Pando is a single quaking aspen in Utah that has cloned itself into roughly 47,000 genetically identical trunks across 106 acres, making it one organism weighing nearly 6,000 tonnes and likely dating back thousands of years, to around the end of the last ice age
In a corner of Utah's Fishlake National Forest, 47,000 white-barked aspen trunks share a single root system and a single genome — making Pando the heaviest known living organism on Earth, possibly older than the last ice age, and quietly being eaten out of existence by mule deer.
