Leptogium cochleatum

Unknown

Overview

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

Leptogium cochleatum faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter its delicate chemical balance. Urban expansion and industrial development have eliminated many of its traditional substrates, while climate change creates increasingly unsuitable microclimatic conditions for this moisture-dependent lichen. The species' extremely slow growth rate means recovery from disturbance can take decades, making populations highly vulnerable to repeated environmental stresses.

Threat summary

Habitat

This foliose lichen grows on the bark of deciduous trees, particularly favoring smooth-barked species in humid, sheltered locations with consistent moisture levels. It typically occurs in old-growth forests, mature parklands, and undisturbed woodland edges where air quality remains relatively high.
