Some effects of clearcutting on salmon habitat of two southeast Alaska streams /

Surface runoff is sharply reduced by revegetating damaged watersheds. Legum- es planted on severely gullied land in South Carolina greatly reduced peak flows and stopped soil loss (Metz 1958). Two years after revegetation, stormflow on a mountain farm in North Carolina had returned nearly to preclearing levels (Dils 1957). Reforestation of the White Hollow watershed, Tennessee, reduced peak discharges 73-95 percent of levels observed before the area was reforested (Tennessee Valley Authority 1961). In Ohio, stormflow reductions following reforestation ranged from 52 percent in small storms to 84 percent in large storms (Hill I960).
