Trees are not solitary plants, instead they are part of a vast and complex network, which is capable of sharing nutrients, water and warning surrounding trees about dangers such as damaging insects or changes in atmospheric conditions.
This fun little video is a great demonstration of the interconnected nature of trees, and how they actually nurture offspring and other trees within the community!
Mycorrhizal fungi describes a symbiotic relationship between fungus and the roots of vascular plants (such as trees). Tiny fungus tendrils (called mycelium) create a vast web through the soil, which can spread for miles. These fine hair-like tendrils are able to extract nutrients and water from a wide radius, which allows vascular plants such as trees to access these nutrients in exchange for providing the fungus with sugars.
