How Fungi Networks Connect Entire Forests: The Wood Wide Web

Underground fungal networks (mycorrhizae) connect trees and plants across entire forests, forming a biological internet scientists call the Wood Wide Web. These networks allow trees to share nutrients, water, and chemical warning signals. Mother trees nurture seedlings through fungal connections. Dying trees dump their carbon into the network for neighbors. Plants under attack send chemical signals that trigger defensive responses in nearby plants. The discovery has transformed forest management: clear-cutting destroys networks that took centuries to build. Suzanne Simard's research at UBC revealed that forests are cooperative communities, not competitive arenas. The largest known fungal network spans 9 hectares in Oregon's Blue Mountains, estimated at 2,400 years old.
