Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Spotted Bladderwort faces severe threats from habitat degradation and loss of suitable aquatic environments. Pollution, eutrophication, and drainage of wetlands for development have significantly reduced available habitat, while climate change alters water chemistry and temperature regimes essential for this specialized carnivorous plant.
Key Facts
Habitat & Distribution
Shallow, acidic to neutral freshwater environments including ponds, lakes, slow-moving streams, and bog pools, typically in areas with soft substrates and low nutrient levels. The species requires specific water chemistry conditions and is often found in association with other aquatic vegetation in temperate wetland systems.
