Three examples of surveyed ephemeral gullies, each one with different type and density of vegetation. (A) Restored gully with dense vegetation cover of the gully floor with native species, (B) Restored gully with intermediate cover of the gully floor with native and exotic species, and (C) Active gully system. Active gully systems developed on highly weathered or loose parent material are an important source of runoff and sediment production in degraded areas. However, a decrease of land pressure may lead to a return of a partial vegetation cover, whereby gully beds are preferred recolonization spots.
