Myrtle Rust

Myrtle Rust National Symposium

Galvanising action to conserve native plant species threatened by myrtle rust

23-25 March 2021

The Foundation and partners recently convened the National Myrtle Rust Symposium, with over 200 delegates either attending in-person or online.

The symposium brought together key stakeholders together to build a community of interest, share knowledge and build co-ordination and implementation of the National Action Plan. Presenters shared the latest research, response, surveillance and conservation activity, framed against the Action Plan. See our media release for more detail.

The Myrtle Rust National Action Plan

Myrtle Rust is a plant disease caused by the introduced fungal pathogen Austropuccinia psidii and it poses a serious and urgent threat to Australia’s native biodiversity. Myrtle Rust affects plant species in the family Myrtaceae (paperbarks, tea-trees, eucalypts, and lillipillies), which are key and often dominant species in most Australian ecosystems. To date it has proved capable of infecting 382 native species and this number is growing. Serious declines towards extinction are underway in some species, and broader ecological consequences are expected. Myrtle Rust is likely to have a significant impact on matters of national environmental significance protected under national environment law, including listed threatened species and ecological communities, wetlands of international importance, world heritage sites, and national heritage places.

The Myrtle Rust in Australia: National Action Plan can be downloaded (screen version) or booklet printable version here.

The Action Plan is supported by Myrtle Rust reviewed: The impacts of the invasive plant pathogen Austropuccinia psidii on the Australian environment (R.O. Makinson 2018), a valuable resource to be read in conjunction with the National Action Plan.

For further information on the Plan, please email info@apbsf.org.au.
