Melbourne has been inundated with thousands of love letters from across the world addressed to its trees, after the council assigned each one an email address.
The project was intended to allow Australians to report problems with trees in their neighbourhood, providing all 70,000 with an ID number, short bio and contact details.
But instead their inboxes have been swamped with messages which range from the heartwarming to the bizarre - with one anonymous writer telling his favourite tree: "I'm sorry you're going to die soon."
The letters were disclosed to the Atlantic by Melbourne councillor Arron Wood, who has redacted the authors' names to protect their privacy.
"The email interactions reveal the love Melburnians have for our trees," Wood said. "We were surprised and delighted to find that many people all over the world feel the same way."
