Description:This comprehensive and up-to-date reference work is an identification manual covering more than 1100 species of vascular plants that are native or naturalized in aquatic and wetland habitats in the northeastern region of North America, from Newfoundland west to Minnesota and south to Virgina and Missouri. This is a major revision, long-awaited, of Norman Fassett's classic (and much smaller) A Manual of Aquatic Plants. It will interest biologists, resource managers, and environmentalists concerned with the preservation of wetland areas, which are increasingly threatened.
