- Reshaping of severe gully erosion to stabilise batters and allow water to flow more smoothly minimising ongoing erosion risks – approx. 1.5ha;
- Regrading and shaping multiple areas with sheet erosion – approx. 8.5ha;
- Supply and spread of approx. 100T of gypsum over eroded areas to improve soil structure;
- Hydromulching 1.5ha of reshaped gully to assist stabilisation while promoting native vegetation establishment;
- Direct seeding approx. 8.5ha of areas with a tailored mix of native species; and
- Cultivation of all areas to increase water infiltration, reduce runoff and provide a suitable medium for seeding and hydromulching
