WA Peppermint trees across the south west are slowly dying due to unknown causes, which could have a catastrophic effect on the Western Ringtail Possum, a threatened species that depends on the tree for food and shelter.
The decline in Peppermint tree health has become more noticeable in the last few years and affects trees in a range of age groups in different locations in the landscape. Common symptoms include yellowing of the leaves followed by a dying back and eventual death of the whole tree.
The exact cause of the decline is still unknown, but GeoCatch is assisting the Centre for Excellence in Climate Change, Woodland and Forest Health at Murdoch University in its research into the decline and possible treatments.
There are a number of other tree species in our area that are also in decline, including Marri, Flooded Gums and Tuart.
