@warandpeas One of largest and heaviest living organisms on earth is an aspen forest named Pando, located in the state of Utah. Aspens grow new stems from their roots, so all the trees within an aspen forest can be part of the same original tree. Pando covers 43 hectares (106 acres), weighs 6 million kilograms (13.2 million pounds), and is believed to be tens of thousands of years old. It has 47,000 stems, all connected by a shared root system.
