Bocquillonia grandidens

Declining

Overview

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

Bocquillonia grandidens faces significant pressure from habitat degradation due to 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 its specialized habitat. Invasive plant species further threaten native vegetation communities where this endemic shrub occurs.
