Tree identification guide / Old book / Antique book / Field guide

《Trees》 Introduces over 350 species of trees, including the 35 native species found in the UK, along with many common introduced species, variants, and cultivars. The trees are arranged in evolutionary order by family. However, to facilitate comparison of visually similar species, the author sometimes adjusts the order, grouping trees that look alike. The author defines a "tree" as a woody perennial plant that reaches a height of 6 meters or more and has a single trunk. The book places particular emphasis on the characteristics of deciduous trees in "winter," a feature often overlooked in other field guides. It also explains how to estimate a tree's age by measuring its trunk circumference (at 1.5 meters above the ground), providing an example that the circumference of trees growing in open areas increases by an average of 2.5 cm per year.
