The Hidden Life of Trees by Peter Wohlleben (2015)
I really did not know that trees can communicate with each other, warn each other about predators, help each other by providing nutrients to the weak, and that the massive root structures are responsible for a lot of this. I know I have heard of huge fungi growing underground, and the fungi have an important role in forests, but the roots! I just feel I am constantly fighting with the roots of the many trees on my property, when I try to work on a flower bed - often a solid mass of roots. One of the biggest questions I had while reading this was - how in the world did they measure all this and get the data, as trees function much more slowly than we do - and more slowly than the Ents in Lord of the Rings. Another question I had, and which might have been answered in one of the chapters I did not read - What happens to the roots and fungi when a forest is cleared? Do they just rot away? I assume for a while they provide fertile soil for crops, but then with erosion and decay, it probably is much less so.
