Geissois bradfordii

Unknown

Overview

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

Geissois bradfordii faces severe pressure from mining activities and infrastructure development across its limited range in New Caledonia's ultramafic soils. The species' restriction to specific geological substrates makes it particularly vulnerable to habitat fragmentation, as suitable sites become increasingly isolated. Fire regimes and invasive plant species further degrade remaining habitat patches, while the small population size increases extinction risk from stochastic events.

Threat summary

Habitat

This endemic New Caledonian species occurs exclusively on ultramafic soils in shrubland and low forest formations. It is restricted to specific geological substrates that support unique plant communities adapted to high metal concentrations and nutrient-poor conditions.

Frequently asked questions

Why is Geissois bradfordii classified as Endangered?
Geissois bradfordii is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Geissois bradfordii faces severe pressure from mining activities and infrastructure development across its limited range in New Caledonia's ultramafic soils. The species' restriction to specific geological substrates makes it particularly vulnerable to habitat fragmentation, as suitable sites become increasingly isolated. Fire regimes and invasive plant species further degrade remaining habitat patches, while the small population size increases extinction risk from stochastic events.
Where does Geissois bradfordii live?
Geissois bradfordii occurs in New Caledonia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Geissois bradfordii?
The main threats to Geissois bradfordii are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
