| Abstract: | The live stake (LS) and joint planting (JP) soil bioengineering systems are units fabricated from live, woody plant material branches. Over time, the LS’s are effective for erosion control and the JP system provides reinforcement to slopes upon which rock has been placed. The LS and JP live cut branches are expected to grow roots and top growth, with the roots providing additional soil reinforcement and surface cover providing protection from runoff and streamflow. The LS and JP units are used from the baseflow elevation up the face of the streambank, acting principally to protect the bank toe and face. In the case of the JP’s, the root soil reinforcement serves to augment bank protection. The LS’s and JP’s are also useful to improve erosion control and infiltration and support the riparian zone. Once top growth has developed, both systems have the potential to accumulate sediment (Figures 1-7). The LS and JP may improve aquatic habitat by providing food and cover in the riparian zone and over the water when they are used in close proximity to the edge of the stream. Stone used at the base of the LS or with JP produces substrates suited for an array of aquatic organisms. Some of these organisms adapt to living on and within the rocks and some attach to the leaves and stems. The leaves and stems may also become food for shredders. Species for LS and JP systems can be selected to provide color, texture, and other attributes that add a pleasant, natural landscape appearance. Such plants for LS and JP systems include willow (Salix spp.), which tends to be the best from an adventitious rooting perspective and is normally an excellent choice. However other species such as poplar (Populus spp.), Viburnum spp., Hibiscus spp., shrub dogwood (Cornus spp.) and buttonbush (Cephalanthus), also work well. After establishment, the LS and JP systems can reduce non-point pollution by intercepting sediment and attached pollutants that otherwise enter the stream from overbank flow areas. |
