The establishment of an extensive, reinforcing root network plays an important role in enhancing slope stability. The use of deep rooting, pioneering shrubs in stabilization projects has been effectively used in British Columbia since the early 1980's. Although willow and cottonwood are the more commonly used woody species, a wide variety of trees and shrubs have been used as either bare-root or container stock. Successful projects depend on:
- proper design of the planting system,
- selection and propagation of appropriate plant material,
- correct timing of installation.
