I really enjoyed this book. Wohlleben works in forest management, and has written a wonderful book on all the weird ways in which trees adapt to their environments and communicate with each other (using chemical signals, electric signals, etc.). It contains a ton of strange info – for example, apparently some bug-infested trees will chemically signal parasitoids to come eat the bugs that are harming the tree. The author also claims that old trees are more disease resistant because they can communicate with each other about what pathogens have entered the area.
Wohlleben occasionally gets a little sappy and mystical about forestry, but all of his serious claims are either backed by scientific evidence or have a disclaimer that they’re just something he suspects is true.
