Management Notes (for the Swan NRM Region)
General Biology. Growth form. Tree. Reproduction. Seed, suckers. Dispersal. Birds, mammals. Time to first flowering. Normally 10-12 years, under irrigation 4-5 years. Vegetative regeneration strategy. Resprouts from base and can produces root suckers. Woody structure. Diffuse porous. Seedbank persistence. Long, 5+ years. Fire response. Fire kills young plants but older plants will resprout following fire.
Notes. A serious bushland weed in South Australia. Forms mixed age thickets that virtually preclude native plant recruitment. Eastern Australian populations have been introduced from South Africa (ssp. cupidata) and South Australian and Western Australian populations have originated in Europe (ssp. europea).
Additional information. Origin. Mediterranean. History of use/introduction. Garden escape, commercial plantations.
Suggested method of management and control. Hand pull or dig out seedlings and small plants ensuring removal of all roots. For mature plants cut to base and paint 50% glyphosate or apply 250 ml Access® in 15 L of diesel to base 50 cm of trunk (basal bark). Monitor sites for seedling recruitment. 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.
