Phyllanthus amieuensis

Declining

Overview

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

Phyllanthus amieuensis faces significant 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 alter soil chemistry. Invasive plant species further threaten native vegetation communities where this endemic shrub occurs.

Threat summary

Habitat

This endemic New Caledonian species occurs in maquis shrubland and low forest on ultramafic soils, typically at elevations between 200-800 meters. It is associated with serpentine substrates that support specialized plant communities adapted to high levels of heavy metals.
