Cyrtandra thibaultii

Declining

Overview

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

Cyrtandra thibaultii faces severe pressure from habitat degradation in its limited range within French Polynesian montane forests. Invasive plant species, particularly aggressive weeds and non-native trees, are displacing native vegetation and altering the understory conditions this endemic species requires. The species' restricted distribution makes it extremely vulnerable to localized disturbances, while climate change threatens to shift suitable habitat zones beyond the plant's ability to adapt or migrate.

Threat summary

Habitat

Cyrtandra thibaultii is endemic to the montane rainforests of French Polynesia, typically found in humid understory environments at moderate to high elevations. The species requires the specific microclimate conditions of intact native forest, including consistent moisture levels and filtered sunlight beneath the forest canopy.
