WA at threat from dieback infection

WA at threat from dieback infection

Phytophthora dieback poses a critical danger to Western Australia’s biodiversity.

It threatens over 40% of our native plant species, in particular the south-west, and has already infected 80% of plant life in the Stirling Range National Park. This infection is difficult to identify and spreads easily through the movement of soil attached to footwear and vehicles.

Without immediate action, our rare bushland species could be wiped out.

Take early action

While there’s no cure for Phytophthora dieback yet, there are treatments and preventative measures available to stop the spread.

Our Environmental team provide native vegetation surveys and assessments for Pc dieback according to recommendations and standards from the Department of Biodiversity, Conservation and Attractions (DBCA). Samples are then analysed by the Centre for Phytophthora Science and Management (CPSM) at Murdoch University.

We use Dieback Working Group (DWG) recommended phosphite treatments to treat infected and adjacent areas.

Phosphite solution can increase the plant’s natural defences against infection, and boost the chances of uninfected plants to survive in infected areas. Our Environmental team is fully qualified and equipped with an off-label permit to use the phosphite solution from the Australian Pesticides and Veterinary Medicines Authority (APVMA).

Previous projects

We’ve built up a portfolio of infected nature reserves that we’ve managed and treated for the City of Cockburn. For each of the affected reserves, we carried out:

  • Mapping and confirmation of dieback infested areas
  • Collection of plant and soil samples for analysis of presence of Pc and other fungi
  • Treatment of the understory vegetation and susceptible tree species in infested and adjacent areas with phosphite solution
  • Providing detailed assessment reports and maps and all field data for the clients GIS system
  • Recommendations for rehabilitation of degraded infested areas
  • Training of client’s personnel for future prevention and management

Get ahead today

It is critical that we protect our wildlife from Pc dieback through early prevention. This is the only way to guarantee the survival of WA’s most unique plant species.

Luckily, our team can provide training for the correct management of future infection. This involves knowledge about the nature of the infection and strict hygiene measures to stop contamination.
