Lichens above Treeline: A Hiker's Guide to Alpine Zone Lichens of the Northeastern United States

This is the first guide to identifying the lichen species that grow in the White Mountains, Green Mountains, Adirondacks, and nearby alpine and rugged coastal environments. Based on extensive field work and research, the book explains the fascinating biology of lichens, which thrive where other plants can’t survive, and provides full-color magnified photographs, a color bar for identification, scientific and common names, descriptive notes and information on growth forms, substrate, reproduction and comparisons to similar species, as well as references, a glossary, and a bibliography.
