Abstract

In terms of ecological function in river systems, riparian vegetation, land use and habitat structure are three of the most important factors contributing to success of salmonid fisheries. First and foremost is riparian vegetation or the plant life bordering the stream channel. Riparian vegetation provides a myriad of benefits including cooling and regulation of water temperature, stabilization of banks, and reduced suspended sediment load. Second is land use. A large number of streams have been degraded by livestock grazing too closely to stream banks. Unsustainable grazing practices in close proximity to river channels can degrade riparian vegetation and dissuade regrowth. Healthy riparian vegetation is crucial for waters suitable for fish. The third consideration is sustaining fish habitat within the channel through the recruitment of large woody debris (LWD). The addition of tree fall to a river channel provides crucial features for fish habitat. LWD creates hydraulic complexity by providing low-energy refugia for fish to forage, as well as providing physical shelter from predators. Both of these benefits facilitate anadromous fish migration and creation of fertile spawning habitat.
