What is the significance of buffer strips along waterways?

Buffer strips along waterways play a crucial role in environmental conservation and land management. The primary significance of these strips is their ability to help filter pollutants from surface runoff before they enter water bodies. This filtration process is essential in maintaining water quality and preventing contamination from agricultural inputs like fertilizers and pesticides.

Additionally, buffer strips reduce soil erosion by stabilizing soils near waterways with their root systems. This stabilization helps to prevent soil from being washed away during heavy rain events, which can lead to sediment buildup in streams and rivers, further degrading water quality and aquatic ecosystems.

While aspects like attracting wildlife for biodiversity and fulfilling federal funding requirements can be beneficial consequences of buffer strips, their most direct and significant impact is on filtering pollutants and reducing erosion. This makes the second choice the most accurate representation of the primary function of buffer strips.
