Using native vegetation to stabilize steep hillslopes just makes sense. On the Cottagewood site, we used a variety of bio-engineering techniques and a multitude of planting and seeding methods to establish a very functional, deep-rooted hillside prairie restoration. Here are the advantages: it looks terrific during all seasons, prairie plants send roots 10 to 12 feet into the soil, erosion in minimized, irrigation and fertilizers not needed, and the habitat value cannot be rivaled. Steep lakeshore slopes are our specialty.
