Pittosporum rapense
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pittosporum rapense faces severe threats from habitat degradation on its native Rapa Island in French Polynesia. The species is particularly vulnerable to invasive plant species that compete for resources and alter the native ecosystem structure. Grazing by introduced livestock and feral animals has further degraded the limited suitable habitat, while the species' extremely restricted range makes it highly susceptible to stochastic events and environmental changes.
Habitat
Pittosporum rapense is endemic to Rapa Island in the Austral Islands of French Polynesia, where it inhabits montane shrublands and forest margins at higher elevations. The species grows in rocky, well-drained soils on steep slopes and ridges, typically in areas with high humidity and frequent cloud cover.
