Reading is often considered a secondary practice to gaining valuable familiarity with trees, although for many people, it is the primary and sometimes the only means of acquiring arboreal knowledge. In this chapter, I explore poetic, scientific, and artistic approaches to reading trees. I demonstrate that the concept of reading encompasses a variety of methods, including reading about trees, using trees as navigational tools, the anthropological art of noticing (Anna Tsing), arboreal cryptography and translations in dendrochronology (Valerie Trouet), and artistic interventions into the readability of texts and environments (Katie Holten). Following debates about literary texts’ suitability as sources in nature writing and storytelling’s effectiveness in popular science writing, this chapter navigates the interdisciplinary and discursive challenges that trees pose to humans who write and read, from poets and historians to foresters and dendrochronologists. This enables readers to participate in negotiating what a tree is.
