Why is protecting highly erodible land (HEL) important?

Protecting highly erodible land (HEL) is crucial because it helps to reduce water pollution stemming from sedimentation and excess nutrients. When land becomes eroded, soil and agricultural runoff can enter waterways, carrying with it not just sediment but also fertilizers and pesticides used in farming. This excess nutrient runoff, particularly nitrogen and phosphorus, can lead to serious water quality issues, such as algal blooms and dead zones, which harm aquatic ecosystems and can be detrimental to drinking water supplies.

By implementing conservation practices on HEL, such as planting cover crops or creating contour strips, farmers can minimize erosion, thus protecting both the soil health and the surrounding water bodies. These practices enhance the resilience of the landscape while contributing to overall environmental quality and sustainability of water resources.
