The "Wood Wide Web": How Trees Communicate and Share Resources
Beneath our feet, trees in a forest are often connected by vast, intricate networks of fungi, forming what scientists call the "Wood Wide Web." These mycorrhizal networks act like an underground internet, allowing trees to exchange nutrients, water, and even warning signals.
Why It’s Fascinating
This discovery revolutionized our understanding of forest ecosystems, revealing that trees are not isolated individuals but interconnected communities. Mother trees can nurture seedlings and even send resources to ailing neighbors through these hidden pathways, demonstrating a profound level of cooperation.
