Justification of Red List category
This species is classified as Vulnerable since it has a very small range, confined to the top of an active volcano. The population is suspected to have declined since 1985 owing to a reduction in the Area of Occupancy as a result of volcanic activity, however the extent of habitat is expected to recover through natural regeneration so the species is not suspected to be undergoing a continuing decline. Nevertheless, the limited range and small population of this species render it extremely susceptible to future threats, most notably, a serious eruption. In such a case the species may warrant uplisting to Critically Endangered.
