Wetlands help prevent erosion in 2 ways:

     1)  Wetland plants serve as a physical barrier by taking the punishment of the waves crashing into shore or the water running down a hill.

     2)  Wetland plants bind and lock down the soil with their roots, which criss-cross underground throughout the soil. Because of this, the soil is more stable and less likely to be carried away by waves or water running down a hill.
