Water: Riparian Systems Page 1 of 4 Riparian and wetland habitat Riparian vegetation grows along a creek or river. In a riparian system the terrestrial vegetation has many interconnections with the aquatic systems. Healthy riparian systems help to maintain healthy aquatic systems. Decreases erosion: Vegetation slows water movement, allowing water to sink into the ground and decreasing erosive force. The root systems of the vegetation are like rebar in a building and stabilizes the bank decreasing erosion. Less erosion means less sediment in the creek. When there is more sediment in the creek it can make it difficult for aquatic species to see, breathe, and reproduce (silt can cover eggs and decrease O 2 to eggs).
