Kadua tahuatensis

Stable

Overview

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

Kadua tahuatensis faces severe threats from invasive plant species that outcompete native vegetation and alter ecosystem dynamics on Tahuata Island. The species' extremely limited range makes it vulnerable to stochastic events, while introduced ungulates damage native forest understory where this endemic coffee family plant grows. Climate change poses additional risks through altered precipitation patterns affecting the island's montane forest ecosystems.

Threat summary

Habitat

This endemic species occurs in montane mesic forests on Tahuata Island in the Marquesas Islands of French Polynesia. It grows in native forest understory at elevations where moisture levels support diverse endemic plant communities.
