Hillslope with multiple techniques used together
Biotechnical stabilization and soil bioengineering are unconventional by North American standards, but are widely used elsewhere. Whether or not such techniques are appropriate in any given situation is determined by: the site, the objectives, vegetation, and costs.
Typically in North America, these techniques have been used either in:
Comparatively high labour costs with the projects are compensated for by other factors such as use of local (inexpensive) material, and low maintenance.

Given the large number of possibilities, it can be a challenge to determine what technique (or combination of techniques) is best suited to a specific circumstance. The following tables come from a binational conference sponsored by the Greater Detroit American Heritage River Initiative and partners. As a result of the conference, a website: Best Management Practices for Soft Engineering of Shorelines, was developed. These include some but not all of the techniques discussed previously, and several not considered here.
