I picked this book up the other day. Michael Wojtech does a great job with putting this book together. This soft cover book has some background terms and a great preface of information before getting into the great color photographs of the multiple bark stages the tree goes through over a typical life. There are several that are not covered, but a very good job on those covered. There are also a few species covered that he lacked covering a bark phase. The only BIG downfall is the title, Bark, A field guide to trees of the Northeast, is very misleading. It actually only covers New England, Maine and eastern New York of the USA, versus that traditionally known as the northeast USA.
