The first fruits of Greek botany.

Theophrastus of Eresus in Lesbos, born about 370 BC, is the author of the most important botanical works that have survived from classical antiquity. He was in turn student, collaborator, and successor of Aristotle. Like his predecessor he was interested in all aspects of human knowledge and experience, especially natural science. His writings on plants form a counterpart to Aristotle’s zoological works.

In the Enquiry into Plants Theophrastus classifies and describes varieties—covering trees, plants of particular regions, shrubs, herbaceous plants, and cereals; in the last of the nine books he focuses on plant juices and medicinal properties of herbs. This edition is in two volumes; the second contains two additional treatises, On Odours and Weather Signs.

In De causis plantarum Theophrastus turns to plant physiology. Books 1 and 2 are concerned with generation, sprouting, flowering and fruiting, and the effects of climate. In Books 3 and 4 Theophrastus studies cultivation and agricultural methods. In Books 5 and 6 he discusses plant breeding; diseases and other causes of death; and distinctive flavors and odors. The Loeb Classical Library edition is in three volumes.

Theophrastus’ celebrated Characters is of a quite different nature. This collection of descriptive sketches is the earliest known character-writing and a striking reflection of contemporary life.

The west is full of magnificent trees: mighty spruces, towering cedars, and stout firs. We are used to appreciating trees during their glory years, but how often do we consider what happens to a tree when it dies? We’ve all seen driftwood on the beach. But how many people have truly looked at it and appreciated its ecological role?
 
Ellen Wohl has thought about these questions, and In Dead Wood, she takes us through the afterlife of trees, describing the importance of standing and downed dead wood in forests, in rivers, along beaches, in the open ocean, and even at the deepest parts of the seafloor. Downed wood in the forest provides habitat for diverse plants and animals, and the progressive decay of the wood releases nutrients into the soil. Wood in rivers provides critical habitat for stream insects and fish and can accumulate in logjams that divert the river repeatedly across the valley floor, creating a floodplain mosaic that is rich in habitat and biodiversity. Driftwood on the beach helps to stabilize shifting sand, creating habitat for plants and invertebrates. Fish such as tuna congregate at driftwood in the open ocean. As driftwood becomes saturated and sinks to the ocean floor, collections of sunken wood provide habitat and nutrients for deep-sea organisms. Far from being an unsightly form of waste that needs to be cleaned from forests, beaches, and harbors, dead wood is a critical resource for many forms of life.
 
Dead Wood follows the afterlives of three trees: a spruce in the Colorado Rocky Mountains that remains on the floodplain after death; a redcedar in Washington that is gradually transported downstream to the Pacific; and a poplar in the Mackenzie River of Canada that is transported to the Arctic Ocean. With these three trees, Wohl encourages readers to see beyond landscapes, to appreciate the ecological processes that drive rivers and forests and other ecosystems, and demonstrates the ways that the life of an ecosystem carries on even when individual members of that system have died. Readers will discover that trees can have an exceptionally rich afterlife—one tightly interwoven with the lives of humans and ecosystems.
