The Pando tree, also known as the “Trembling Giant,” is a remarkable symbol of resilience and interconnectedness in nature, located in Utah’s Fishlake National Forest.

This vast clonal colony of approximately 47,000 Quaking Aspen trees, potentially up to 80,000 years old, stands as one of the oldest and most massive living organisms known.

Pando is recognized as a single entity due to the identical genetic markers found in each of its stems.
