Phytophthora cinnamomi is a species of water mould which can cause the plant disease commonly referred to as ‘dieback’ in susceptible native plants and forestry species. This pathogen has been recognised under the Environment Protection and Biodiversity Conservation Act 1999 as a serious threat to many native plant species and ecosystems.
Phytophthora dieback affects more than a million hectares of native vegetation in Australia and continues to spread. It can significantly change the structure and composition of native plant communities, leading to loss or degradation of habitat for dependent plants and animals.
The draft Threat abatement plan for disease in natural ecosystems caused by Phytophthora cinnamomi (2017) provides a national strategy to abate the threat and guide investment and effort by the Australian Government, state and territory governments, research organisations and non-government organisations.
