Koch, Melissa. Forest Talk: How Trees Communicate. Minneapolis, MN: Twenty-First Century Books, Lerner Publishing Group, Inc., 2019. An introduction to trees, how they live (and talk to each other), how we humans depend on them (for, well, everything,), and what we can do to save tree populations from disappearing through human destruction. Everything is connected. The communication part explains how trees communicate belowground through a combination of fungi and roots called a mycorrhizal network. So very cool. Glossary, bibliography, and supporting photographs included. Ages: 12+. For a narrative nonfiction introduction for the preschool and kindergarten set, try Listen to the Language of Trees (Tera Kelley; illus. Marie Hermansson, Naperville, IL: Dawn Publications, 2022). For teenagers and grownups, be sure to sink into Peter Wohlleeben’s The Hidden Life of Trees: What They Feel, How They Communicate (Vancouver: Greystone Books, Ltd., 2016).
