How does ground cover contribute to erosion control on slopes?

Ground cover contributes to erosion control on slopes primarily through vegetative growth. The dense root systems of ground cover plants stabilize the soil, helping to prevent it from becoming loose and susceptible to erosion caused by water runoff or wind. These plants create a mat-like structure that holds the soil in place, reducing the speed of water flow across the surface and increasing water infiltration. This not only protects the soil from being washed away but also promotes better moisture retention, which benefits the plants and the soil ecosystem. The foliage from ground covers also serves to intercept raindrops, reducing the impact on the soil and thereby minimizing soil displacement. Overall, the presence of ground cover supports a healthier environment on slopes, crucial for preventing soil erosion effectively.
