Seagrasses, a group of about sixty species of underwater marine flowering plants, grow in the shallow marine and estuary environments of all the world's continents except Antarctica. The primary food of animals such as manatees, dugongs, green sea turtles, and critical habitat for thousands of other animal and plant species, seagrasses are also considered one of the most important shallow-marine ecosystems for humans since they play an important role in fishery production. Though they are highly valuable ecologically and economically, many seagrass habitats around the world have been completely destroyed or are now in rapid decline. The World Atlas of Seagrasses is the first authoritative and comprehensive global synthesis of the distribution and status of this critical marine habitat—which, along with mangroves and coral reefs, has been singled out for particular attention by the United Nations Convention on Biodiversity.

Illustrated throughout with color maps, photographs, tables, and more, and written by a large team of international collaborators, this unique volume covers seagrass ecology, scientific studies to date, current status, changing distributions, threatened areas, and conservation and management efforts for twenty-four regions of the world. As human populations expand and continue to live disproportionately in coastal areas, bringing new threats to seagrass habitat, a comprehensive overview of coastal resources and critical habitats is more important than ever. The World Atlas of Seagrasses will stimulate new research, conservation, and management efforts, and will help better focus priorities at the international level for these vitally important coastal ecosystems.

Edmund P. Green heads the UNEP-WCMC's Marine and Coastal Programme and is coauthor with Mark D. Spalding and Corinna Ravilious of World Atlas of Coral Reefs (California, 2001). Frederick T. Short is Research Professor of Natural Resources at the University of New Hampshire and coeditor of Global Seagrass Research Methods (2001).

“Lavishly illustrated...Excellently produced. Acts as an irreplaceable compendium of knowledge about seagrasses.”—Tony Larkum, Times Higher Ed Supplement (thes)

“Overall it paints a gloomy picture of a little appreciated conservation issue...The new report will help alert people worldwide to the dangers of losing seagrasses.”—John Akeroyd, Plant Talk

“This handsome volume is the first global study of seagrasses, their importance to fisheries...and their vulnerability...it’s not really an atlas at all, but a more classy, geography-based reference work.”—Fred Pearce, New Scientist

“An essential purchase...”—J.C. Stachacz, Choice: Current Reviews For Academic Libraries

"Scientists, conservationists, resource mangers and increasingly policy makers are coming to believe that seagrass communities are vitally important ecosystems. This book will make clear the extent of seagrass assemblages, the magnitude of their degradation, and the many adverse consequences of failure to conserve and manage them effectively."—Donald Potts, Professor of Biology at University of California, Santa Cruz

"The World Atlas of Seagrasses will be an invaluable reference: for the novice it will provide a broad background in seagrasses and for the specialist it will give insight into how local problems of seagrass distribution can be explained on a large scale. "—Stephen Bortone, Director, Marine Laboratory, Sanibel-Captive Conservation Foundation
