Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Potamogeton angustifolius faces severe threats from habitat degradation and loss of suitable aquatic environments. Water pollution, eutrophication from agricultural runoff, and drainage of wetlands have significantly reduced available habitat, while climate change and altered hydrological regimes further threaten remaining populations.
Key Facts
Habitat & Distribution
This aquatic plant inhabits shallow freshwater lakes, ponds, slow-flowing rivers, and permanent wetlands with muddy or sandy substrates. It typically grows in nutrient-poor to moderately nutrient-rich waters at depths of 0.5-3 meters, often forming submerged beds in clear, well-oxygenated aquatic environments.
