Overview

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

Kyst-bægerlav faces severe decline due to coastal habitat degradation from urban development and infrastructure expansion along Scandinavian shorelines. Rising sea levels and increased storm intensity associated with climate change threaten the species' specialized maritime cliff and dune environments. Atmospheric pollution, particularly nitrogen deposition from industrial sources, alters the delicate chemical balance of its substrate, reducing lichen growth and reproduction rates.

Threat summary

Habitat

This coastal lichen species inhabits exposed maritime cliffs, sandy dunes, and rocky shorelines along the North Atlantic coast, particularly in Norway and Denmark. It requires well-drained, calcium-rich substrates in areas with high salt spray exposure and minimal vegetation competition.
