Indicator description

What does the data tell us for 2005

Council is making an ongoing commitment to controlling pest plant species. Council is responsible for noxious weed control on, all roadside areas, Council owned land, land under the control of Council and Crown Land. Under the Noxious Weeds Act 1993, Council is also required ensure that private landowners and occupiers within the City area are taking reasonable and effective measures to control noxious weeds on privately owned land.

Council undertakes a substantial amount of spraying to eradicate noxious weeds each year. It is also has bio control programs in place for some weeds. The following table shows a list of Noxious Weeds with control programs in place, and the worst affected areas for each weed.
