Grynet kvistlav

Hypogymnia farinacea

Unknown

Overview

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

Hypogymnia farinacea faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter bark chemistry and disrupt lichen symbiosis. Habitat fragmentation from forestry practices reduces suitable old-growth substrates, while climate change creates increasingly unsuitable moisture and temperature conditions for this sensitive epiphytic species.

Threat summary

Habitat

This epiphytic lichen grows on the bark of mature deciduous and coniferous trees in old-growth and semi-natural forests, particularly favoring areas with high humidity and clean air. It typically occurs in montane and boreal forest ecosystems where atmospheric pollution levels remain relatively low.
