Revised and updated 2018. This book divides Maine's landscape into smaller pieces - 'natural communities' and 'ecosystems' - and assigns names to those pieces based on where they fit in the landscape and on their attendant trees, shrubs, wildflowers, and wildlife species. Each of Maine's 104 natural communities has a two page description with color photographs and distribution maps. Introductory material includes a diagnostic key and how this classification fits into a bigger picture for conservation, and appendices include a cross-reference to other classification types and a glossary.
