The Pando forest in Utah, USA, is recognized as one of the oldest and largest living organisms on Earth. Known as "Pando," which translates to "I spread" in Latin, this remarkable forest is not composed of separate trees as it seems, but is actually a single genetic clone of the quaking aspen (Populus tremuloides). Covering more than 106 acres and weighing around 13 million pounds, Pando’s extensive root system has enabled it to thrive for thousands of years, possibly up to 80,000 years. Each aspen tree in Pando acts as a “stem” of the same organism, making it one of the most massive and genetically uniform entities known. When one tree dies, the root system continues to generate new shoots, maintaining a cycle of growth and decay. This ability to regenerate helps Pando withstand natural threats like fire and the death of individual trees. However, human activities, grazing by deer and cattle, and shifting environmental conditions have introduced new challenges. Sin...
