Lesser Marshwort

Helosciadium inundatum

Unknown

Overview

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

Lesser Marshwort faces severe decline due to widespread drainage and modification of wetland habitats across its European range. Agricultural intensification has eliminated many shallow pools and marshy areas where this aquatic plant historically thrived. Water pollution from agricultural runoff and urban development further degrades remaining suitable habitats, while climate change threatens to alter the hydrological patterns essential for its seasonal growth cycle.

Threat summary

Habitat

Lesser Marshwort inhabits shallow, temporary pools, ditches, and marshy areas that experience seasonal flooding and drying cycles. It typically grows in nutrient-poor, muddy substrates in lowland wetlands, pond margins, and occasionally in rice fields across temperate Europe.
