Sodic subsoil. Moderate grazing pressure. Significant surface water flow during the Wet season. Disturbance of natural springs and drainage lines should be avoided. Where disturbance is unavoidable erosion and sediment control planning will be required. This unit closely aligns with land unit 4g6 in the VRD however it is better described as drainage rather than a sandstone hills unit. Springs are defined as wetlands. Wetlands are significant habitats that are critical to a large number of wildlife species and many contain animal and plant species that are found nowhere else. These habitats are vulnerable to degradation by fire, over grazing, feral animals and weed invasion.
