Reasons to study trees run from the scientific to the cultural, from the economic to the aesthetic. But reasons are hardly needed: man’s dependence on trees, directly and indirectly, goes back to those distant times when the human species was first making its mark, and our dependence continues to this day. This field guide to the major native and introduced species north of Mexico identifies nearly 600 species in 76 families. Each listing includes a family overview, common and scientific names for each species, distinguishing characteristics, range, environmental niche, whether the species is native or introduced, and reproduction. Scientifically accurate and artistically exquisite, this guide will allow an appreciation of trees to take root in your students’ minds. Index. 280 pp., softcover.
