With 909 recognized species of lichens, Great Smoky Mountains National Park (GSMNP) is home to more of these lichenized fungi than any other national park in the United States, as well as nearly half of all species known to occur in eastern North America. There is a great deal of room for scientific exploration, inquiry, and systematic description in the realm of lichenology. In Field Guide to the Lichens of Great Smoky Mountains National Park, Erin Tripp and James Lendemer take on the formidable task of creating an all-in-one resource for Park exploration, including lichen distribution maps, tools for identification, vivid photographs and illustrations, and even field notes from their own research campaigns. In the process, the authors create a touchstone for lichen taxonomy and ecology, and they inspire others—researchers as well as casual observers—to take interest in the incredible biodiversity of the Great Smoky Mountains. Biologists, botanists, visitors to the park, naturalists, and others interested in the flora and fauna of both the southern Appalachians and GSMNP will thoroughly enjoy this lovingly prepared field guide.

Field Guide to the Lichens of White Rocks is a careful examination of the lichens that occur at the ecologically important and lichenologically rich urban outcropping of Fox Hills sandstone known as White Rocks Nature Preserve, located in Boulder County, Colorado.
 
This extensively illustrated field guide presents detailed information on the macroscopic and microscopic features needed to identify species, as well as extensive notes on how to differentiate closely related lichens—both those present at White Rocks and those likely to be found elsewhere in western North America. This guide is one of the only complete lichen inventories of a sandstone formation in North America and covers all constituents including the crustose microlichen biota, traditionally excluded from other inventories. A short introduction and glossary equip the reader with basic information on lichen morphology, reproduction, and ecology.
 
Visitors to White Rocks Nature Preserve must schedule staff-led public tours or set up sponsored research projects through the City of Boulder Open Space and Mountain Parks, and there are many other outcroppings of Fox Hills sandstone across the West, making Field Guide to the Lichens of White Rocks a significant resource for anyone interested in this unique environment. This accessible, user-friendly guide will also be valuable to naturalists and lichenologists around the world as well as educators, conservationists, and land managers concerned with the growing significance of open spaces and other protected urban areas throughout North America.
