Overview

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

Purple-fringed Liverwort faces severe decline due to widespread drainage and modification of its wetland habitats across Europe and North America. Agricultural intensification has eliminated many shallow ponds and temporary pools where this species historically thrived. Water pollution from agricultural runoff and urban development further degrades remaining suitable habitats, while climate change threatens the delicate hydrological balance required for its survival.

Threat summary

Habitat
