Abstract
Small streams differing in sediment composition were compared in logged and forested reaches to determine effects of accumulated fine sediment on stream communities under different trophic conditions. Three stages of forest community succession were studied in the Cascade Mountains: recently clear-cut area without forest canopy (5-10 years after logging); second-growth forest (30-40 years after logging); and old-growth coniferous forest (450 years old).
