They will then be anchored lengthwise to the shoreline and joined together for a 100 foot stretch, with the root wads facing upstream. The end result of this stabilization project is exhibited on the two schematic drawings that can be viewed by clicking on the tree trunk icons that are on the Detailed Design Drawings for Zone 2. Finally, live willow cuttings will be placed in the embankment above the tree trunks, to provide further shading and habitat structure. Trunks and roots trap sediment at the toe of the bank, gradually reducing it's slope. Trunks and roots absorb energy of flowing water and reduce bank erosion.
Plantings stabilize bank soils and reduce erosion of streambank.
