Dieback Treatment and Management

Phytophthora (Pc) dieback is a grave threat to WA’s native bushland.

Our Environmental team have all the experience and accreditations required to treat and protect your bushland or reserve from infection. This comprehensive process starts with detailed assessment and mapping and covers post-treatment rehabilitation and training.

Collating data and samples

Our assessment includes reviewing all database records, including soil types and groundwater data.

After this, we conduct detailed field assessments and collect samples of infected areas according to DBCA recommendations. These are analysed at the Murdoch University Centre for Phytophthora Science and Management (CPSM).

Determining cause of death

We determine the correct cause of death by assessing the plant types found in the area and looking out for any recently dead specimens of a susceptible species, also known as Indicator Species Death (ISDs).

It is critical to complete this process thoroughly. This cancels out other influences like drought, other infections, external vectors like rabbits or native animals, or negligent hygiene practices.

Mapping infection

Using the data we design and implement systematic surveys of the affected and adjacent bush areas.

From here, we map out the bushland area into low and high impact infected areas and zones. We use this to create the optimal treatment plan for your requirements.

Coverage and treatment

We can administer a variety of treatments according to the plant requirements and severity and spread of infection. Our team are fully trained to inject and spray susceptible vegetation, including all understory and adjacent vegetation.

You will receive regular progress reports and full documentation of our treatments at every step of this process. This includes relevant GPS data for GIS.

We use DWG recommended phosphite solution and are licensed by the WA Department of Health. Our treatments follow the DBCA’s Interpreter’s Manual, and we hold the required APVMA permit for off-label phosphite use.

Phosphite solution increases the plant’s natural defences against infection, and prevents spread of infection to other uninfected plants in the area.

Rehabilitation

Once treatment is complete, we re-evaluate the area. We determine the best practice for ongoing protection, management, and prevention of Pc dieback infection.

It’s important to rehabilitate any damaged areas and protect plants after treatment. We can strengthen your bushland with:

  • An ongoing phosphite treatment plan
  • Replanting of damaged plants
  • Introduction of dieback resistant species
  • Setting up correct green paths, signage, and fencing

Prevention is key

Having an effective prevention strategy is the only way to ensure that your bushland is safe from Phytophthora dieback. A key factor of success is maintaining strict quarantine and hygiene practices across your team.

Our staff have the experience and qualifications to assess and treat your bushland before the infection spreads.  We can also train your team to do the same and prevent any reoccurring infection.

Qualifications

Our staff members are fully qualified with the following certifications:

  • AHCCHM303A – Prepare and Apply Chemicals
  • AHCCHM304A – Transport, Handle and Store Chemicals
  • AHCPMG302A – Control Plant Pests, Diseases and Disorders

Training your team
