1. Remove moribund grass to stimulate spring wild flowers and indigenous grasses
2. Remove non-ecological dead wood for ease of alien vegetation management
3. Second phase of management plan for invasive kikuyu grass
4. Manage bush encroachment by Gomphocarpus fruticosis.
5. Phragmites patches: To remove accumulated dead material. Regrowth will allow better access by waterfowl, and reduce height of regrowth which does not have to outcompete the previous season's.

Clear along fence with rake down to mineral soil.
Clear breaks along start and end of units. Wetline on the day if necessary.
Cut and rake around trees to drip line. Remove low branches.
Cut reeds near shore and pull away to create a damp mud line.
Cut long grass on banks and near fence where high flames might occur.
Avoid burning under trees with concentrations of leaf litter, especially oak trees.
Request Bad Boyz to direct traffic where necessary.
Proposed Lighting sequence – dependent on actual conditions
One fire head only to provide escape route for small mammals. Sequence of units depends on actual weather conditions.
Back burn when necessary, in consultation with Fire Department.
Risks and Mitigations
1. Dead trunks might smoulder for days - No inherent risk, but inform community in advance
2. Hot fire - Brief crew in advance
3. Dead stumps and high organic matter soil from which fire can travel underground - Monitor for several days post fire for smouldering and hot soil nearby. (Post-fire management)
4. Reeds close to burn area - Prepare area well. Cut reeds back and pull away by rake to create damp or wet area on shore. Light fire on the shore to prevent whirlwind developing and lifting embers.
