This book contains papers on the topics of brought together wetland SCientists from all wetland ecology and management, most of continents and provided an opportunity to exchange valuable information on a variety of which were presented at the 2nd International Wetlands Conference in Trebon, Czechoslovakia aspects on the ecology and management of wetlands. (13-22 June 1984). The conference, hosted by the Hydrobotany Department of the Institute of Botany, was organized by the Czechoslovak This volume contains papers that represent aspects of wetland management. Like most Academy of Sciences and the International ecological topics, the papers clearly Wetlands Working Group of the International Association of Ecology (INTECOL) with demonstrate that the science of wetland management is not evenly developed around the cooperation from the SCOPE (SCientific Committee on Problems of the Environment) world. In some areas, wetlands have not even Working Group on Ecosystem Dynamics in been adequately described and there is little Freshwater Wetlands and Shallow Water Bodies, information about the impacts that man is UNESCO Man and the Biosphere (MAB) having on them. In other areas, information on Program, International Society for Ecological wetland ecology and management has developed Modelling, and the International Society for to the point where regulations and laws provide Limnology (SIL). Partial sponsorship for the some protection against development. It is our conference and these proceedings was provided hope this collection of papers will demonstrate by UNESCO (Contract SCjRPj204. 079.

The impetus for this volume was the 2nd International Wetlands Conference which was held in June, 1984 at Trebon, Czechoslovakia. An overview of the worlds wetlands was one of the themes of the conference and it was decided that a useful follow-up would be a publication on the same topic. The initial goal was to cover as many of the worlds wetlands as possible in one volume and to have an emphasis on wetland ecology, biota, classification, and management. Individuals who made presentations at the Trebon confer­ ence were asked to prepare chapters and the editors also solicited other contributions. For a variety of reasons, the initial goal has been difficult to reach, especially coverage of the entire globe, and it has been necessary to publish the contributions in more than one volume. Volume 1 represents the com­ pletion of the first phase of the project and it covers most of the Western Hemisphere, Australia, most of Africa, the Indian subcontinent, the Mediter­ ranean region, and Papua New Guinea. Volume 2 will contain chapters on Western Europe, Northern Europe, Central Europe, most of northern and It is our hope that Volume western Asia, the Middle East, and Indonesia. 2 will appear in the near future and, if possible, a third volume will be published if authors can be secured to cover areas such as the Far East, other parts of the Indo-Pacific region, and New Zealand.

Native Orchids of the United States and Canada is a field guide to the more than 200 native orchids found across the United States and Canada. From rarer species to orchids that even the casual hiker might stumble across, this comprehensive field guide includes: Detailed species accounts with distribution maps, conservation status, and ecological informationVisual keys for readers new to orchid taxonomy, as well as traditional dichotomous keys Vivid photographs and helpful identification tools make Native Orchids of the United States and Canada the definitive resource for enthusiasts of all experience levels to discover this diverse, far-reaching, and colorful family of flowering plants.

The two volumes on “Wetlands as a Natural Resource” in the book series Ecological th Studies (Volumes 190,191) are based on the highlights of the 7 INTECOL International Wetland Conference in Utrecht,25–30 July 2004. This conference brought together about 900 participants from 61 countries,who discussed a very broad range of science-,poli- and management-oriented issues related to wetland ecology and hydrology, wetland conservation and creation, the impact of global change and wetlands as a resource in terms of food,flood protection and water quality enhancement. The participants were from different sectors of society,i. e. ,science and technology (scientists 45%; PhD s- dents 20%),natural resource management (20%) and policy (15%). There were 38 s- posia with invited speakers centered around the nine conference themes. We have given the organizers of these symposia the opportunity to produce one chapter for these books with the integrated content of their symposium. This has resulted in 25 chapters, of which 13 are included in Volume 190 under the heading “Wetlands and Natural Resource Management”and 12 in Volume 191 under the heading “Wetlands: Functi- ing,Biodiversity Conservation and Restoration”. With these books,we had the aim to summarize the most important recent scientific results in wetland science,their applications in wetland and water resource management and their implications for the development of global,national and regional policies in the perspective of the ever-progressing deterioration of natural wetlands and the major impacts that future climate change will have.

This work deals with the distributions of wetlands, the description of wetland types, wetland classification systems, ecological characteristics (primary forcing functions which are responsible for the development and persistence of the wetlands), wetland use and conservation and recommendations on what should be done for each type of wetland.
