Dieback-free basic raw materials (BRM)

VISIT BRM PROJECT PAGE

This project will facilitate the development of marketable dieback-free basic raw materials, using innovative and scientifically validated methods of eliminating the pathogen Phytophthora cinnamomi from commonly infested substances such as laterite gravel.

Phytophthora Dieback is a key threatening process for over 230 EPBC Act-listed species. One of the major vectors for spread of dieback is the movement of infested BRM, which include gravel, sand, clays, and limestone. A key BRM use which presents dieback risk to natural landscapes is roadbuilding, for which over 8 million cubic metres of laterite gravel is used across WA alone each year.

This project received grant funding from the Australian Government Saving Native Species Program, for innovative projects, including new technologies, methods and tools, to reduce threats to threatened species and ecological communities.  DWG Inc.’s project partners include the Department of Biodiversity Conservation and Attractions WA, Main Roads WA, Murdoch University, Binalup Aboriginal Corporation, Heidelberg Materials and contractors Culford Agri Industry and ArborCarbon.

Green Card training

Green Card Training (Phytophthora Dieback Hygiene) offered by the Dieback Working Group is recognised as the gold standard in environmental biosecurity hygiene training by WA government authorities. This training equips participants with the skills and knowledge you need to manage your risk of spreading Phytophthora Dieback on-ground.  Many industry employees are also now required to complete training before commencing work on DBCA managed lands.

DWG Green Card Trainees who successfully complete the course receive the skills and knowledge to be able to understand the nature of the plant disease Phytophthora Dieback, how it is managed and what steps they need to take to ensure the disease isn’t spread through their in-field activities. Trainees complete the course with the skills for completing a clean-down of a vehicle or piece of equipment relevant to their work practices.

Protecting Lesueur National Park’s Extraordinary Biodiversity

Lesueur National Park is one of Western Australia’s most botanically diverse and remarkable landscapes, supporting an extraordinary range of native plants and wildlife. Protecting this unique biodiversity from dieback is at the heart of this project.

Funded through the Western Australian Government’s State NRM Program, the project’s primary focus is the sealing of a 1 km stretch of Cockleshell Gully Road to help protect Lesueur National Park from a nearby Phytophthora cinnamomi infestation. The road previously provided a pathway for potentially dieback-infested soil to be transported towards the park through vehicle movements. Sealing the road is a significant on-ground intervention that will help reduce this risk and protect the park’s highly valued native vegetation.

Alongside this major infrastructure project, the Dieback Working Group is working with DBCA, NACC NRM, the Shire of Dandaragan, Aboriginal Elders, rangers and local communities to build awareness and strengthen practical dieback management across the region.

The project includes a range of community events, guided bushwalks and hands-on education activities, including sessions featuring Detection for Good’s dieback detector dog ‘Kelly’ – where community members can learn about the role these specially trained dogs play in detecting Phytophthora. Participants can also learn about dieback hygiene, plant health and practical actions they can take to help prevent the spread of the disease. Green Card training is being delivered to local organisations, rangers and volunteer groups to build practical skills in dieback management.

New signage is being installed at key locations to explain the threat of dieback, highlight the importance of the road upgrade and show visitors how they can help protect the park. A broader communications and education campaign is also helping share dieback information with communities across the region.

By combining a major on-ground investment with community engagement, education and practical training, this project is helping reduce the immediate risk of dieback reaching Lesueur National Park while empowering the community to play an active role in protecting its extraordinary biodiversity.

Discovering Dieback Schools Program

Discovering Dieback is an environmental conservation theme program for upper primary that teaches about Western Australian ecosystems and invasive species that threaten them with a focus on the plant disease Phytophthora Dieback.

The original program began in 2006 with a group of concerned teachers and students at Armadale Primary School and has developed over the years with funding from the Government of Western Australia through the State Natural Resource Program to become an award-winning education program. The program is currently under redevelopment to keep in alignment with the revised Science curriculum, to return to schools in 2025/26.

Teaching primary school students about Phytophthora Dieback is one of the most important ways we can educate the community about this devastating plant disease. 

The Discovering Dieback Year 6 program consists of:

  • Presentations at professional events for teachers including lesson plans (optional, includes CONASTA 2025)
  • 8 lessons (background material, powerpoints, activities and worksheets) aligned with revised Science curriculum for teaching from 2026 (free to download)

An optional extra available through DWG is a DWG officer-delivered in-school visit or external field trip for students. This showcases the plants referred to in the lessons, as well as demonstrating activities such as stem injection with phosphite to protect trees from Dieback.

Opportunities are available to fund Dieback Busting field days, a great family event for Dieback Education, in your local community.

Dieback Unearthed

Delivered as a partnership between the Dieback Working Group and Binalup Aboriginal Corporation, ‘Dieback Unearthed’ represents a step forward in delivering effective education and generating positive behaviour change for environmental biosecurity hygiene.  

At its heart, the project is a co-ordinated education and events campaign on Phytophthora Dieback which will target multiple key sectors. The project’s primary objective is to bolster awareness, knowledge, and capacity in stakeholders surrounding the biodiverse Fitzgerald River National Park; one of the last dieback-free wildernesses in southwest WA. Important information on generating positive behaviour change will be published for adoption by the wider Dieback management community.  

This project is supported by funding from the Western Australian Government’s State NRM Program and received grant funding from the Australian Government.
