weeds and seeds declaration

Highly invasive weeds threaten grazing lands, waterways, national parks and urban environments. In Australia, the cost of weeds on agriculture has been estimated at $4 billion a year (excluding the impacts on the environment and community).

Preventing the spread of weeds is difficult, as many weeds have physical characteristics that allow their seeds and other reproductive parts to be easily transported over long distances.

Whenever people or animals move through weed-infested areas, there is a chance that weeds will be spread to new areas. Weeds have the potential to adversely alter ecosystem function, reduce primary industry productivity and profitability, and seriously limit the long-term sustainability of all the state’s agricultural and natural resources.

Under the Biosecurity Act 2014 everyone has a general biosecurity obligation (GBO) to prevent or minimise the risks of spreading weeds. To meet your GBO consider the following information:

One of the most cost-effective ways to control weeds is to stop them spreading and eradicate new infestations.

More than 90 species of weeds have been recognised as prohibited or restricted invasive plants in Queensland under the Biosecurity Act 2014. Unless we take action now, the number of new weeds will continue to climb, adversely affecting our economy, environment and health, and our enjoyment of the outdoors.

Weed seeds ‘fly’ on the wind, ride river currents, hitch a lift on shoes, clothing, vehicles and machinery, and attach themselves to pet fur, livestock and wildlife. Seeds and plant parts can also hide in soil, water, mulch, animal feed and herbivore faeces.

The Biosecurity Act 2014 requires everyone to take all reasonable and practical steps to minimise the risks associated with invasive plants and animals under their control. This is called a general biosecurity obligation (GBO).

Weeds can cause serious economic, environmental and social problems. Queensland farmers play an important role in preventing weeds from spreading.

You can use the following strategies to prevent weeds from spreading on and from your property.
