In the very heart of the forest, something extraordinary happens – a constant exchange of messages conveyed in a language far beyond human perception. Trees and plants communicate with each other in a way that often remains hidden from us. In this blog post, we would like to introduce you to the fascinating world of plant communication.
Communication among plants mainly takes place in two ways: through the root system and by chemical messengers in the air. Each of these communication paths has its own complexity and plays a crucial role in the forest’s ecosystem.
The roots of a tree are not only for nutrient uptake and anchoring. Beneath the ground stretches a far-reaching network that runs through forests and plant landscapes. The so-called mycorrhiza network, a symbiotic union between fungi and plants, serves as a kind of “internet of the forest.” Through this network, trees and plants can exchange nutrients and information to support and warn each other.
But how does communication through the air work? Trees and plants send out chemical signals known as volatile organic compounds (VOCs). These messengers can be taken up by neighbouring plants, which can then activate their own defence mechanisms. For example, a tree infested by pests can emit VOCs that warn nearby trees and give them time to activate their own defences.
But communication does not stop at pest defence. 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 favourable 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 when we plant trees locally in the Sauerland and advance our reforestation project, WALDEMAR can perceive our activity. Somehow 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.
