Overview

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

Small Sweet-grass faces severe decline due to wetland drainage and agricultural intensification across its European range. The species is particularly vulnerable to water level fluctuations and eutrophication from agricultural runoff, which alters the nutrient-poor conditions it requires. Urban development and infrastructure projects continue to fragment and destroy remaining suitable habitats.

Threat summary

Habitat
