“…New developments in information technology should continue to assist data Ecological Impact Assessment Jo Treweek and Pete Hankard used to monitor the status and long-term trends in extent and distribution of wetlands in the U.S. is summarized in a paper by Novitzki (1995) on the EMAP Wetlands Program. A key problem is the identification of suitable indicators for different wetland types, not to mention the sheer amount of fieldwork required to visit and survey such a huge number of sites.…”

This is an experimental volume. If it is well received, it may be worthwhile to repeat it on a regular basis, perhaps with a rotating focus (e.g., IA methods one year; other environmental analysis tools another year; developments in adjacent domains in a third year). The editors expressly invite suggestions on how to enhance its usefulness, topics to be covered, and nominations of potential future contributors.Here are selected messages delivered by the papers. The papers are clustered into seven sections according to their focus. Perspective on the FieldThis special paper shares the insights of the man most recognized with crafting the National Environmental Policy Act of 1969 (NEPA) on the motivations for the Act, its intents, and its results.Lynton Caldwell provides perspective on over twenty-five years of NEPA. Neither the declared principles nor the substantive sections of NEPA have been meaningfully implemented. NEPA has been treated as procedural legislation, amplified by the Council on Environmental Quality guidelines which were then elevated to regulations having the status of law in 1978. However, in this guise NEPA has probably had the greatest international impact of any American law. Caldwell summarizes six key lessons from the U.S. experience. OverviewsThis section offers five papers which, by their nature, stretch across our other sections. The first two reflect upon the performance of EA in developed economies, the third presents a contrasting view of recent changes in Chinese EA practice. The fourth paper provides a marvelous overview of the methods-the tools-available to perform EA and IA. "Sustainable development" is a refrain heard often these days, in general and in the papers of this volume. Goodland's paper poses critical environmental sustainability concepts which can guide various EA approaches, especially strategic environmental assessment (SEA), to support sustainable development.The International Study on the Effectiveness of Environmental Assessment is a landmark effort to assess the state of the field involving many participants from a number of countries over the past several years. Directed by Barry Sadler, initiated and supported prominently by the Canadian Environmental Assessment Agency, and facilitated by IAIA, this study reviews EA practice and offers suggestions on improvement. Barry Sadler's paper here presents the organizing concepts behind this assessment.Barry Sadler presents a framework for the evaluation of EA along multiple dimensions. He clarifies the purposes of such evaluation in terms of anticipated improvements in EA practice. The organizing concepts seek to triangulate among policy, practice, and performance. He details principles for evaluation and practical applications.Ralf Buckley focuses on issues in improving the quality of EIA work between the initiation of the process and its consideration in decision-making. He spotlights technical, political, and institutional shortcomings. In particular, needs for EIA improvement include suitable funding for key compon...

/ The management of riverine wetlands, recognized as a major component of biodiversity in fluvial hydrosystems, is problematic. Preservation or restoration of such ecosystems requires a method to assess the major ecological processes operating in the wetlands, the sustainability of the aquatic stage, and the restoration potential of each riverine wetland. We propose a method of diagnosis based on aquatic macrophytes and helophytes. Plant communities are used because they are easy to survey and provide information about (1) the origin of a water supply (i.e., groundwater, seepage, or surface river water) and its nutrient content, (2) effects of flood disturbances, and (3) terrestrialization processes. The novelty of the method is that, in contrast to available typologies, it is based on the interference of gradients resulting from several processes, which makes it possible to predict wetland sustainability and restoration potential. These predictions result from knowledge of the processes involved in terrestrialization, i.e., the influence of flood disturbances, occurrence of groundwater supplies, trophic degree, and water permanency of the habitat during a yearly cycle. The method is demonstrated on five different river systems.
