Bidens raiateensis

Declining

Overview

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

Bidens raiateensis faces severe pressure from invasive plant species that outcompete this endemic daisy for resources and habitat space on Raiatea. Urban development and agricultural expansion continue to fragment and destroy the limited montane forest areas where this species naturally occurs. The small population size makes the species particularly vulnerable to stochastic events and genetic bottlenecks that could drive it toward extinction.

Threat summary

Habitat

This endemic species inhabits montane forests and forest edges on the island of Raiatea in French Polynesia. It typically grows in humid, shaded areas within native forest communities at higher elevations.
