Forest, shrub, gardens, plantations.
Seeds dispersed by birds and mammals. Vegetative spread from suckering.
Impact on environment
Can form monocultures and invade intact native forest vegetation. Reduces native recruitment and restructures the vegetation profile of forests. May exacerbate impacts from animal pests such as possums and feral pigs by providing an important food source.
Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
Method: Dig out.
Plant parts requiring disposal: Seeds.
Disposal options: Remove to greenwaste or landfill if practical.
Biocontrol is currently not available for this species.
