Abstract: Live fascines (LF) and inert fascines (IF) are sausage-shaped bundle structures made from cuttings of living woody plant material. In the LF, the cut branches are expected to grow producing roots and top growth, (performing additional soil reinforcement via the roots and surface protection via the top growth). The LF is used from the baseflow elevation and up along the face of an eroded streambank, acting principally to protect the bank toe and bank face. They are also useful over the crown to improve erosion control, infiltration, and other riparian zone functions. The IF is not intended to grow, but can be used to protect the toe of the streambank while other vegetation becomes established. The LF and IF can also be configured to act as current deflectors and pole drains that collect and transport water. Both have the potential to accumulate sediment. LF and IF benefit fisheries habitat by providing food and cover when they are used in close proximity to the edge of the stream. Stone used at the base of the LF or IF provides substrate for an array of aquatic organisms. Some of these organisms adapt to living on and within the rocks while others utilize the leaves and stems for habitat or as food. LF or IF can improve water quality and aesthetics. Plants within the LF or IF can be selected to provide color, texture, and other attributes that add a pleasant, natural landscape appearance. Plants behind or within the IF bundle, especially emergent aquatic plants that invade and establish over time, such as bulrush (Scirpus spp.) and sedges (Carex spp), will assimilate contaminants within the water column, and reduce non-point pollution by intercepting sediment and attached pollutants coming into the stream from flow and overbank areas.
