The researchers studied the plants in Ansupa Lake in India to see how they affect the lake's ecosystem. They found 244 different plant species, with most being semi-aquatic. Some plants were submerged, floating, or marshy. Most of the plants were annuals, meaning they grow and die in one year. The researchers also calculated diversity indices to measure the variety of plants in the lake. They found that while the lake has a diverse range of plants, some invasive species are threatening its health. Proper management is needed to protect the lake and its plants for the benefit of people.
