Willow
Released/reviewed: 2003
Most species of willow are Weeds of National Significance. They are among the worst weeds in Australia because of their invasiveness, potential for spread, and economic and environmental impacts. They have invaded riverbanks and wetlands in temperate Australia, occupying thousands of kilometres of streams and numerous wetland areas.
Key points
- Early detection and control are essential to prevent the spread of new infestations.
- Most willows are easily spread by stems and twigs breaking off and taking root.
- Some varieties of willow can also spread by seed, which can be carried up to 100 km by wind or water.
- Control techniques need to be carefully chosen to minimise unintended impacts. Stem injectioof registered herbicide is recommended.
- Follow-up monitoring and control of regrowth(from stumps, pieces of stems or seeds) may be required for 3-5 years after initial control.
