Atractocarpus tahitiensis

Unknown

Overview

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

Atractocarpus tahitiensis faces severe threats from habitat destruction driven by urban development and agricultural expansion across its limited range in French Polynesia. Invasive plant species compete aggressively with native vegetation, altering forest composition and reducing suitable habitat. The species' extremely restricted distribution makes it particularly vulnerable to stochastic events and human disturbances that could eliminate entire populations.
