Side-fruited Crisp-moss

Pleurochaete squarrosa

Unknown

Overview

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

Side-fruited Crisp-moss faces significant pressure from habitat degradation due to agricultural intensification and urban development across its European range. The species is particularly vulnerable to changes in soil chemistry and moisture levels caused by nitrogen deposition from agricultural runoff and air pollution. Climate change poses an additional threat through altered precipitation patterns that affect the delicate moisture balance required for this bryophyte's survival.

Threat summary

Habitat

Side-fruited Crisp-moss typically grows on calcareous soils in open grasslands, chalk downs, and limestone pavements across Europe. The species favors well-drained, nutrient-poor soils with high pH levels and requires specific moisture conditions found in traditional extensive grazing systems.
