Priyanka Jamwal Bangalore Mirror |  July 13, 2025 “Shoreline vegetation creates a delicate balance in a lake ecosystem. If removed, cyanobacteria are exposed to a large amount of sunlight, which increases their capability to multiply exponentially. After the bloom, the bacteria also die at the end of the life cycle, forming a layer of organic matter at the bottom of the lake. This organic matter starts decaying, which causes a further dip in oxygen level,” said Priyanka Jamwal senior fellow at ATREE.
