Trimenia nukuhivensis

Declining

Overview

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

Trimenia nukuhivensis faces severe threats from habitat degradation on Nuku Hiva island in the Marquesas archipelago. The species' limited range makes it extremely vulnerable to invasive plant species that alter native forest composition and structure. Feral ungulates, particularly pigs and goats, cause significant damage to the understory vegetation where this endemic species occurs, while introduced rats may impact seed dispersal and regeneration processes.
