List of pests and diseases of trees and timber

Use our list below to become aware of the symptoms of Australia's most common pests and diseases, as well as those of exotic pests and diseases known to cause damage to forests overseas.

Insect pests and fungal diseases can damage shoots, leaves, crowns and stems, which can reduce tree growth and condition. If severe, the damage can cause trees to die. Insects and fungi can also reduce wood quality, resulting in lower yields and reduced timber prices.

Being able to recognise the symptoms of pests and diseases is critical for managing a healthy and productive forest. Read our general descriptions of the pests and diseases first, if you are unsure of the name.
