Book Description
This manual provides illustrated keys to all leaf and scale lichens known to occur in British Columbia. In total, 327 species are included, while 19 taxa are excluded from earlier accounts of the flora. Accompanying the keys are approximately 350 line drawings. The manual briefly summarizes the ecology, distribution, and frequency status of the province's foliose and squamulose lichens. Each genus account provides a common name, a short description, pertinent references, notes on the derivation of the common name, and notes on global status and distribution, taxonomy, chemistry, and/or similar genera. Each species account provides species and author citation, distribution maps, common names, habit, and lichen distribution in B.C.

Book Description
Nephroma occultum (Cryptic Modest Lichen) is a member of the Nephromataceae (or Peltigeraceae) known to occur in Canada only in the humid, primarily old growth forests of British Columbia. It is a rounded, loosely appressed, foliose (leaf) lichen. This report provides species information such as description, biological and economic significance, distribution, environment and habitat characteristics, population biology, population ecology, land ownership and management responsibility, management practices and experience, evidence of threats to survival, and legal or other formal status. It goes on to offer an assessment of the status for the species and information sources.

Book Description
Boreal felt lichen (Erioderma pedicellatum) is a rare lichen that is listed as critically endangered by the IUCN. On the island of Newfoundland, Canada, the Central Avalon Forest Ecoregion is a hotspot for this species. The population in this region is relatively abundant, providing an opportunity to study its habitat requirements. I used occupied and unoccupied plots (each 5 m radius) to test critical habitat for boreal felt lichen. To ensure I effectively detected lichens in our plots, I developed a decoy lichen experiment to test the detection probability of these lichens. I applied the results from the decoy experiment to the habitat study. Although I could not consider time in the study, I discussed how the shortened lifespan of the host tree may constrain the temporal niche of boreal felt lichen. I identified critical habitat for boreal felt lichen, which will contribute to informed land use to help protect this population.

Book Description
Lichens are a unique form of plant life, the product of a symbiotic association between an alga and a fungus. The beauty and importance of lichens have long been overlooked, despite their abundance and diversity in most parts of North America and elsewhere in the world. This stunning book--the first accessible and authoritative guidebook to lichens of the North American continent--fills the gap, presenting superb color photographs, descriptions, distribution maps, and keys for identifying the most common, conspicuous, or ecologically significant species. The book focuses on 805 foliose, fruticose, and crustose lichens (the latter rarely included in popular guidebooks) and presents information on another 700 species in the keys or notes; special attention is given to species endemic to North America. A comprehensive introduction discusses the biology, structure, uses, and ecological significance of lichens and is illustrated with 90 additional color photos and many line drawings. English names are provided for most species, and the book also includes a glossary that explains technical terms. This visually rich and informative book will open the eyes of nature lovers everywhere to the fascinating world of lichens.

Book Description
Based on the acclaimed reference Lichens of North America, this resource for the classroom, field, and laboratory presents updated and expanded keys for the identification of over 2,000 species of lichens indigenous to the continent, twice the number covered by previous keys. The book includes a glossary illustrated with photographs by Sylvia Duran Sharnoff and Stephen Sharnoff and drawings by Susan Laurie-Bourque, all from the original book. The revised keys are an indispensable identification tool for botanists, students, scientists, and enthusiasts alike.--COVER.

Book Description
A comprehensive, up-to-date review of lichens as biomonitors of air pollution (bioindication, metal and radionuclide accumulation, biomarkers), and as monitors of environmental change (including global climate change and biodiversity loss) in a wide array of terrestrial habitats. Several methods for using lichens as biomonitors are described in a special section of the book.
