Overview

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

The Marsh Whorl Snail faces severe threats from wetland habitat destruction and degradation due to agricultural conversion, urban development, and drainage of marshes and fens. Climate change-induced alterations to water levels and increased frequency of extreme weather events further threaten the specialized calcareous wetland environments this species requires. Pollution from agricultural runoff and invasive plant species that alter habitat structure compound these pressures on remaining populations.

Threat summary

Habitat

Inhabits calcareous marshes, fens, wet meadows, and other alkaline wetlands with consistent moisture levels and specific vegetation communities. Requires areas with calcium-rich soils and water, typically found in sedge beds, reed swamps, and marshy grasslands.
