Book excerpt: Building upon existing classification systems of natural environments, this visually-oriented guide--from the Arctic Circle to Central America--advocates a universal, biogeographic standard for inventorying regional habitats as now used by the Environmental Protection Agency and some state agencies. The separate digitized map, dramatically unfolding to 42x42", is color-coded to depict gradients in moisture and temperature: factors which delimit vegetation and adaptations by flora and fauna.
