de conservation recommandéesExpert
The taxon is on the U.S. Endangered Species List, and also on the State of Hawaiʻi Endangered Species List. Two of the four subpopulations occur in protected areas. It is managed and monitored by the Oʻahu Army Natural Resources 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, seed storage, and threats.
