"The Secret Life of Trees" explores the complex relationships and communication systems among trees in forests. Trees are not solitary beings; they interact with each other through a network of roots and fungi, often referred to as the Wood Wide Web. This underground network allows them to share nutrients and information, helping them thrive in their environment. Additionally, trees communicate through chemical signals released into the air and soil. When under threat from pests or disease, they can send distress signals to nearby trees, prompting them to bolster their defenses. This intricate web of connections highlights the importance of trees in maintaining healthy ecosystems.
