The Australian Bureau of Statistics (ABS) takes inspiration from Andy Griffiths’ Treehouse series to highlight some top statistics about trees, to help mark National Tree Day on 30 July.
"Trees play an important role in so many parts of our everyday lives and the ABS has a wealth of information that underlines this," said Peter Meadows from the ABS Environment and Agriculture Accounts Development section.
"From their economic value, to their production of food or use in the home, trees are valuable to us.
"With the Andy Griffiths series of children’s books in mind, the ABS has compiled figures about trees to mark National Tree Day."
