Coprosma fatuhivaensis

Stable

Overview

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

Coprosma fatuhivaensis faces severe threats from invasive plant species that outcompete native vegetation and alter ecosystem dynamics on Fatu Hiva. Habitat degradation from introduced ungulates, particularly goats and pigs, has damaged the understory vegetation where this endemic shrub grows. The species' extremely restricted range on a single island makes it highly vulnerable to stochastic events and environmental changes.

Threat summary

Habitat

This endemic shrub occurs in the montane cloud forests and humid valleys of Fatu Hiva in the Marquesas Islands. It grows in understory vegetation within native forest remnants at elevations where moisture levels remain consistently high.
