Management Notes (for the Swan NRM Region)

General Biology. Growth form. Shrub/Small Tree. Reproduction. Seed. Dispersal. Water, bird, ants, soil movement, garden refuse. Time to first flowering. 2 years. Toxicity. Cyanides in the leaves can lead to stock poisoning. Vegetative Regeneration Strategy. Occasionally resprouts. Does not produce root suckers. Seedbank persistence. Long, 10+ years. Fire response. Fire stimulates mass germination of soil stored seed.

Notes. Dense stands can significantly increase nitrogen content in soil.

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

Suggested method of management and control. Hand pull seedlings. Fell mature plants. Apply 250 ml Access® in 15 L of diesel to basal 50 cm of trunk, or cut and paint or drill and fill with 50% glyphosate. Older plants can be ringbarked. Monitor site for recruitment from seedbank. 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.
