Psychotria tahitensis

Unknown

Overview

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

Psychotria tahitensis faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in French Polynesia. Invasive plant species compete directly with this endemic coffee family member, altering the understory composition of its native forest habitat. The species' extremely restricted distribution makes it particularly vulnerable to stochastic events and climate-related changes affecting montane forest ecosystems.
