First published in 1987, Ralph W. Tiner's A Field Guide to Coastal Wetland Plants of the Northeastern United States soon established itself as the definitive work on its subject. Now Tiner has prepared a revised and expanded edition, broadening the coverage both botanically and geographically. It emphasizes plant identification and includes descriptions of over 700 species and illustrations of approximately 550 species. More tidal wetland types are covered (beaches, rocky shores, and tidal swamps) and the geographic scope extends as far north as Canada's Maritime Provinces.
