The giant ash is the tallest tree species in Australia and second tallest in the world. It can also lay claim to the title of the tallest flowering plant on earth. Its name - regnans - is from the Latin word regnare, which means ‘to rule’. There are several giant ash trees more than 70 metres high along the Russell Falls track at
Mount Field National Park. These trees are estimated to be 350-450 years old.
