About Noxious Weeds


Legislation has recently changed in regards to noxious weeds, the Biosecurity Act 2015 was passed by Parliament in September 2015 and will replace all or part of 14 Acts including the Noxious Weed Act,1993. This webpage has not been updated yet to reflect the new legislation.

Not all weeds identified as noxious in Lane Cove at present grow here but they have the potential to become serious weeds or already are serious weeds elsewhere in NSW. They are identified so that they can be eradicated or controlled as soon as they appear.

What is a Weed?

Weeds are plant species that are out of place in the natural environment. They can often produce vast quantities of seed which spread across into the natural ecosystem by wind, water, birds (and other animals) and humans.

What are Noxious Weeds?

Noxious weeds are those plant species declared by NSW Agriculture and Council under the Noxious Weeds Act, 1993. They are declared because they threaten human health and property, agricultural productivity and natural biological diversity.
A comprehensive listing of all noxious weeds within Lane Cove Councils' control area is available here.

What are Environmental Weeds?

Environmental weeds are introduced plants which have invaded natural ecosystems. These weeds become highly invasive due to their rapid growth, high fecundity (seed production and longevity) and very effective dispersal methods. Some environmental weeds are also classified as noxious weeds.

Noxious and environmental weeds compete with native plants for sunlight, moisture and nutrients. They can dominate and stifle the germination of native plants.

What is the Noxious Weeds Act, 1993?

The Noxious Weeds Act, 1993 is the legislative Act governing all aspects of noxious weeds throughout NSW. Under this Act, Lane Cove Council can enforce penalties on land holders failing to control noxious weeds growing on their property. The Act also classifies noxious weeds into five control categories. The NSW Department of Primary Industries is the government authority that has responsibility for and declares noxious weeds.

Who is responsible for controlling Noxious Weeds?

Owners and occupiers of property in the Lane Cove Municipality are obliged to comply with the Noxious Weeds Act, 1993.

Lane Cove Council also has the responsibility to comply with the Noxious Weeds Act on land under its control. Government land is the responsibility of the government department, which has control over the land.

For each category of noxious weed, there is specific criteria for control of those weeds. Noxious weeds in the category Class 4 have specific management plans which can be viewed below.
