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

General Biology. Growth form. Shrub. Reproduction. Seed. Dispersal. Explosive action, birds, ants, water, vehicles, slashing, soil movement, garden refuse. Time to first flowering. 2 years. Toxicity. Seeds are poisonous to humans and livestock. Vegetative regeneration strategy. Resprouts from base. Seedbank persistence. Long, 10+ years. Fire response. Adult plants may respout following fire. Fire stimulates germination of soil-stored seed.

Notes. Fixes nitrogen and increases soil fertility . Can increase frequency and intensity of fire.

Additional information. Origin. Northen Africa, southern Europe, western Asia. History of use/introduction. Garden escape.

Suggested method of management and control. Hand pull or dig out small seedlings ensuring removal of all roots. For mature plants cut and paint with 50% glyphosate or try basal bark with 250 ml Access® in 15 L of diesel. 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.
