Austrobuxus cracens

Unknown

Overview

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

Austrobuxus cracens faces significant pressure from habitat degradation due to mining activities and urban development within its limited range in New Caledonia. The species' restricted distribution on ultramafic soils makes it particularly vulnerable to localized disturbances, as entire populations can be eliminated by single development projects. Climate change poses an additional threat through altered precipitation patterns that could affect the specialized soil conditions this endemic shrub requires.

Threat summary

Habitat

This endemic New Caledonian shrub is restricted to ultramafic soils in maquis shrubland and low forest formations. It typically occurs at elevations between 200-800 meters on serpentine-derived substrates that are characteristic of New Caledonia's unique geological formations.
