Presented by Dave Polster and SER Northwest. Soil bioengineering is the use of living plant materials to perform some engineering function. In some cases, other materials are included. Soil bioengineering systems can be used to treat steep slopes and to provide stability to unstable sites. Soil bioengineering treatments use pioneering species that initiate the natural successional processes associated with the region in which they are applied. This means that in the long run, soil bioengineering systems promote the successional movement of the ecosystem towards later successional stages. Soil bioengineering systems can be used to stabilize sites that conventional systems would cost millions of dollars to stabilize. In addition, since the soil bioengineering systems promote the natural successional development of the site, there is a long term recovery of the site that does not occur with traditional treatments. In addition unlike traditional treatments, soil bioengineering systems promote the sequestration of Carbon thus help with the current climate crisis.
