Reporting Eucalyptus Dieback
Updated: Jul 28
Drought and heatwaves can cause sudden tree dieback, and climate change is increasing these risks across the Peninsula. MPLN is using iNaturalist to map eucalypts and banksias showing signs of decline.
Community sightings will support the Peninsula Dieback Research Project. I encourage you all to record your observations here: MP Dieback Detective · iNaturalist, as well as promote it more widely within your networks.
When entering observations please kindly provide the following:
Clear Photos
Whole tree (from base to crown)
Photo of location context (is it by itself or with others, soil cracking etc)
Close-up of bark or any non-leaf damage (if possible)
Estimated size (e.g. height)
Is the tree still standing? (standing vs. fallen)
Any other comments
Here is an article by researchers at Western Sydney who have been investigating the drivers of Eucalypt Dieback .




Hi, I notice lots of Eucalypt die back since last summer along road sides all around the Mornington Peninsula, especially on the Balnarring Raod and the roads in Main Ridge and Red Hill where large mature Sweet Pittosporum seem to suck out all the moisture out of the ground especially in those hot summer weeks and the last remaining Eucalypts die off. By removing those large environmental weeds the last Eucalypts might be able to be saved.
