Gently humorous. Yes. That comes out in the narration too. Even if I tune out for a minute while listening, it pulls me back in shortly. I'm going to replay it at bedtime to get reminders for the book club discussion this week.
I loved the descriptions of how trees communicate, share resources, compete, and cooperate with one another for the long-term benefit of them all. Some trees live longer among others of their kind, and some do fine alone. A forest is not just a collection of separate trees, they are often connected through their roots, fungi and many other things. An old forest is an amazing thing, and it’s not easy to replicate. An old forest is a huge community of trees, plants, fungi, bugs, animals, and wetlands that all work together to help one another thrive. If you introduce a new bug or take away key animals, you change the balance which can lead to drastic and unexpected changes (it can even change the way a river flows).*
One of the last chapters had a section on hazards such as ice and lightening, and how different trees are affected. My husband was walking through the room while I was listening to a section on lightening, and we both said “woah!” at the same time. One Douglas Fir was hit by lightning, and ten other trees connected to it through the roots also died! The water inside conducted the electricity. When an oak tree is hit by lightning, it’s rough bark will show scars, but it will usually survive. Some trees are used in environmental remediation to suck up certain chemicals in the ground water, to keep the chemicals from spreading to other properties.
*Actually, the river flow example might have come from another book by the same author - The Secret Wisdom of Nature. Libby took it back before I could finish it. (Sorry. I waited too long to write this review.)
edit - Or it was from an Elizabeth Kolbert book, or both.
