Phaeographis leucocheila

Unknown

Overview

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

Phaeographis leucocheila faces severe threats from deforestation and habitat fragmentation in its limited range. As a lichen species dependent on specific host trees and microclimate conditions, it is particularly vulnerable to forest clearing for agriculture and urban development. The species' extremely restricted distribution makes any habitat loss potentially catastrophic for population viability.

Threat summary

Habitat

This critically endangered lichen species inhabits humid tropical forests, growing as an epiphyte on the bark of specific host trees. It requires stable microclimate conditions with consistent moisture levels and filtered light typical of undisturbed forest canopies.
