What is the main purpose of a riparian buffer zone?

To increase land development

To protect water quality by filtering runoff

The primary function of a riparian buffer zone is to protect water quality by filtering runoff. Riparian buffer zones are vegetated areas near water bodies, such as rivers, streams, and lakes, and they play a vital role in maintaining the ecological health of these waterways. The vegetation in these zones helps to absorb excess nutrients, sediments, and pollutants from surface runoff before they reach the water. This natural filtration process is crucial because it reduces the likelihood of water quality degradation, which can occur from agricultural, urban, and industrial activities.

By acting as a barrier, riparian buffers help stabilize stream banks, reduce erosion, enhance habitat for wildlife, and contribute to the overall integrity of aquatic ecosystems. In summary, the main purpose of a riparian buffer zone centers on its role in water quality protection through the natural filtration of runoff.
