Overview

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

Klosterlav faces severe pressure from air pollution and acid rain, which alter the chemical composition of its limestone substrates and reduce lichen diversity in its specialized monastic wall habitats. Urban development and restoration activities at historic monastery sites frequently destroy the specific microhabitats this species requires, while climate change is shifting precipitation patterns that affect the delicate moisture balance needed for its survival.

Threat summary

Habitat

Klosterlav is endemic to limestone walls and mortared surfaces of medieval monasteries and churches across central Europe, particularly thriving on north-facing walls with consistent moisture levels. This highly specialized lichen requires the specific chemical composition of traditional lime mortars and the unique microclimate created by monastic architecture.
