Kadua rapensis

Declining

Overview

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

Kadua rapensis faces severe threats from invasive plant species that outcompete native vegetation and alter ecosystem dynamics on Rapa Iti. The species' extremely limited range makes it vulnerable to stochastic events, while habitat degradation from introduced herbivores and human activities continues to reduce suitable growing areas. Climate change poses additional risks through altered precipitation patterns and potential sea-level rise impacts on coastal populations.

Threat summary
