The 27 papers in this volume have been developed from presentations made at an international wetlands archaeology conference held in Gainsville, Florida in December 1999. The theme of the conference was: The Significance of the Survival of Organic Materials from Archaeological Contexts. Individuals from seventeen countries spoke about shipwrecks, bog bodies, cenotes of sacrifice, art styles, perishable technologies, palynology, wetlands management, conservation methods, and updates on famous sites. Time periods ranged from the early Pleistocene to a few hundred years ago. As the international composition of the delegates (including a large number of North American scientists) indicates, wetland archaeology has emerged in recent years as a unique discipline facing unique difficulties which are encountered on both sides of the Atlantic.

With the increasingly critical need for innovative approaches that accommodate both wetland protection and economic growth, Our National Wetland Heritage: A Protection Guide, 2nd Edition provides concrete information on local wetland resources, how to set your wetland protection policies, new techniques that have come to the forefront since the first edition, and incentive programs that fairly and effectively involve private landowners.

Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
