Overview

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

Water-gladiolus faces severe threats from habitat destruction due to wetland drainage, water pollution, and agricultural conversion of its native freshwater environments. Climate change and altered hydrological regimes further threaten remaining populations, while invasive species competition reduces available habitat niches.

Threat summary

Habitat

Shallow freshwater wetlands, pond margins, slow-flowing rivers, and marshy areas with muddy or sandy substrates, typically in temperate regions. The species requires nutrient-rich waters and establishes in both natural wetlands and constructed water bodies such as canals and ditches.
