STEEP SLOPE STABILIZATION
Restoration of landslides and unstable
slopes can provide significant challenges. Steep slopes,
low soil fertility, unstable soils, compacted tills,
flowing silts, and other adverse conditions are typical
of many forest landslides. Successional reclamation
(Polster, 1989) and soil bioengineering (Schiechtl,
1980) can be used to provide a self-sustaining vegetation
cover on many forest landslides and unstable slopes.
Soil bioengineering or biotechnical slope stabilization
is the use of living plant materials to perform some
engineering functions, whether it be simple erosion
control with grass and legume seeding or more complex
slope stabilization with live cuttings and other plants.
These techniques can be used in conjunction with conventional
engineering.
