Pando

Quaking aspen have a remarkable habit: rather than reproducing mainly by seed, they send up new trunks, called ramets, from a shared, spreading root system. Each trunk looks like an individual tree, but genetically they are all one, a single organism cloning itself across the hillside over long spans of time. Pando is the largest known example of this on earth.

Spread across more than a hundred acres, Pando is made of tens of thousands of trunks, all sharing one interconnected root network beneath the soil. Because that root system can persist and regenerate long after individual trunks die, the organism as a whole is thought to be extraordinarily old, with some estimates reaching thousands of years, though its true age is hard to pin down. By total mass it ranks among the heaviest living things ever measured.

Standing in Pando, the clues are subtle but real. All the trunks are the same species, quaking aspen, and because they are genetically identical they tend to leaf out, change color, and drop their leaves in unison, so the whole grove turns green or gold together as if on a single signal. The uniformity that seems ordinary is actually the fingerprint of one shared genome.

The trunks themselves are what most people picture as an aspen forest: pale, chalky bark marked with dark scars, and rounded leaves on flattened stems that catch the slightest breeze. That is the source of the tree's other name, quaking aspen, for the way the leaves tremble and shimmer with a soft rustling sound in even a light wind, a sensory signature of the whole grove.

For all its age and size, Pando faces real threats, and much of the organism is struggling to renew itself. Aspen depend on young shoots growing up from the roots to replace old, dying trunks, but heavy browsing by deer and elk has eaten many of those shoots before they can mature, so parts of the clone are aging without enough young growth to sustain them.

Scientists and land managers have responded by fencing sections of Pando to keep browsing animals out and give new shoots a chance to grow tall, and results have varied across the clone. It is a striking reminder that even one of the oldest and largest living things on earth is fragile, and that its survival now depends in part on careful stewardship. Visitors help by staying on paths and never disturbing the young shoots.

Pando grows in the high plateau country beside Fish Lake, one of the largest natural mountain lakes in Utah, a long, deep body of water rimmed by forest and known for its fishing and its historic lodges. The lake and the surrounding Fishlake National Forest make the area a destination in its own right, so a visit to Pando pairs naturally with time by the water.

The plateau is a high, cool place, and its seasons are pronounced. Summer is mild and green, ideal for exploring the grove and the lakeshore. Autumn is the showstopper, when Pando and the surrounding aspen turn brilliant gold across the plateau for a short run in September. Winter buries the high country in snow, and spring comes late; even in summer, weather at this elevation can turn cold and stormy without much warning.
