    What is the regional distribution of this book? I live in San Jose, CA and am anxious to get a book that will help me ID the trees in this region. If there are sufficient numbers of trees found in CA in this book, I would seriously consider a purchase. I love the didactic style of your books which I find lacking in other guides.

      Hi Dave, The Tree guide covers all of the native trees of California, and most of the common exotics. From the Bay area southwards along the coast the climate is mild enough to support and incredible diversity of cultivated trees, so in San Jose you will see some planted trees in town that are not in the guide, but out in a natural area all the species should be in the book. Hope that helps.
      Best, David

    Just putting in another two cents: I love your tree guide and would definitely buy an app for my android phone. Hope you’ll consider creating one.

    Just wanted to put in another vote for an iOS app for this book. I rarely carry a printed field guide anymore.
