What can you do?
Although there is significant uncertainty surrounding the causes of dieback, preventative actions can avoid tree stress and tree susceptibility to dieback:
- Encourage diversity of native plants in the understorey to encourage birds to nest and other animals to forage. This action can inhibit excessive insect attack and restrict stock grazing or machinery that compact the soil. Encourage deep-rooted vegetation to help regulate the water table.
- Help natural regeneration of new eucalypts by rotational grazing and exclusion of soil disturbance. Fences can assist in this and allow the soil to recover from compaction. Refrain from removing dead tree hollows and dead shrubs, which can provide habitat for native animals.
- Limit excess nutrient influx from fertiliser and herbicide application. Consider how off-target areas might be affected by fertiliser/herbicide regimes.
- Control of insects can be effective on a tree-by-tree basis to reduce stress, but should only occur when the tree becomes significantly threatened. Single trees can be treated with insecticide and soapy water and the removal of affected limb
