Soil bioengineering is the use of living plant materials to perform an engineering function. Soil bioengineering systems can be used to stabilize steep, unstable slopes, providing a cover of vegetation that initiates the successional processes that will maintain a vegetation cover on the slope forever. The pioneering species (willows, cottonwood and red-osier dogwood) that are used to treat the problem site provide conditions that foster the establishment of other species, including conifers that will ensure a healthy vegetation cover on the slope. Soil bioengineering systems are installed mostly by hand and can be used in locations where machine access is difficult.
