Overview

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

Gyttrad kalkspricklav faces severe pressure from air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemistry of its calcium-rich substrates. Urban development and quarrying activities directly destroy the limestone outcrops and calcareous rocks essential for this lichen's survival. Climate change compounds these threats by altering precipitation patterns and increasing temperature extremes that stress this slow-growing species.

Threat summary

Habitat

This crustose lichen grows exclusively on calcium-rich substrates including limestone outcrops, calcareous rocks, and mortar of old stone buildings. It typically occurs in semi-natural environments with good air quality, often in upland areas where calcareous bedrock is exposed.
