<br />Ancho.ed Tree Revetment <br /> <br />Anchored trees can be used as an effective method of stream bank protection on <br />most streams. They can be used on streams with any degree of meandering. The <br />trees can be placed perpendicular or parallel to the bank. The trees should <br />be as bushy as possible. Juniper and brushy willow work well. The trees are <br />placed with the butt end of'the tree against the bank and/or upstream. The <br />trees are anchored with cable and deadmen to hold them in place. The anchors <br />are located on the bank at least la feet from the edge of the bank. The area <br />behind the trees is sometimes filled with gravel or other material. This <br />help. hold the trees in place and also provides a surface which can be <br />seeded. Even when the area behind the trees is not backfilled. some type of <br />vegetation should be establi.hed. The up.tream and down.tream end of the <br />reach must be protected to minimize the chance of water setting behind the <br />tree. and causing erosion. The most effective long-term result from this <br />practice occur. when vegetation has been established along the entire reach. <br /> <br />Maintenance requirements for this practice include repairing damaged cable or <br />anchors. Disturbed spots or scour holes behind the trees or on the ends <br />should be repaired and protected. <br /> <br />44 <br />
