Overview

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

Intermediate Hook-moss faces severe pressure from habitat degradation caused by drainage and agricultural conversion of its wetland environments. Climate change poses an additional threat through altered precipitation patterns and increased temperatures that can dry out the moist conditions this species requires. Water pollution from agricultural runoff and urban development further compromises the quality of remaining suitable habitats.

Threat summary
