lunglavsknapp

Plectocarpon lichenum

Unknown

Overview

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

Lunglavsknapp faces severe pressure from air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical balance of its substrate. Forest management practices including clear-cutting and intensive harvesting eliminate the old-growth conditions this lichen requires. Climate change compounds these threats by altering precipitation patterns and increasing temperature extremes that stress the delicate symbiotic relationship between fungal and algal components.

Threat summary

Habitat

This crustose lichen grows exclusively on the bark of old deciduous trees, particularly favoring mature beech, oak, and maple in undisturbed forest environments. It requires stable microclimatic conditions with high humidity and minimal air pollution, typically found in ancient woodlands and old-growth forest remnants.
