Overview

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

The Irish Rock-bristle faces severe habitat degradation from quarrying activities and limestone extraction, which directly destroys the specialized calcareous rock surfaces it requires. Agricultural intensification and nutrient enrichment from fertilizer runoff alter the delicate chemical balance of its rocky substrates, making them unsuitable for colonization. Climate change poses an additional threat through altered precipitation patterns that affect the moisture regimes essential for this bryophyte's survival and reproduction.

Threat summary

Habitat

This rare moss species inhabits crevices and surfaces of calcareous rocks, particularly limestone outcrops and cliff faces in coastal and inland areas. It requires specific moisture conditions and thrives on base-rich substrates with minimal competition from other vegetation.
