Kadua nukuhivensis

Declining

Overview

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

Kadua nukuhivensis faces severe threats from invasive plant species that outcompete native vegetation and alter forest composition on Nuku Hiva. Habitat degradation from introduced ungulates, particularly feral pigs and goats, has damaged the understory vegetation where this endemic coffee family species grows. The species' extremely restricted range on a single island makes it highly vulnerable to stochastic events and ongoing environmental changes.

Threat summary
