Geissois superba
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Geissois superba faces significant pressure from habitat degradation due to mining activities and agricultural expansion in New Caledonia's ultramafic soils. The species' restricted range on nickel-rich substrates makes it particularly vulnerable to the island's extensive mining operations, which directly destroy its specialized habitat. Forest fragmentation from human development further isolates remaining populations, reducing genetic diversity and limiting natural regeneration.
Habitat
Geissois superba is endemic to New Caledonia's ultramafic soils, particularly thriving in humid forests on nickel-rich serpentine substrates. The species typically occurs in montane rainforest environments between 200-1000 meters elevation, where it grows as an understory to mid-canopy tree in areas with high rainfall and well-drained metalliferous soils.
