I wanted a brief, layperson's guide to redwood trees. How fast do they grow, how much water do they drink in a day, where do they grow, what kinds of animals or birds live in them, etc. Surprisingly, this is a tall order, har har. This book answered some of my questions but not all (maybe how much water do they drink is unanswerable), and it's written with more of a tourist-y style than a descriptive style. But that also means that there are lots of big, full-color photos, there are a few pages about the history of logging and conservation, and there is information and a couple maps some of the parks that have been established to protect them. So that made it handy in ways I had not anticipated.
