Streambank Restoration
The Petsinger Streambank Restoration Site On June 28, 2006 a "hands on" workshop was held to add conifer revetments to the Petsinger Stream bank Restoration Site. Brush and tree revetments are non-sprouting shrubs or trees installed along the toe or edge of a stream bank. This treatment is sometimes referred to a Christmas Tree Revetments. The purpose of a revetment is to slow stream velocity (speed) adjacent to an eroding bank and to promote sediment deposition at the toe of the river. The revetment material does not need to sprout (most species used will not). It is generally recommended that live willows or other quickly sprouting species be planted behind the revetment to provide permanent cover. Following are photos and descriptions of what conifer revetments are and how they are installed.
Specifications and materials used for the design of the revetments at this site. The Grand Forks Air Force Base had a stand of conifer trees that need thinning and allowed the ND Forest Service and GF County SCD Watershed Coordinator onto the base to remove the trees. They transported the trees to the site prior to the workshop.
