11、of woody plant species(for example,willow,dogwood,poplar,etc.)that are formed into linearbundles.These bundles are installed in shallow trenches,secured in the trench with wood stakes,then backfilled withenough soil to leave a small portion on top of the branch bundleexposed.Live fascines assist to
12、control erosion,encouragevegetative top growth establishment and rooting for shallowsoil stabilization.4.Significance and Use4.1 Live fascines are used to provide erosion and sedimen-tation control by increasing infiltration,slowing or redirectingrunoff,and trapping seed and sediments.The method pro
