Weinmannia rapensis

Declining

Overview

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

Weinmannia rapensis faces severe pressure from invasive plant species that compete for resources and alter forest composition on Rapa Iti. The species' extremely limited range makes it vulnerable to habitat degradation from introduced ungulates and human activities. Climate change poses an additional threat through potential shifts in precipitation patterns and temperature regimes that could affect the cloud forest conditions this endemic tree requires.
