Environmental Weeds

What are they?

There are many plants which could be classed as environmental weeds or pest plants.

Some ornamental plants, grown in home gardens, may be considered a threat. They may threaten human health, native bushland and natural resources such as waterways, creeks and rivers.

They are often hard to eradicate, spread rapidly and some have toxic or harmful properties.

They can become a serious weed problem if prunings, clippings and unwanted plants are discarded onto vacant land or dumped into natural bushland.

What can you do?

  • The responsibility for the control of these plants lies with everyone as a General Biosecurity Duty, under the Biosecurity Act 2015.
  • Common sense and good gardening practices help with their control.
  • All unwanted plant refuse should be mulched, composted or taken to designated council disposal areas.
  • This helps reduce the chance of garden escapes.

NOTE :  

All plants are regulated with a general biosecurity duty (GBD) to prevent, eliminate or minimise any biosecurity risk they may pose, including Environmental Weeds.  Simply, the general biosecurity duty (GBD) means that all public and private land owners or managers and all other people who deal with weed species (biosecurity weeds matter) must use the most appropriate approach to prevent, eliminate or minimise the negative impact (biosecurity risk) of those weeds.

The general biosecurity duty (GBD) supports the principle of shared responsibility, and means everyone is doing what is reasonable for them to do to prevent, eliminate or minimise biosecurity risks. A general biosecurity duty (GBD) that provides that people who deal with biosecurity matter or a carrier, and who have knowledge of the biosecurity risks posed are to take reasonable steps to manage those risks.
