Deep within Utah's forests lies Pando, an ancient quaking aspen colony. This massive organism, comprised of around 47,000 genetically identical stems, is now 'speaking' through an art and science experiment.
Pando, meaning 'I spread' in Latin, spans 40 hectares and weighs approximately 6,000 metric tons. Estimated to be 12,000 years old, it's considered Earth's largest living organism by mass, with all stems connected by a single root system.
In 2023, sound artist Jeff Rice placed hydrophones into Pando's root system. He captured faint sounds, which transformed into a low rumble during a thunderstorm. Rice believes these sounds originate from millions of leaves vibrating in the wind.
The hydrophones also detected tapping sounds from branches 90 feet away, inaudible in the air. This suggests a connected root system, though further research is needed. Lance Oditt, from Friends of Pando, sees potential for understanding Pando's hydraulic system non-invasively.
Rice emphasizes the use of natural sounds for environmental monitoring. These sounds act as a record of local biodiversity and a benchmark for environmental changes. His recordings of leaves, bark, and the surrounding ecosystem will aid research on water flow, stem connections, insect colonies, and root depth.
Pando is currently deteriorating due to human activities and increased herbivore populations. Researchers fear for Pando's future and the ecosystems it supports. Rice concludes, emphasizing the urgency to listen to the 'Trembling Giant' while it still shares its secrets.
