A ground cover for controlling soil erosion and retarding vegetation growth on sloped ground includes a plurality of spaced apart water control baffles and a series of thin, sheet-like membranes between pairs of the water control baffles. The ground cover is secured to the ground by a plurality of ground engaging fasteners. The water control baffles preferably include a vertical leg having a plurality of apertures therethrough, and a ground engaging leg, which is substantially horizontal to the ground, for receiving the ground engaging fasteners. The membranes allow water to flow through the membrane while preventing erosion of the soil underneath the membrane.
