Sophora rapaensis

Declining

Overview

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

Sophora rapaensis faces severe threats from its extremely restricted range on Rapa Iti island, where the entire population is confined to a single location. Invasive plant species compete directly with native vegetation, while introduced grazing animals damage seedlings and alter soil composition. The species' limited genetic diversity and small population size make it particularly vulnerable to stochastic events and environmental changes.

Threat summary

Habitat

This endemic tree species is restricted to the montane forests and shrublands of Rapa Iti island in French Polynesia. It typically grows in rocky, well-drained soils at elevations between 300-650 meters, often on steep slopes and ridge systems.
