Many occurrences of this plant species are spread throughout the Hawaiian islands but the total population has declined by 10% in the last ten years. There is estimated by around a couple thousand individuals growing in its native range (Bruegmann 2003).
The main ecological threat to this taxon is habitat fragmentation from coastal development, urban sprawl, and ranching (Bruegmann 2003). Its survival is also threatened by unmanaged fires, predation and trampling by ungulates, and direct competition with invasive plant species (NatureServe 2016).
