This learned and thoroughly objective work is really a must for anyone interested in the history and conservation of trees and woodland. It is full of facts and interest, and as one would expect from a leading academic authority, and active conservationist, properly evidenced. Rackham sketches out the evolution of British trees during the interglacial periods, walks the reader through medieval records, usage and practice, enclosures, war, and conservation. His breadth of knowledge a measure of his passion for the subject. Rackham explains the preference of some trees for certain types of soil, and how pollen taken from soil indicates tree type in ancient woodland. He explains the difference between timber and wood (timber was used for construction, wood, under a certain girth, was in part used for fuel and taxed). Is critical of the response to the Great Storm of 1987, and does not generally favour replanting, over managed woodland, i.e. pollarding, coppicing; and re-wilding. While supporting active conservation work Rackham is critical of over intervention. Rackham died in 2015, but his voice is not yet silent.
