Overview

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

Spring hook moss faces severe decline due to habitat degradation from agricultural intensification and drainage of wetland areas where it grows. Climate change poses an additional threat through altered precipitation patterns and increased drought frequency, which directly impacts the moisture-dependent environments this species requires. Water pollution from agricultural runoff and urban development further compromises the quality of its specialized spring and seepage habitats.

Threat summary

Habitat

Spring hook moss inhabits mineral-rich springs, seepages, and wet calcareous soils in temperate regions. It typically grows in areas with consistent moisture and mineral-rich water flow, often found in association with other specialized bryophytes in spring-fed wetland systems.
