Psychotria hivaoana

Declining

Overview

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

Psychotria hivaoana faces severe threats from habitat degradation on its native island of Hiva Oa in the Marquesas Islands. The species' extremely limited range makes it vulnerable to invasive plant species that alter forest composition and compete for resources. Feral ungulates, particularly pigs and goats, damage the understory vegetation where this coffee family shrub grows, while human activities including agriculture and development continue to fragment its already restricted habitat.

Threat summary

Habitat

This endemic shrub inhabits the mesic forests and forest margins of Hiva Oa in the Marquesas Islands, typically growing in understory conditions within native vegetation communities. It occurs at mid-elevations where moisture levels support diverse endemic plant assemblages characteristic of Polynesian island ecosystems.
