Trees communicate in ways we don’t entirely understand. They form a forest society.
That’s the big them from the 2021 book Finding the Mother Tree: Discovering the Wisdom of the Forest Book by Suzanne Simard. She spent a career in this work, and was long sidelined as on the fringes of research. But credibility has come her way.
Older trees appear to know which other trees are their direct descendants, to which they send more nutrients too, though they share with all. Her work is all around “Mychorzzal fungal network”
It got deeper than I needed to get on the topic but others might appreciate it. As she writes “This is not a book about how we can save the trees. This is a book about how the trees might save us.”
