Yes, You are right Pando, also known as the Trembling Giant, is a massive grove of quaking aspen trees (Populus tremuloides) located in Utah, USA. While it consists of multiple trees, they are genetically identical and connected through a common root system, making Pando the largest living organism on Earth. Researchers have been studying Pando using various methods, including the use of sound. Sound monitoring allows scientists to gain insights into the health, vitality, and interactions of the trees within the grove. By analyzing the sounds emitted by Pando, researchers can detect signals related to growth patterns, stress responses, and other aspects of the tree's biology.
