Bidens mooreensis

Declining

Overview

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

Bidens mooreensis faces severe threats from habitat destruction due to urban development and agricultural expansion on Moorea. The species' extremely limited range makes it vulnerable to any disturbance, while invasive plant species compete for resources in its native habitat. Climate change poses additional risks through altered precipitation patterns and increased storm intensity affecting the island's fragile ecosystems.
