Southwestern Trees
is an easy-to-use, non-technical field guide to the trees found in Arizona and New Mexico, extending to the surrounding areas of southeastern California, southern Nevada, southern Utah, southern Colorado, western Texas, and northern Mexico. Included are descriptions, color photographs, and distribution maps for about 150 coniferous and broadleaf trees of the region, as well as the sometimes treelike species of agaves and yuccas, so characteristic of the desert flora. Also included are a number of species more commonly found as shrubs, but occasionally reaching tree-size in favorable environments.
