Macaranga raivavaeensis

Declining

Overview

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

Macaranga raivavaeensis faces severe threats from its extremely restricted range on Raivavae Island in French Polynesia, where the entire population is confined to a single location. The species is critically endangered due to ongoing habitat degradation from invasive plant species that compete for resources and alter the native forest ecosystem. Human activities including land conversion and infrastructure development continue to fragment and reduce the already minimal remaining habitat.

Threat summary

Habitat

This endemic tree species inhabits the remaining native forests of Raivavae Island in the Austral Islands of French Polynesia. It occurs in montane forest ecosystems at higher elevations where native vegetation persists despite widespread habitat modification across the island.
