Management Notes (for the Swan NRM Region)
Kate Brown and Karen Bettink, Thursday 21 December 2017

Alternative Names. coastal tea tree.

General Biology. Growth form. Shrub. Reproduction. Seed. Dispersal. Wind, vehicles, soil movement, water, garden refuse. Time to first flowering. 4 years. Vegetative regeneration strategy. Occasionally resprouts from base. Seedbank persistence. Short, days-1 year. Fire response. Adult plants are killed by fire, seed is released from woody fruits and germinates prolifically in post fire conditions.

Notes. Seeds released en masse when plants are damaged or streesed, including herbicide application, mechanical damage or fire.

Additional information. Origin. south-eastern Australia. History of use/introduction. Garden escape, planting for dune stabilization and for windbreaks.

Suggested method of management and control. Hand pull seedlings. Fell mature plants. Resprouting has been recorded in some areas. Where resprouting has been observed, apply 250 ml Access® in 15 L of diesel to bottom 50 cm of trunk (basal bark). 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.
