The Hidden Alliances of Nature

A tree begins its journey with an extensive root system, deeply anchored beneath the earth. These roots not only stabilize the tree, but they also absorb essential nutrients and water from the soil. However, behind this simple image lies a fascinating network that many are unaware of: the world of mycelium.

Mycelium consists of fine fungal threads, called hyphae, which branch out into vast networks beneath the ground. These networks can stretch for hundreds of kilometers and play a crucial role in the wellbeing of trees. In nutrient-poor soils, they are even indispensable, as mycelium has the exceptional ability to efficiently absorb nutrients from the soil and pass them on to trees.

But that’s not all: Mycelium also stores water and releases it to trees when needed. They prove to be especially useful during periods of drought, supporting the water balance of trees and allowing them to survive even under challenging conditions.

One particularly impressive example of this partnership is mycorrhizal fungi, a type of mycelium that lives in close symbiosis with trees. These fungi not only provide nutrients to trees but also protect them from pathogens by repelling harmful microorganisms. Additionally, they promote root growth and make trees more resistant to environmental stressors such as drought, salinity, and even heavy metal pollution. Mycorrhizal fungi significantly contribute to the health and vitality of trees.

At first glance, this relationship may seem one-sided: Mycelium provides trees with nutrients and water, but what do they get in return? The answer is simple: sugar. Since mycelium cannot perform photosynthesis, they rely on trees to supply essential carbohydrates. These sugars serve as an energy source, allowing mycelium to grow and fulfill its function in the soil.

The symbiosis between trees and mycelium is one of the most fascinating examples of the complex connections in nature. Without this invisible partnership, trees would be far less resilient and would struggle to survive in nutrient-poor soils. It is an impressive interaction between life and survival, hidden beneath our feet.
