Management Notes (for the Swan NRM Region)
Kate Brown and Karen Bettink, Thursday 8 September 2016

General Biology. Growth form. Tree. Reproduction. Seed, root suckers. Dispersal. Birds, water, ants, garden refuse, soil movement. Time to first flowering. 5 years. Vegetative regeneration strategy. Resprouts, produces root suckers. Woody structure. Diffuse porous. Seedbank persistence. Soil, long, 50+ years. Fire response. Fire stimulates mass germination of soil stored seed. Adult plants will resprout and produce root suckers following fire.

Notes. Regenerates after disturbance to form dense thickets. Is a potentially serious weed of wetlands from Augusta to Albany.

Additional information. Origin. Eastern & south-eastern Australia. History of use/introduction. Garden escape, restoration plantings, commercial plantations.

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.
