Management Notes (for the Swan NRM Region)
Kate Brown and Karen Bettink,
Monday 23 May 2011
General Biology. Growth form. Shrub/Small tree. Reproduction. Seed. Dispersal. Water, bird, ants, soil movement, garden refuse. Vegetative regeneration strategy. Resprouts, produces root suckers. Seedbank persistence. Long, 5+ years. Fire response. Fire stimulates mass germination of soil stored seed. Adult plants can resprout from base and from root suckers following fire.
Notes. Root suckers form with minimal root disturbance.
Additional information. Origin. Western Australia. History of use/introduction. Garden escape, restoration plantings.
Suggested method of management and control. Hand pull seedling. For mature plants apply 250 ml Access® in 15 L of diesel to basal 50 cm of trunk (basal bark), 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.
