Something extraordinary is happening in the heart of the forest - a constant exchange of messages that are conveyed in a language that is far beyond human perception. Trees and plants communicate with each other in ways that are often hidden from us. In this blog post, we would like to introduce you to the fascinating world of plant communication.
Communication among plants occurs mainly in two ways: through the root system and through chemical messengers in the air. Each of these communication pathways has its own complexity and plays a crucial role in the forest ecosystem.
The roots of a tree are not just there to absorb nutrients and anchor themselves. There is a widely branched network beneath the ground that runs through forests and plant landscapes. The so-called mycorrhizal network, a symbiotic association between fungi and plants, serves as a kind of "Internet of the forest". Through this network, trees and plants can exchange nutrients and information in order to support and warn each other.
But how does communication through the air work? Trees and plants emit chemical signals known as volatile organic compounds (VOCs). These chemicals can be picked up by neighboring plants, which can then activate their own defense mechanisms. For example, a tree that is being attacked by pests can emit VOCs that warn neighboring trees and give them time to activate their own defense mechanisms.
But communication doesn't stop at warding off pests. Some studies have shown that plants are also able to influence the growth and development of other plants through chemical messengers known as allelochemicals. These substances can inhibit or promote the growth of competing plants, depending on what is most beneficial for the survival of the emitting plant.
This constant dialogue between trees and plants shows how interconnected and complex life in our forests is.
So if we plant trees locally in the Sauerland and push forward our reforestation project, WALDEMAR can see our activity. Nice to know!
By trying to understand the language of plants, we can learn how to better protect and care for our forests and environment. The trees and plants are constantly communicating with each other - it is up to us to listen.
