Cyclophyllum letocartiorum

Declining

Overview

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

Cyclophyllum letocartiorum faces severe pressure from deforestation and agricultural expansion across its limited range in New Caledonia's humid forests. Mining activities, particularly nickel extraction, have destroyed significant portions of its specialized habitat on ultramafic soils. The species' extremely restricted distribution makes it highly vulnerable to habitat fragmentation, while invasive plant species compete for resources in its native forest understory.

Threat summary

Habitat

This endemic New Caledonian species inhabits humid montane forests on ultramafic soils, typically found in the understory of dense rainforest communities. It occurs at elevations between 400-1000 meters in areas with high rainfall and specialized mineral-rich substrates characteristic of New Caledonia's unique geological formations.
