Cedar tree revetments are a low cost, environmentally friendly option to address eroding streambanks. Cedar revetments use Eastern red cedar trees to serve as natural armor, providing protection along eroding riverbanks. Revetments will slow or stop erosion during the project's lifespan and reduce the likelihood of a much larger and more expensive corrective project in the future. Riverbank erosion contributes sediment and other pollutants into waterways, reduces riparian habitat, and results in property loss. Stabilizing your eroding riverbank will provide water quality benefits as well as protect your property.

Photo: Trees are limbed on one side so the trunk is seated into the riverbank. The trees are anchored at the toe-of-bank with the tops of the trees facing downstream.
