Abstract

After the Valley Complex Fire burned 86 000 ha in western Montana in 2000, two studies were conducted to determine the effectiveness of contour-felled log, straw wattle, and hand-dug contour trench erosion barriers in mitigating postfire runoff and erosion. Sixteen plots were located across a steep, severely burned slope, with a single barrier installed in 12 plots (four per treatment) and four plots left untreated as controls. In a rainfall-plus-inflow simulation, 26 mm h-1 rainfall was applied to each plot for 1 h and 48 L min-1 of overland flow was added for the last 15 min.
