What's My Project?

Spruce Tree Revetments

Spruce tree revetments protect streambanks from erosion and provide increased bank stabilization. This is an excellent, relatively inexpensive and functional bank stabilization technique. Spruce trees deflect water flow away from the bank, aiding in protection from scour and erosion. They trap sediment and, over time, aid in rebuilding bank structure and establishing long-term bank stability. The tree limbs reduce water velocities; provide cover for juvenile fish and are a source of organic debris.

Spruce tree revetments are often used in combination with revegetation techniques. They provide immediate cover for fish until living plant cover is provided by the revegetation techniques.

Install spruce trees parallel to the streambank and overlap 1/3 to 1/2 of their length in a shingle fashion. The top of the tree should be oriented downstream. Care should be taken to avoid unnecessary damage to, or removal of, tree limbs. The trees are secured tightly to the bank with cable and earth anchors.

Maintain new spruce tree revetments by replacing or adding new trees. Fresh, bushy trees can usually be cabled directly in front of the original revetment.
