Weeds awareness & information

The Moreton Bay Region contains a diverse range of natural habitats such as rainforests, woodlands, vine forests, coastal heathlands, freshwater wetlands, mangrove forests and dunes. These habitats are being threatened by invasive weeds.

Why are weeds a problem? 

Weeds in natural areas displace native vegetation that provides habitat for wildlife, restrict water flow, and deplete oxygen in water bodies.

Most invasive weeds are not native to Australia; however, some native plants have become invasive weeds as their prolific growth in disturbed areas outcompetes most other native plants. Examples are the fishbone fern and the umbrella tree.

What can we do?

You can join the battle against weeds by learning to identify weed species and managing weeds on your property. Moreton Bay Regional Council offers Voluntary Conservation Programs (including Bushcare, Land for Wildlife and Backyards for Wildlife) that provide the community with opportunities to learn about our environment and conservation.

What Council does

Moreton Bay Regional Council manages weeds on Council reserves and properties and waterways across the region.

Weed Legislation

It is everybody’s responsibility to control weeds on their land.

On the 1 July 2016, Biosecurity Queensland replaced the Land Protection (Pest and Stock Route Management) Act 2002 for the legislative management of pest species in Queensland.

All residents now have a general biosecurity obligation, which means that you need to ensure that your activities do not spread a pest, disease or contaminant and ensure:  

  • Take all reasonable and practical steps to prevent or minimise each biosecurity risk
  • Minimise the likelihood of the risk causing a biosecurity event and limit the consequences of such an event; and
  • Prevent or minimise the adverse effects the risk could have and refrain from doing anything that might exacerbate the adverse effects.  

 Declared weed species are listed by Biosecurity Queensland as restrictive invasive plants for management: 

  • High Risk weeds must be controlled by landowners on their property and must not be introduced, kept, released or sold without a permit - penalties apply. High Risk weeds are not commonly present in the region but have the potential to seriously threaten primary industries, the natural environment, livestock, human health and people's livelihoods. Landowners are required by law to keep their land free of High Risk weeds and report any suspected sightings toBiosecurity Queensland. For a full list of prohibited species in Queensland please visit the Biosecurity website
  • Medium Risk weeds must be controlled by landowners on their property and must not be introduced, kept, released or sold without a permit - penalties apply.
  • Low Risk weeds must be controlled by landowners whose property is adjacent to an environmentally significant area and must not introduce, supply, release or sell these weeds without a permit - penalties apply.
  • Non Restricted Invasive Weeds are plants which can disrupt native flora communities and ecosystems. There are no legislative requirement or restrictions on invasive weeds; however, landowners are encouraged to control non-declared weeds on their property to reduce their impacts.

More information on weed control legislation and the declared classes of weed species can be found on the Queensland Government Department of Agriculture and Fisheries website
