This beautifully illustrated essay collection offers a curious and creative invitation into the world of trees and the words we use to understand them. What is crown shyness, and how could a tree be shy? What is heartwood, and what does it have to do with the heart? So often even our scientific terms are rife with surprising etymologies and images that may reveal as much about us humans and our relationship to nature as they do about the things they describe. Words related to trees and forests are no exception. With a poet’s sensibility, Hannah Fries peels back the layers of these ecological terms, reflecting on their meaning both literally and figuratively, intertwining science and metaphor.
