Soils have moderate levels of fine sand and silt. Extremely sodic subsoils with shallow buried horizons. Saline profile in some areas. Moderate grazing pressure. Any disturbance of wetlands and drainage systems should always be avoided. Where disturbance is unavoidable erosion and sediment control planning will be required. Channels and prior streams are largely forbland communities with the swales and backplains being generally woodlands. Channels and prior streams such as these are defined as wetlands. Wetlands 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.
