Additional Plants Declared Weeds under the Weed Management Act 1999

The Department of Primary Industries, Parks, Water and Environment’s intention to declare an additional 32 plants as weeds under the Weed Management Act 1999 (Table 1), was given legal effect on 17 May 2017, when the Weed Management (Declared Weeds) Order 2017 (S.R. 2017, No. 25), was published in the Tasmanian Government Gazette. The declared plants are either:

  • Assessed as causing or having potential to cause significant environmental, economic and/or social harm to agricultural and/or natural systems in Tasmania, or;
  • Weeds of National Significance (WoNS) that whilst not necessarily posing a significant threat to Tasmania, have been declared to assist nation-wide management efforts and prevent the sale and trade of species that may become serious weeds in other jurisdictions.

The Declaration Proposal, Risk Assessment and Background Assessment for the Ericas and for Ilex aquifolium (Holly), show that each of these species has the potential to become a serious weed threat in Tasmania. These risk assessments, including both quantitatively based assessments and written assessments, are available via the links below. (Risk assessments were not done as part of this declaration for the WoNS species as they are the subject of national arrangements and have been assessed as part of their original nomination.)

Declaration now provides inspectors with the power to require weed control if deemed necessary and to prohibit sale and import into Tasmania. It has also triggered the statutory requirement to prepare a management plan for each declared weed. The plans describe the legal prohibition of the introduction, sale and distribution of declared weeds. They also outline regulatory measures for their early detection, control and eradication.
