Anisomeridium biforme

Unknown

Overview

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

Anisomeridium biforme faces severe threats from air pollution and acid rain, which directly damage its sensitive lichen thallus and disrupt the delicate chemical balance required for photosynthesis. Urban development and industrial activities have eliminated many of its traditional substrates, particularly old stone walls and historic buildings that provided stable microhabitats. Climate change compounds these pressures by altering moisture regimes and temperature patterns that this slow-growing lichen depends upon for survival.

Threat summary

Habitat

This crustose lichen grows exclusively on calcareous stone surfaces, particularly old mortar joints, limestone walls, and historic masonry in urban and semi-urban environments. It requires stable, slightly alkaline substrates with consistent moisture levels and is typically found on north-facing walls that receive indirect light.

Frequently asked questions

Why is stinzenkorst classified as Endangered?
stinzenkorst 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. Anisomeridium biforme faces severe threats from air pollution and acid rain, which directly damage its sensitive lichen thallus and disrupt the delicate chemical balance required for photosynthesis. Urban development and industrial activities have eliminated many of its traditional substrates, particularly old stone walls and historic buildings that provided stable microhabitats. Climate change compounds these pressures by altering moisture regimes and temperature patterns that this slow-growing lichen depends upon for survival.
Where does stinzenkorst live?
stinzenkorst occurs in Argentina, Australia, Austria, Bahamas, Belgium, and Bermuda (plus 48 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 stinzenkorst?
The main threats to stinzenkorst 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.
