A riparian zone is the interface between land and a river or stream. This area is crucial for maintaining the health of aquatic ecosystems, as it provides habitat for various plants and animals. Riparian zones help filter pollutants from runoff, stabilize banks, and reduce erosion, making them vital for water quality. These zones are typically characterized by lush vegetation, including trees, shrubs, and grasses. The presence of this vegetation supports biodiversity and offers food and shelter for wildlife. Additionally, riparian zones play a significant role in flood management by absorbing excess water during heavy rainfall events.
