Pycnandra viridiflora

Declining

Overview

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

Pycnandra viridiflora faces severe threats from nickel mining operations across its native New Caledonian range, with open-pit extraction destroying entire populations and their specialized ultramafic substrates. Forest degradation from invasive plant species, particularly introduced shrubs and grasses, further fragments the remaining habitat patches. Fire events, both natural and human-induced, pose additional risks to this slow-growing endemic tree species with limited dispersal capacity.

Threat summary

Habitat

This endemic New Caledonian tree species inhabits ultramafic soils in humid forests and forest margins, typically occurring on serpentine substrates at elevations between 200-800 meters. It grows in specialized plant communities adapted to the high heavy metal content of these unique geological formations.

Pycnandra viridiflora faces severe threats from nickel mining operations across its native New Caledonian range, with open-pit extraction destroying entire populations and their specialized ultramafic substrates. Forest degradation from invasive plant species, particularly introduced shrubs and grasses, further fragments the remaining habitat patches. Fire events, both natural and human-induced, pose additional risks to this slow-growing endemic tree species with limited dispersal capacity.
Where does Pycnandra viridiflora live?
Pycnandra viridiflora occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Pycnandra viridiflora?
The main threats to Pycnandra viridiflora 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.
