Acarospora anomala

Local name: träspricklav

Unknown

Overview

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

Träspricklav faces severe threats from air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its bark substrates. Forest management practices including clear-cutting and selective logging destroy the old-growth deciduous trees this lichen requires for survival. Climate change compounds these pressures by altering precipitation patterns and increasing temperature stress on both the lichen and its host trees.

Threat summary

Habitat

Träspricklav grows exclusively on the bark of old deciduous trees, particularly favoring mature oak, ash, and maple in well-lit forest environments. This epiphytic lichen requires stable microclimatic conditions found in undisturbed woodland areas with minimal air pollution.

Frequently asked questions

Why is träspricklav classified as Endangered?
träspricklav is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Träspricklav faces severe threats from air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its bark substrates. Forest management practices including clear-cutting and selective logging destroy the old-growth deciduous trees this lichen requires for survival. Climate change compounds these pressures by altering precipitation patterns and increasing temperature stress on both the lichen and its host trees.
Where does träspricklav live?
träspricklav occurs in Austria, Estonia, Finland, Italy, Netherlands, and Russia (plus 2 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to träspricklav?
The main threats to träspricklav are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
