"Because of its tolerance of wet soils, rapid establishment and growth, and potentially extensive rooting of prostrate stems, redosier dogwood is often recommended for stream bank revegetation and erosion control. It is also a useful choice in regevetation because of its ability to shade streams and provide structural diversity for wildlife and birds.
Redosier dogwood may also be useful in the revegetation of roadside cuts and mine sites."
