Possible control methods for weed removal are outlined Table 1, below. Experienced personnel with
training in weed management and identification should carry out weed removal. It is to be carried out by
means that do not pose a threat to adjacent native species. The rate of removal should be dictated by
bush regeneration principles working from good areas of bush to bad, making minimal disturbance and
allowing native plant regeneration to dictate the rate of weed removal. The temptation to remove all
weeds at once is to be avoided. Herbicide treatment of weeds is most effective when the weeds are
actively growing.

Weed pressure is likely to remain high through the maintenance period, particularly in freshwater /
terrestrial influenced areas.
