Key findings • Gullies are vulnerable to ongoing erosion because they concentrate runoff and have steep walls. Today’s gullies are a legacy of past grazing impacts. • The dominant source of sediment from gullies in grazed rangelands is erosion of gully walls, while head cut erosion also contributes. • Sediment losses are lower from gullies with more vegetation cover. • Gully erosion rates are correlated with annual rainfall.
