State priority weed category – PREVENTION

The following weeds have not established self-sustaining populations in NSW and pose a significant biosecurity risk to the state. Prohibiting these weeds from the state to prevent the biosecurity risk posed is a reasonably practical objective.

Biosecurity Act requirements and strategic response in the region

Mandatory Measure (Division 8, Clause 34)

Duty to notify on importation of plants into the state:

  1. A person must not import into the State a species of vascular plant (Tracheophyta) if the species is not currently present in the State unless the person has, at least 20 working days before the plant is imported into the state, notified the species of plant and its proposed location within the State.
  2. The notification is to be given to the Secretary and is to be given in accordance with Part 6.
  3. A species of plant is taken not to be present in the state if the National Herbarium of New South Wales does not show it as being present in the state.

Note. See http://plantnet.rbgsyd.nsw.gov.au

 

Common name Scientific name
All species of vascular plant Tracheophyta Tracheophyta

 

Biosecurity Act requirements and strategic response in the region

 Prohibited Matter (Part 4, Biosecurity Act, 2015)

A person who deals with any biosecurity matter that is Prohibited Matter throughout the State is guilty of an offence.

A person has a biosecurity duty to ensure that so far as is reasonably practicable, the biosecurity risk posed by prohibited matter is prevented, eliminated or minimised.

A person who becomes aware of, or suspects, that a prohibited matter event has occurred, is occurring or is about to occur has a biosecurity duty to immediately notify the local control authority about the prohibited matter event.

Regional strategic response:

  • Implement quarantine and/or hygiene protocols.
  •  Undertake high risk sites and pathways analysis to identify potential introduction areas and preventative options.
  • Trigger rapid response protocol.

State priority weed category – ERADICATION

The following weeds are present in limited distribution and abundance and pose a medium to high biosecurity risk to NSW. The measures established under the control orders are necessary to prevent, eliminate, minimise or manage the biosecurity risk or biosecurity impact.

Biosecurity Act requirements and strategic response in the region

The boneseed control zone is the whole of NSW

The parkinsonia control zone is the whole of NSW

The tropical soda apple control zone is the whole of NSW

Control measure - owners and occupiers of land

  1. The owner or occupier of land in the control zone on which there is a new infestation of boneseed, parkinsonia or tropical soda apple must notify the local control authority for that land as soon as practicable of the following information:
    1. the person’s full name and contact details, including a telephone number
    2. the address of the land, including the lot and deposited plan number and the property identification code for the land (if these are known)
    3. any other information that is requested by the local control authority.
  1. The owner or occupier of the land must ensure that the land is kept free of boneseed, parkinsonia or tropical soda apple by immediately destroying all boneseed, parkinsonia or tropical soda apple on the land. This requirement applies to any new infestation as well as any subsequent generations of boneseed, parkinsonia or tropical soda apple on that land.
  2. The owner or occupier does not need to comply with subclause (1) if they know that notification of the new infestation on the land has already been given to the local control authority of that land.

Control measure – persons dealing with carriers

A person who deals with a carrier of boneseed, parkinsonia or tropical soda apple must take all reasonable steps to ensure that the carrier is not moved from the land with any boneseed, parkinsonia or tropical soda apple on it, attached to it, or contained in it, before the carrier is moved from the land.
