“Riparian restoration [is] the reestablishment of riparian functions and related physical, chemical, and biological linkages between terrestrial and aquatic ecosystems; it is the repairing of the diversity and dynamics of indigenous ecosys- tems degraded by human impacts. Its goal is to ensure that the dynamics of natural ecosystem processes are again operating efficiently so that both ecosystem structure and functions can be recovered and sus- tained” (Beschta and others 2000)
