Phytophthora cinnamomi disease

Healthy natural environments provide a range of direct and indirect benefits to the community, in addition to the intrinsic value of biodiversity. The disease caused by the introduced plant root pathogen, Phytophthora cinnamomi, threatens these values and benefits. This disease is often difficult to detect and its impact may be significant before it is detected. Depending upon environmental conditions and plant susceptibility, the pathogen can destroy vegetation communities. Phytophthora cinnamomi threatens several plant species with extinction.

Key threatening process

The disease caused by Phytophthora cinnamomi is listed as a key threatening processes under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999.

Threat abatement plan

A threat abatement plan has been prepared to provide a national strategy to manage the impact on biodiversity.


The department has commissioned research into natural and induced resistance in Australian native vegetation of Phytophthora cinnamomi and innovative methods to contain and/or eradicate within localised incursions in areas of high biodiversity in Australia via the following three reports.
