A riparian buffer is a vegetated area near a river, stream, or other water body that helps protect the water quality and ecosystem. These buffers typically consist of trees, shrubs, and grasses that absorb nutrients and pollutants from runoff, preventing them from entering the water. They also provide habitat for wildlife and help stabilize the banks, reducing erosion. In addition to improving water quality, riparian buffers play a crucial role in flood management. They can absorb excess rainwater, reducing the risk of flooding downstream. Overall, riparian buffers are essential for maintaining healthy aquatic ecosystems and supporting biodiversity.
