Kadua raiateensis

Declining

Overview

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

Kadua raiateensis faces severe threats from invasive plant species that outcompete native vegetation and alter forest structure on Raiatea. Habitat degradation from human development and agricultural expansion has reduced available suitable habitat. The species' extremely limited range makes it vulnerable to stochastic events and local extinctions from small population effects.

Threat summary
