This is one of those little guidebooks you might pick up at a hotel or visitor center while on vacation, which is what I did. As such things go, it's pretty good. There's lots of color pictures of the trees, and the text is decent and gives you a little history with your botany, as it explains which non-native trees were introduced when and what people have used them for. Mostly, it did its job of answering the question "What tree is that?" well enough, at least when I remembered to bring it with me. ( )
