Extensive work has been carried out to determine the management strategies that best control 'Nassella trichotoma' (serrated tussock) throughout the south eastern regions of Australia and New Zealand. 'N. trichotoma' infested areas on the Northern Tablelands of New South Wales (NSW) in the early 1960s and it went unnoticed and uncontrolled for many decades. Since the recognition of 'N. trichotoma' on the Northern Tablelands as a weed of significance, measures have been taken for its control and management. Many of the ideas for control have been taken from the practices that are used on current infestations in the south eastern areas of Australia and in New Zealand. The variation in the environmental conditions and characteristics of infestations between these southern areas and the Northern Tablelands are the motive for development of more specific management options.
