How Trees Communicate Using an Underground Network
Forests have a secret internet—and it’s made of fungi
What if trees could talk to each other? Turns out, they do—but not through sound. Recent discoveries show that trees are connected by a vast underground fungal system known as the mycorrhizal network. This hidden world allows trees to communicate, share resources, and even warn one another of threats. It’s nature’s original internet—and it’s smarter than we thought.
The science behind the Wood Wide Web
This underground network is formed by mycorrhizal fungi, which attach to the roots of trees and plants. In return for sugars from the tree, the fungi extend their hyphae to absorb water and nutrients. But these fungi don’t just benefit individual trees—they connect entire forests in a kind of plant internet.
- Warning signals – Trees attacked by pests release chemicals into the network, alerting nearby trees to ramp up defenses.
- Resource sharing – Older trees have been seen transferring nutrients to younger ones through the network.
More mind-blowing plant behavior
Plants might not have brains, but they clearly react and adapt to their environment. Through chemical signaling and this underground web, forests function more like communities than collections of individuals.
- Mother trees – Large, old trees act as hubs, helping coordinate the health of nearby saplings.
- Fungal matchmaking – Fungi choose which plants to connect based on need, strength, or location.
- Stress detection – The network detects drought, toxins, and overpopulation, prompting tree responses.
Why this matters in the modern world
Understanding the forest network has major implications. Logging or planting trees without considering these fungal links can damage entire ecosystems. Protecting “mother trees” is now seen as crucial for forest regeneration and climate stability.

Conclusion
Trees might not speak like we do, but they listen, respond, and care for each other in profound ways. The mycorrhizal network shows us that even in silence, nature has its own language.
