Ixora uahukaensis

Declining

Overview

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

Ixora uahukaensis faces severe threats from invasive plant species that outcompete native vegetation and alter forest composition in its restricted Marquesas Islands habitat. Habitat degradation from introduced ungulates, particularly feral pigs and goats, has damaged the understory vegetation where this endemic shrub grows. The species' extremely limited range on Ua Huka makes it highly vulnerable to stochastic events and environmental changes.

Threat summary

Habitat

This endemic shrub occurs in the native montane forests and forest margins of Ua Huka in the Marquesas Islands, French Polynesia. It grows in humid forest understory environments at elevations where native vegetation communities remain relatively intact.
