What is a Priority Weed?

LantanaEach of us probably has a definition of the term ‘weed’ which does not exactly coincide with anyone else’s definition.  Broadly speaking a ‘weed’ is best defined as a plant growing out of place or where it is not wanted.

Weeds cost the Australian community some $4 billion annually.  Over two-thirds (66%) of our weeds were introduced legally as attractive garden ornamentals.  Every year at least 12 new species become naturalized somewhere in Australia.  Of these at least four become significant or major weeds.

Although there are many plants that could be classed as weeds, only those plants that spread widely and have a detrimental effect on the environment, or economy are considered as candidates for declaration as a priority weed.  Declared priority weeds are proclaimed by Order of the Minister for the Department of Primary Industries under the Biosecurity Act 2015.  There is a legal requirement on landowners and occupiers to control these weeds once declared.  A weed is declared priority only if reasonable and enforceable means are available to control it.

These may also be used to transition from an emergency situation when erdaication is still considered feasible. Control orders also provide the flexibility to respond to changing environmental or operational conditions.

Biosecurity Zone
