Species Notes for this Location:
Phytophthora cinnamomi is thought to have been brought to Australia by early European settlers. P. cinnamomi has been identified in all Australian states and territories. It has had devastating effects on native flora and fauna in Victoria, South Australia, Western Australia, Queensland and Tasmania (Pryce et al. 2002)
Management Notes for this Location:
Several attempts at eradicating P. cinnamomi have been made but were not successful over time. Key management strategies are now constraining the spread of P. cinnamomi and reducing its impact. Of particular importance is preventing its introduction into conservation areas. The application of organic matter and fertilisers has been found to increase microbial antagonism and energy for root regeneration in infected avocado trees (Pegg and Alcorn, 1972: in: Environment Australia, 2001). The chemical phosphite has been found to be useful in treating P. cinnamomi, but its non-target effects are unclear.
The Australian Government Minister for the Environment and Heritage has approved a threat Abatement Plan for Threat Abatement Plan for Dieback Caused by the Root-rot Fungus Phytophthora cinnamomi
Threat abatement plans provide for the research, management, and any other actions necessary to reduce the impact of a listed Key Threatening Process on a threatened species or ecological community. Implementing the plan should assist the long term survival in the wild of the threatened species or ecological community.
The threat abatement plan for dieback caused by Phytophthora cinnamomihas two goals: to protect endangered or vulnerable native species and communities from Phytophthora cinnamomi; and to prevent further species and communities from becoming endangered by reducing the chance of exposure to the pathogen. The objective of the plan is to focus on actions to reduce the threat posed by Phytophthora root rot to native species and ecological communities, its recommendations will also help land managers limit the effects of Phytophthora root rot on Australia's wildflower and forestry (Department of the Environment and Heritage, 2005).
Reduction in native biodiversity: The following native plants are affected by Phytophthora cinnamomi: Epacris purpurascens var. purpurascens, Eucalyptus imlayensis, Genoplesium rhyoliticum, Leionema ralstonii, Tasmannia pupurascens, Westringia davidii and Wollemia nobilis. The southern brown bandicoot Isoodon obesulus and the smoky mouse (see Pseudomys fumeus in IUCN Red List of Threatened Species) are affected by the loss of habitat.
