Divided into two parts, Symonds and Chelminski have organized this book in a similar way to The Shrub Identification Book. In the front, they have put together numerous pages of pictorial keys which give a comparison to a small group of similar trees. In the second half, they include master pages where similar trees are place together to highlight the differences. This book makes identifying mystery twigs quick and easy because of the large, detailed photos.
This is not a showy coffee table book and is not pocket sized for easy portability on a hike. But it is a handy reference upon returning home with an unknown tree to identify.
