Vegetation refers to a ground cover that serves as soil protection from the forces of erosion. It is the most efficient method of controlling soil erosion. Maintaining existing vegetation and establishing new ones stabilizes slopes, keeps soil firm together, reduces the speed of stormwater runoff, increases surface roughness and water infiltration, traps sediments, and controls soil erosion. In addition, vegetation captures other pollutants including sediments, nutrients and other toxic chemicals, thereby ensuring water quality.
