Overview

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

Water spangles faces severe threats from habitat degradation, water pollution, and competition from invasive aquatic species that can rapidly colonize and dominate freshwater ecosystems. Climate change and altered hydrological patterns further threaten the delicate balance of shallow water environments this species depends on. Conservation status may vary by region or assessment authority, but populations continue to decline due to human impacts on freshwater systems.

Threat summary

Habitat

Water spangles inhabits shallow freshwater environments including ponds, lakes, slow-moving streams, and wetlands with calm or still water surfaces. This free-floating aquatic fern typically occurs in nutrient-rich waters and can form dense mats on the water surface in suitable conditions.
