Intention to Declare a Number of Plants Under the Weed Management Act 1999

The Department of Primary Industries, Parks, Water and Environment is seeking public comment on its intention to declare 32 plants as weeds under the Weed Management Act 1999 (Table 1).  The plants proposed for declaration 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, are proposed for declaration to assist nation-wide management efforts and prevent the sale and trade of species that may become serious weeds in other jurisdictions.

Statements of Intent have been developed that provide an overview of the species and the reasons for declaration.  The Statements of Intent are available at:


Statement of Intent to Declare Erica species
Statement of Intent to Declare Weeds of National Significance
Statement of Intent to Declare Ilex aquifolium

Declaration Proposal for Erica species

Declaration Proposal for Ilex aquifolium

Risk assessments have been completed for each of the Erica species and Ilex aquifolium, and 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 for the WoNS species as they are the subject of national arrangements and have been assessed as part of their original nomination.

Declaration will provide inspectors with the power to require weed control if deemed necessary and to prohibit sale and import into Tasmania. It will also trigger 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.
