Archirhodomyrtus vieillardii

Declining

Overview

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

Archirhodomyrtus vieillardii faces severe pressure from mining activities and urban development across its limited range in New Caledonia. The species' restriction to ultramafic soils makes it particularly vulnerable to nickel mining operations, which directly destroy habitat and fragment remaining populations. Fire regimes altered by human activities pose an additional threat to this endemic shrub's specialized ecosystem requirements.

Threat summary

Habitat

This endemic New Caledonian shrub occurs exclusively on ultramafic soils in maquis shrubland and low forest formations. It is restricted to specific geological substrates that support unique plant communities adapted to high concentrations of heavy metals.
