Oxera macrocalyx

Unknown

Overview

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

Oxera macrocalyx faces significant pressure from habitat degradation across its limited range in New Caledonia's humid forests. Mining activities, particularly nickel extraction, pose a substantial threat to the species' forest habitat through direct destruction and associated infrastructure development. The species' restricted distribution makes it particularly vulnerable to localized disturbances, while invasive plant species compete with native vegetation and alter forest composition.

Threat summary

Habitat

Oxera macrocalyx inhabits humid forests and forest margins in New Caledonia, typically occurring in areas with well-developed canopy cover and rich understory vegetation. The species is adapted to the island's unique ultramafic soils and associated plant communities.
