3.1 Unearthing the woodwide web

In nature, most trees form fungal connections. The health of the forest depends on fungus – decaying branches and leaf litter are rich with nutrients, and fungi can ferry these back to living plants.

Many fungi form long fungal strands. The individual fungus can colonise quite a large area of the forest floor and this serves as a sort of plumbing system allowing it to conduct carbohydrates, nutrients and water.

They form partnerships with trees through mycorrhizae which infect the tips of the tree roots. The trees are then linked into the fungal underground web.

The tree roots 'team up' with the fungus.
