Management Notes (for the Swan NRM Region)

General Biology. Growth form. Shrub/Small tree. Reproduction. Seed. Dispersal. Water, birds, ants, wind, garden refuse, soil movement. Time to first flowering. 3 years. Vegetative regeneration strategy. Resprouts. Seedbank persistence. Long, 5+ years. Fire response. Fire stimulates mass germination of soil stored seed. Adult plants can resprout following fire.

Additional information. Origin. Eastern Australia. History of use/introduction. Garden escape. Similar native species. Acacia saligna.

Suggested method of management and control. Hand pull seedlings. Drill and fill with 50% glyphosate. Older plants can be ringbarked. Read the manufacturers' labels and material safety data sheets before using herbicides. For further information consult the Australian Pesticides and Veterinary Medicines Authority to determine the status of permits for your situation or state.
