Do trees really communicate with each other?

Trees communication

Yes, we were as confused as you when we heard about this. And to give you a straightforward answer: yes, they do! Today, we’re unraveling the incredible truth about how and why trees talk to each other. 

Trees possess a captivating communication system, a result of millennia of evolution. They communicate with each other through an underground network of fungi, sharing nutrients, resources, and information. 

Imagine a tree within the network of many trees; a neighboring tree faces a threat from a dangerous insect –  In response, the endangered tree emits chemical signals called volatile organic compounds (VOCs) into the air. These compounds act as distress signals, effectively notifying nearby trees to prepare themselves for an impending danger. This sophisticated communication mechanism allows trees to collectively fortify against potential threats, showcasing the complexities of their natural defense strategy.

Now, you might wonder, “How on earth do trees detect these signals?” Well, it’s all thanks to the mutual connection between trees and their mycorrhizal partners (aka fungi). These fungi act as messengers, transmitting the chemical signals from tree to tree.

When a tree is in need, whether it’s facing a pest invasion or lacking nutrients, it sends out a call for help. Other trees, receiving the message, respond by adjusting their own chemical and biological defenses. It’s not just about survival; trees also support each other in times of abundance. Imagine a tree that’s soaking up plenty of sunlight through a process called photosynthesis. It shares the surplus carbon with neighboring trees that might be struggling under the shade.

Now that we’ve established Trees as top-tier communicators, let’s explore why they’ve developed this knack. The simple truth is that it’s all about survival and community—two essential principles crucial for our planet’s well-being!

Strength in Unity

By forming alliances through communication, they can collectively combat threats, whether it’s a pest infestation, a harsh drought, or any other environmental challenge. Unity is their superpower, and the mycorrhizal network is their secret weapon.

Resource Sharing

In the forest, it’s not a cutthroat competition for resources; it’s a collaborative effort. Through communication, trees share nutrients, water, and even information about where these resources are most abundant. It’s a sustainable system where each tree contributes to the ecosystem’s overall health.

Adaptation to Change

The environment is constantly changing, and trees need to adapt to survive. By staying in the loop through communication, trees can adjust based on the collective signals received from the forest.

Ecosystem Harmony

Trees are part of a complex web of life; by communicating, they contribute to the overall harmony of the ecosystem. Whether supporting the growth of neighboring plants or providing habitat for diverse wildlife, trees play a crucial role in maintaining the balance of nature.

As we explored the importance of tree communication, it’s essential to remember that the natural world operates on principles of cooperation and interconnectedness. At, we believe that understanding and appreciating these natural wonders can inspire positive action. So, what can you do to join the conversation? Start by supporting tree planting projects with
