Oxera cauliflora
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.
Habitat
Oxera cauliflora is endemic to New Caledonia, where it inhabits ultramafic soils in shrubland and forest margins at low to moderate elevations. The species is adapted to the unique mineral-rich, serpentine-derived soils that characterize much of New Caledonia's distinctive flora.
