Cedar Tree Revetments are a riverbank stabilization method that uses Eastern red cedar trees anchored along an eroding stream bank. The trees serve as soft, natural armor and greatly slow the current along the eroding bank. This decreases erosion and allows silt and sand to be deposited. The deposited material forms a good bed in which the seeds of riverbank plants such as sedges can sprout and grow. By the time the revetment trees have decayed, the bank should be stabilized by the roots of new growth and accumulated sediment. Cedar tree are suitable for mild to moderate erosion. For vertical banks more than 5 ft tall or areas of high water velocity, revetment may be inadequate.
