Forest Talk: How Trees Communicate

Trees communicate with us and each other everyday. In this book, you'll learn what trees are saying to us and to each other.

We need trees and forests to help maintain the cycles that keep our air and water healthy for all life on Earth, and trees need us to protect them from destruction and degradation. The work of biologists, ecologists, foresters, and other scientists is key to this protection.

Have you heard the question “If a tree falls in the forest and no one is there to hear it, does it make a sound?” In fact, trees are making sounds all the time. They communicate with us and with each other. If trees are talking in the forest, on our streets, and in our own backyards, we need to listen. Many scientists are doing just that. You can too.
