Declining

Overview

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

Cyrtandra tahuatensis faces severe threats from habitat degradation on its native island of Tahiti in French Polynesia. The species is particularly vulnerable to invasive plant species that alter the understory composition of its native forest habitat, reducing suitable growing conditions. Ongoing development pressure and agricultural expansion continue to fragment the remaining forest patches where this endemic plant survives.
