Riparian zones are the areas of land adjacent to rivers, streams, and other bodies of water. These zones play a crucial role in maintaining the health of aquatic ecosystems by providing habitat for various plants and animals. They help filter pollutants from runoff, stabilize banks, and reduce erosion, which contributes to cleaner water. Additionally, riparian zones support biodiversity by offering food and shelter for wildlife. They often contain a mix of vegetation, including trees, shrubs, and grasses, which can vary depending on the climate and geography. Protecting these areas is essential for preserving ecosystem health and promoting water quality.
