Management - pH

Management practices to reduce the load of acid entering a wetland:

• Acid Sulphate Soil (ASS) Management Plan
• Acid Sulphate Soil risk mapping
• Adequate buffer zones
• Appropriate liming rates
• Best practice ASS management
• Drain shallowing
• Government regulation
• In-drain structures to prevent low-lying areas from overtopping with tidal water
• Re-establishment of native wetland species
• Rehabilitation of ASS scalds and the reintroduction of natural wetting and drying cycles, utilising seasonally ponded freshwater
• Stock management (off-stream watering, fencing out of waterways)
• Tidal flood gate management to buffer low pH water
