Oxera cauliflora

Unknown

Overview

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

Oxera cauliflora faces significant pressure from habitat degradation due to mining activities and urban development across its limited range in New Caledonia. The species' restricted distribution on ultramafic soils makes it particularly vulnerable to localized disturbances, while invasive plant species compete for resources in its specialized habitat. Fire events, both natural and human-induced, pose additional threats to remaining populations of this endemic shrub.
