Phytophthora update
Periodic Island wide sampling for Phytophthora was conducted during September by scientists from PlantClinic, the plant disease diagnostic service of Botanic Gardens of Sydney.
This follows sampling visits in April 2024 (107 samples), and in June 2024 (nine samples) which covered the Mt Gower track and summit. It is estimated that 200 additional samples will be taken and analysed following on from this trip.
In addition to the field sampling work, the scientists held community information sessions to outline the nature of the threat of Phytophthora to the unique plant communities found on the Island. This was an opportunity for community members to raise concerns and gain a clear understanding of the importance of sanitary measures to prevent spread of the pathogen.
A total of nine Phytophthora species have been detected on the Island to date. This includes Phytophthora multivora and Phytophthora cinnamomi, which are of noted concern.
An updated Phytophthora management plan for the Island is being prepared. This will include procedures to limit the spread of the pathogen into the protected areas. It will include a strategy that will ensure the protection of these unique plant communities into the future.
How you can help
There are currently no known methods to eradicate Phytophthora, so preventing further spread is the key strategy to reduce impact. Please ensure that you continue to carry out sanitation protocols, including using all boot scrub stations whenever they are encountered, and staying on marked trails.
To protect the unique ecosystems in the Southern Mountains, do not access the Mt Gower track unless accompanied by a licensed guide, or for management reasons, to ensure additional hygiene practices can be implemented.
LHIB are working to install additional sanitising stations beyond the limit of detection.
