Astelia rapensis

Declining

Overview

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

Astelia rapensis faces severe threats from invasive plant species that compete for resources and alter its native habitat structure on Rapa Iti. The species' extremely limited range makes it vulnerable to stochastic events, while introduced herbivores may damage individual plants and prevent successful reproduction. Climate change poses additional risks through altered precipitation patterns that could affect the moisture-dependent highland ecosystems where this endemic plant survives.
Threat summary

Habitat

Astelia rapensis is endemic to the montane cloud forests and high-elevation shrublands of Rapa Iti in the Austral Islands, French Polynesia. This species typically grows in moist, cool conditions at elevations above 400 meters, where it benefits from frequent cloud cover and high humidity levels characteristic of these isolated Pacific island peaks.
