<br />Willow Clump Revetment <br /> <br />When meander erosion is oc,:urring, clumps of live willows can be relocated <br />from local areas which hav,! excess willows to protect either straight or <br />meander type erosion. <br /> <br />The clumps can be dug and :ransported using a front end loader or backhoe <br />tractor and placed directl:' into the stream bottom against the bank, Willows <br />should normally be placed~n locations where they receive perennial water/ <br />mo is ture. <br /> <br />The clumps should be place,l so stream flow can not get behind or between <br />clumps. On meanders, clump protection such as steel posts with woven wire <br />fence should be installed 1;0 ensure the clumps stay in place until well rooted <br />(one year's protection is ,.dequate). This protection may also be necessary on <br />straight channel sections l.f stream flows are high enough to endanger washing <br />out of freshly placed clumps. The woven wire should be installed high enough <br />up bank on the ends to ensure the clumps and fence are not washed out the <br />firs t season. The banks cOIn then be s loped to 1. 5 to 1 or grea ter s lope and <br />seeded with an adapted gra,.s or local clumps of sod to speed up the total bank <br />rehabilitation. This may fLot be necessary as the clump protected banks will <br />slough and revegetate natul'8lly, but will help in weed control. <br /> <br />Maintenance requirements fe,r this practice include replacing sections that <br />wash out and reseeding tho.,e sections that do not establish adequate grass <br />stands. <br /> <br />. <br /> <br />RR <br />
