Ecosystem function can be defined as all of the processes necessary to preserve and create goods or services valued by humans. Healthy functioning riparian zones:
Improves the natural and beneficial functions of the floodplain
Prevents stream bank erosion
Filters storm runoff, removing pollutants before they reach the creek
Provides habitat and food for a diverse group of animals
Provides shade that cools air and water temperatures
Creates a greenbelt forest with diverse tree and plant communities for outdoor enthusiasts
