Abstract
The concentrations of nutrient elements in water were monitored in the unburned watershed of Dogfish Lake and in the burned watersheds of Lamb and Meander Lakes for 3 yr following the 1971 Little Sioux Wildfire in the Superior National Forest, northeastern Minnesota [USA]. Lamb Lake watershed contains fine-textured soils of glacial lacustrine origin; the other 2 watersheds contain coarse-textured soils derived from glacial till or granite bedrock. Nutrient concentrations of various hydrologic components were determined largely by soil type rather than by the effect of fire. Nutrient concentrations of lake waters and input streams were unaffected by the fire, due to immobilization of nutrients in the soil and to uptake by prolific post-fire revegetation.This publication has 3 references indexed in Scilit:
