Oparanthus rapensis

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Oparanthus rapensis faces severe threats from invasive plant species that compete for limited resources on Rapa Island's restricted habitat. The species' extremely small population size and confined range make it highly vulnerable to stochastic events and genetic bottlenecks. Human activities including habitat modification and the introduction of non-native species continue to pressure the remaining populations.
