Fungi form a large underground network in our forest soils that has important ecological functions for the growth and health of the forest ecosystem. In this solo-episode with Judith Lundberg-Felten, we take a deep dive underground and explore

- How old beneficial fungus-plant interactions, also called mycorrhiza, are.

- How trees and fungi can benefit from entering into a symbiotic (beneficial) relationship.

- Why they matter for the forest even today.

- What the risk of deforestation is for the forest ecosystem.
