PERTH researchers have found two native species are helping each other survive: quenda and tuart trees.
Research from Murdoch and ECU has found fungal spores in marsupials’ droppings are infecting the trees’ roots, increasing their ability to draw moisture and nutrients from the soil.
In recent years, environmental managers and conservationists have been concerned about the trees’ declining health, most notably after the collapse of 500ha of tuart woodland in the heat event of 2011.
The main factors identified include climate change and drying soils.
One of the quendas’ main foods are fungi, whose spores are dispersed in their droppings and then infect tuart roots.
A quenda survey found most sightings in Kalamunda, Gooseberry Hill and Mundaring.
