The “forest floor” of the woodland is deep with mouldy leaves. This particular leaf shows a pattern of mycelium, the thread-like hyphae of fungus.
This woodland is ancient woodland so there is presumably a rich network of mycelia in the soil. On this assumption we have not dusted new tree roots with mycorrhizal fungi.
We have a lot to learn about how mycelia interact with plant roots to exchange nutrients and moisture and pass it on to other plants. The extent of this resource sharing amongst the woodland community is something that scientists are only beginning to discover.
For instance, news of pest invasions is transferred from neighbouring plants, allowing plant hosts to produce repellent compounds.
“Natural internet” is the buzz phrase. The BBC website has an interesting article here:
