Overview

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

Staurothele areolata faces severe pressure from air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its substrate. Urban development and quarrying activities destroy the specific calcareous rock surfaces this lichen requires. Climate change poses additional stress through altered precipitation patterns and temperature fluctuations that affect the delicate moisture balance essential for this species' survival.

Threat summary

Habitat

This crustose lichen grows exclusively on calcareous rocks and limestone surfaces in exposed to semi-shaded locations. It typically occurs on vertical or overhanging rock faces in coastal areas, quarries, and natural limestone outcrops where it forms distinctive areolate crusts.
