Could the book be better? Well, the obvious answer is always yes, I suppose, but I don't know how. Would some kind of a 'flow-chart' for identifying specimens improve this edition? Well, there is one, created quiet simply in the way the book is organized; refer to the "How to Use this Guide" section in the front. I won't claim to be a connoisseur of guidebooks, but this one has worked very nicely for me for several years and I recommend it without hesitation.
I got the book because it had the Audobon name, and it included some sharp color photos. I should have got the Peterson guide instead.
What the Audobon book is missing is an algorithm or process to identify an unknown tree (they call this "differential diagnosis" in medicine). I was expecting something like: "If it has 5 needles per cluster turn to page 45, if it has grey bark turn to page 64, etc" until you pinpoint your tree.
I would even be happy if it had some illustrations like Silbeys bird book ... with arrows pointing to the discriminating features that distinguish the tree from similar trees.
But in the Audobon book, the reader is expected to browse thru dozens of photos and try to match your tree to the photo. But SURPRISE, the photos of similar trees all look alike and what then? You are expected to browse the the dense textual (!) descriptions and flip back and forth reading minutae like "two white strips on the undersides of the needles"
How about some color illustrations? How about a list of similar trees a given tree is often confused with? How about a handful of distinguishing characteristics of each tree?
Try Petersons book instead!
