Overview

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

Cranfillia nukuhivensis faces severe threats from habitat degradation on Nuku Hiva island in the Marquesas archipelago. Invasive plant species are displacing native vegetation that this endemic species depends upon, while introduced grazing animals damage the fragile island ecosystem. The species' extremely limited range makes it particularly vulnerable to local environmental changes and stochastic events.
