The method of claim 29 , further comprising filling the trench with sand or soi The method of claim 18 , further comprising filling at least one of the fiber rolls with plant materia The method of claim 18 , further comprising constructing additional soil lifts on the top or side of the fiber rolls. The method of claim 18 , further comprising installing at least one erosion control blanket, wherein the blanket comprises a biodegradable material and wherein a stake secures the blanket. The method of claim 33 , further comprising inserting a plurality of posts along at least a first fiber roll of the apparatus. 35 - 51 . (canceled) A method of installing an erosion control apparatus comprising: arranging a first fiber roll relative to a shoreline; connecting a first soil lift to the fiber roll, the first soil lift comprising a fibrous layer that contains a fill material within said soil lift, each soil lift being compacted with a compactor; inserting a plurality of anchors, each anchor coupled to the first fiber roll, the anchors having an anchor point surface area inserted at a depth, wherein each anchor passes through the first soil lift and the fibrous layer that contains the first soil lift to define an anchored first layer; and repeating the above steps to form a plurality of anchored layers, at least one fiber roll being covered by a mesh. The method of claim 52 , wherein the fiber rolls comprise high density coir fiber at a nine pound per cubic foot density. The method of claim 53 , wherein the fiber rolls comprise low density coir fiber at a seven pound per cubic foot density. The method of claim 52 , wherein the anchors comprise duckbill anchors spaced at intervals across each fiber roll, each anchor including a tendon connected to an anchor point surface sized to support an overlying cone of material, each anchor including a rod or cable that extends in an orthogonal direction to a plane extending through a plurality of fiber rolls, or extends at an angle within 30 degrees of the orthogonal direction. The method of claim 55 , wherein at least one interval has a length in a range from 24 inches to 30 inches. The method of claim 52 , wherein the anchors are inserted at a depth of at least 42 inches below a slope surface of the apparatus. The method of claim 52 , wherein each anchor provides at least 3,000 pounds of holding force at an insertion point of the anchor, each anchor comprising a cable coupled to an anchor point having a surface area.
