Catchment deforestation increases the transport of eroded materials to aquatic systems. Records for denuded watersheds often show increases in sediment yield in excess of one order of magnitude over yields from relatively undisturbed catchments (Davis 1976; Oldfield 1977; Foster et al. 1985; Dearing 1991a, b). This increased deposition of sediments can be harmful to aquatic biota (Cordone and Kelly 1961; Lloyd et al. 1987; Newcombe and MacDonald 1991; Waters 1995). In particular, elevated erosion as a result of riparian clearcutting is recognized to pose a serious threat to the maintenance of commercially important fish stocks (Murphy et al. 1981; Moring 1982; Bisson and ...
