Acalypha raivavensis

Declining

Overview

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

Acalypha raivavensis faces severe threats from habitat destruction on its native island of Raivavae in French Polynesia. The species' extremely limited range makes it vulnerable to invasive plant species that compete for resources and alter native ecosystem dynamics. Human activities including agriculture and development have reduced suitable habitat, while the small population size increases extinction risk from stochastic events.
