We tend to think of forests as static. Trees, after all, do not move. But that is a perspective foisted upon us by our limbed existence. Science reporter Zach St. George unmasks this illusion in plain terms: when trees die or new ones sprout, the forest has moved a bit. “The migration of a forest is just many trees sprouting in the same direction.” (p. 2)
There is no shortage of books on trees, but this sounded like such an unusual take on the subject that I was utterly stoked when I learned of The Journeys of Trees. A journalist who delves into the palaeontological record to consider the slow-motion of movement of forests over deep time? Get in here!
This book was originally announced with the subtitle Every Body Leaves a Mark. Next to a clever play on words, it also nicely captures the subject. Patricia Wiltshire is a professor in forensic ecology, botany, and palynology. That last discipline is the study of pollen and spores and is widely used in archaeology, for example for radiocarbon dating. Wiltshire used to be an environmental archaeologist before stumbling into a new career in her fifties when a phone call heralded an unexpected career change. Traces tells that story and is a fascinating first-hand account of her pioneering contributions to forensic science.
