Overview

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

Revolute Beard-moss faces significant pressure from habitat degradation in its specialized limestone and calcareous rock environments. Urban development and quarrying activities directly destroy the exposed rock faces and cliff habitats essential for this species' survival. Climate change poses an additional threat through altered precipitation patterns that affect the delicate moisture balance required by this bryophyte, while air pollution from industrial activities may be compromising the quality of its substrate environments.

Threat summary

Habitat

This moss species typically inhabits exposed limestone outcrops, calcareous cliffs, and rocky crevices in Mediterranean and temperate regions. It requires well-drained calcareous substrates with specific moisture conditions, often growing on vertical or near-vertical rock faces where it can access adequate light while maintaining necessary humidity levels.
