Information for Landowners in Fire Affected Areas

​​​This page provides specific information for landowners and land managers of areas affected by fire.

Prevention is better (and cheaper) than a cure. Left unmanaged, areas burnt by fires can face significant weed issues. But if carefully managed, fire events can present a weed management opportunity. Work with your Invasive Species Program Co-ordinator  to update your property management plan, and make a plan to make the most of this disruption to the weeds life cycles.

Transporting material

  • Care should be taken to avoid the spread of weeds onto road reserves and adjacent land.
  • Vehicles should be clean of soil, dried mud and weed material prior to entering the bushfire area and cleaned down after deliveries.
  • Vehicle cleaning should occur in a designated area to prevent weed dispersal and contain new infestations for easier management.
  • Keep an eye on local roadsides for 12 months afterwards, to detect new weed infestations.

Stockfeed on farm

  • Check the origin of your hay or grain stockfeed:
    - Has it come from a known weed infested area
    - Ask the supplier for written certification on any potential weed content.
  • Where possible source locally grown feed to reduce the chance of introducing new weeds that are not already present and known in your locality.
  • Keep records of purchased hay or grain stockfeed:
    - content
    - location sourced
    - producer
    - date purchased
    - transporter and
    - feed-out area.
  • Store and Feed-out in a confined area away from drainage lines (stock containment areas) to reduce the likelihood of weeds being spread throughout your property.
  • Monitor storage and feed-out areas regularly and be suspicious of unfamiliar plants that germinate for the next 12 months.
  • Utilise weed identification skills of Invasive Species Branch staff to identify suspect plants. Ask for help to properly identify suspect plants.


Building up stock numbers when recovering from an emergency is also another high risk activity that can introduce weeds.
  • Quarantine new stock for up to 14 days, allowing time for viable seed to pass through the animal.
  • Check for weed seed in fleece/ tails and continue to check for the weeds in areas with new stock.
  • Where possible, purchase shorn sheep.
  • When moving stock along roadsides try to avoid travel through known weed infestations.
  • Monitor stock routes for 12 months afterwards, to detect new weed infestations.

Planting Crops and Pasture

  • Verify your weed mapping and step up surveillance for new weed outbreaks. If you are unsure of what weed species were present prior to the fire check adjacent non-burned areas. Perennial weeds with well-established, deep root systems survive fire very well. Weeds such as flatweed, docks, sorrel and onion grass are the first plants to recover and are often prominent after fires.
  • Buy certified weed-free fodder and seed where possible. Keep records of where any seed is purchased.
  • Identify suspect plants as soon as possible.
  • Ensure all vehicles and equipment of agencies, contractors and advisers are clean and weed free before entering and leaving your property.
  • Increase integrated weed control treatments - the first two years are critical.

Informing workers, suppliers and volunteers

  • Install a sign at your front gate, so visitors are aware of potential weed hygiene issues
  • Include mention of weed risk and hygiene in briefing sessions/on-site meetings.
  • Establish strategic vehicle and machinery wash-down areas for vehicles and other machinery that need to work in high-risk weed spread areas.
