Cyrtandra tohiveaensis

Declining

Overview

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

Cyrtandra tohiveaensis faces severe threats from habitat degradation in its restricted montane forest range on Nuku Hiva in the Marquesas Islands. Invasive plant species are displacing native vegetation and altering forest composition, while feral ungulates damage the understory habitat critical for this endemic shrub. The species' extremely limited distribution makes it particularly vulnerable to stochastic events and ongoing environmental changes.
