Sloanea billardieri

Unknown

Overview

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

Sloanea billardieri faces severe threats from ongoing deforestation and habitat fragmentation across its limited range in New Caledonia's rainforests. Mining activities, particularly nickel extraction, have destroyed significant portions of its native habitat, while invasive plant species compete for resources and alter forest composition. The species' extremely restricted distribution makes it highly vulnerable to any further habitat loss or environmental changes.

Threat summary

Habitat

Sloanea billardieri is endemic to the humid rainforests of New Caledonia, typically found in dense, undisturbed primary forest areas at mid to high elevations. The species requires the specific microclimate conditions of intact rainforest canopy and is associated with the island's unique ultramafic soils.
