Wollondilly Shire Council is committed to the control and eradication of weeds, wherever they may grow.
Weeds are an ever-present threat to our local environment and way of life. Not only do they have a severe impact on agricultural activities, costing upwards of $7 billion nationally, but they also cause a number of other issues, including:
- Competition with commercial plants resulting in reduced productivity;
- Adverse effects on public infrastructure through the deterioration of roadways and waterways;
- Adverse effects upon human health from poisonous or irritating plants;
- Increased risk due to fire hazards created by uncontrolled weed growth;
- Adverse effects on tourism and recreation;
- Deterioration of natural ecosystems, through competition with indigenous flora;
- Adverse effects upon the viability of rare or endangered species and ecological communities and other indigenous flora and fauna;
Weeds are generally divided up into two categories, noxious and environmental. To assist with the management of these weeds Council has developed the Wollondilly Weed Management Strategy.
Noxious weeds are those specifically identified by the NSW Department of Primary Industries, though may differ between local government areas due to differences in natural environments. Wollondilly Shire currently has 92 noxious species declared. To view a list of the declared noxious species in the Wollondilly Shire go to the NSW WeedWise website.
Noxious weeds are categorised into 5 classes:
Class 1 - State Prohibited Weeds
Plants that pose a potentially serious threat to primary production or the environment and are not present in the State or are present only to a limited extent.
Class 2 - Regionally Prohibited Weeds
Plants that pose a potentially serious threat to primary production or the environment of a Region.
Class 3 - Regionally Controlled Weeds
Plants that pose a serious threat to primary production or the environment of an area to which the order applies. Are not widely distributed in the area and are likely to spread in the area or to another area.
Class 4 - Locally Controlled Weeds
Plants that pose a threat to primary production, the environment or human health. Are widely distributed in an area to which the order applies and are likely to spread in the area or to another area.
Class 5 - Restricted Plants
Plants that are likely, by their sale or the sale of their seeds or movement within the State or an area of the State, to spread in the State or outside the State.
The Department of Primary Industries has written a handbook to help people use the correct chemicals on noxious weeds. To read, go to the Noxious Environmental Weed Control Handbook.
Environmental Weeds are those that, whilst not actually identified, still present a serious threat to the environment. Environmental Weeds in Wollondilly include Privet, Moth Vine, Madeira Vine, Giant Reed, and Balloon Vine.
