Hernandia nukuhivensis

Declining

Overview

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

Hernandia nukuhivensis faces severe pressure from invasive plant species that compete for resources and alter forest composition on Nuku Hiva. Habitat degradation from introduced ungulates, particularly feral pigs and goats, damages the understory and prevents natural regeneration. The species' extremely limited range makes it vulnerable to stochastic events, while human activities including agriculture and development continue to fragment its remaining forest habitat.
