Thanks to the research made out by the forest ecologist Suzanne Simard, it was discovered that the plants interact and communicate through an underground network of fungi, which unite the plants with the surrounding ecosystem.
Simard, of the University of British Columbia, in Canada, explains that it is a symbiosis in which plants contribute to the development and mutual growth resulting in forest biodiversity in different regions of the world. This discovery was made during the microscopic observation of small bands of white and yellow fungi found in the forest floor, where they managed to see how the fungi are connected to the roots of the tree and thanks to that connection, they manage to exchange carbon, water and nutrients.
In the words of Simard, "The big trees provide subsidies to the youngest through this network of mushrooms. Without this help, most seedlings would not develop." In other words, the oldest, most developed and largest trees are" mother plants" that are responsible for the management of the resources of a community of plants through the fungi: "This connection is so strong that when a tree of this size is cut, the survival rate of the youngest members of the forest or jungle is drastically reduced. The connection between the plants is comparable to the synapses of human neurons."
