Justification of Red List category

This species has an extremely small range and population size, restricted to a single subpopulation on the southwestern slope of Mauna Kea where its survival is tightly linked to the availability of m?mane seed pods. Annual transect surveys indicate that the species is declining at a rate exceeding 50% in three generations, driven primarily by prolonged drought and habitat degradation by introduced ungulates and invasive plants. The species is restricted to a single location where all individuals present are highly vulnerable to fire. It is therefore assessed as Critically Endangered.
