What is happening?

The Quarantine Area (QA) for the exotic pest Polyphagous shot-hole borer (PSHB) has been expanded, as of Tuesday 16 November 2021, to include the City of Canning. This has been designated by the Department of Primary Industries and Regional Development (DPIRD).

Requirements for the disposal of green waste

Movement of wood and green waste from within the City of Canning will be restricted for a minimum of six months, as these materials act as hosts and could potentially spread the borer. This could result in Fusarium dieback and tree death. The disposal requirements include:
  • untreated wood that is used for construction, fencing and furniture and green waste material including cut branches or prunings, bark, firewood, plant mulch and wood chips
  • wood more than 2.5cm in diameter must be chipped into pieces (less than 2.5cm in diameter) before leaving the QA.
  • living plants with woody stems greater than 2cm must not leave the QA. A living plant is any plant, organ or plant part (including plant cutting) with woody stems that are greater than 2cm in diameter
  • movement within the QA is permitted unrestricted
  • a permit is required if these conditions are unable to be met
  • any gardening machinery or equipment used for tree lopping, gardening, mulching, wood chipping or handling green waste must have all wood material removed before moving outside of the quarantine area
  • green waste can be disposed of as normal, within your general waste rubbish bin supplied by the City
  • if you're engaging a contractor for larger tree removals, the contractors have the obligations to comply with the quarantine requirements.
