Every day, Nadine rides past this swamp mallet on her way to and from work - and she loves to the way the sun changes the colour of the bark depending on the time of day.
That's why she nominated it to be our July Tree of the Month and helped to adorn the tree with a large Tree of the Month medallion.
This tree, which is on Maple Avenue at North Brighton, is one of only 33 swamp mallets across Holdfast Bay, which makes it even more special.
It's also the first of its type to be featured as a Tree of the Month, which started in 2021 as a social media campaign to bring awareness and recognition to our trees on public land.
With care and maintenance, after 20 years, this tree could potentially:
- offset 11,202 kilometres worth of CO2 emitted from the average petrol-powered passenger vehicles
- absorb enough stormwater to fill 1604 bathtubs
- remove an amount of pollution from the air – in gaseous and particulate form – equivalent in weight to 136 smartphones
