As the trees lose their leaves this autumn, consider this. There’s a tree in Utah that has lost its leaves at least 14,000 times.
Nicknamed Pando, it’s a quaking aspen (Populus tremuloides) that’s 14,000(*) years old and the largest known aspen clone. All its trunks come from a single root covering 106 acres. At 6,600 tons its the heaviest known organism on Earth.
