In order to combat the loss of valuable wetland functions and services, federal, state and tribal governments must have the tools to accurately assess and monitor the condition of wetland ecosystems. One particular method of wetland assessment is Floristic Quality Assessment (FQA), which has been growing in popularity throughout the United States since its creation in the 1970s. FQA relies on vegetative indicators of human disturbance to assess the integrity of an ecosystem. FQA calculations are based on Coefficients of Conservatism (C-scores), professionally-assigned scores ranging from 0-10 that denote a local species' tolerance to anthropogenic disturbance. Despite increasing interest in the use of FQA, few studies have thoroughly tested the performance of FQA, especially in New England. We used the Conservation Assessment and Prioritization System (CAPS), a landscape-based, coarse-scale assessment method, as a basis for evaluating FQA's performance in Massachusetts's forested wetlands. Our objective was to use CAPS Index of Ecological Integrity (IEI) scores (a form of generalized stressor gradient) to evaluate the performance of a variety of FQA indices (biological condition gradients), using C-scores from 7 states in the Northeast, and 2 ecoregions in Massachusetts. Based on our calculations of r-squared, and Spearman's rank analysis, we determined that FQA and C-scores have a moderate to weak relationship with the CAPS index of ecological integrity. Of the 12 indices and metrics we tested, the index with the strongest relationship to the IEI stressor gradient was mean Coefficient of Conservatism. Based on this research a number of suggestions are proposed for improving FQA as it applies to wetland assessment.

Recognizing the importance of wetland protection, the Bush administration in 1988 endorsed the goal of "no net loss" of wetlands. Specifically, it directed that filling of wetlands should be avoided, and minimized when it cannot be avoided. When filling is permitted, compensatory mitigation must be undertaken; that is, wetlands must be restored, created, enhanced, and, in exceptional cases, preserved, to replace the permitted loss of wetland area and function, such as water quality improvement within the watershed. After more than a dozen years, the national commitment to "no net loss" of wetlands has been evaluated. This new book explores the adequacy of science and technology for replacing wetland function and the effectiveness of the federal program of compensatory mitigation in accomplishing the nation's goal of clean water. It examines the regulatory framework for permitting wetland filling and requiring mitigation, compares the mitigation institutions that are in use, and addresses the problems that agencies face in ensuring sustainability of mitigated wetlands over the long term. Gleaning lessons from the mixed results of mitigation efforts to date, the book offers 10 practical guidelines for establishing and monitoring mitigated wetlands. It also recommends that federal, state, and local agencies undertake specific institutional reforms. This book will be important to anyone seeking a comprehensive understanding of the "no net loss" issue: policy makers, regulators, environmental scientists, educators, and wetland advocates.

An annotated checklist of the Vascular Flora of the Chicago Region with keys, this book contains notes on local distribution, ecology and taxonomy; a system for the qualitative evaluation of plant communities; a natural divisions' map; and a description of natural plant communities. This comprehensive and detailed treatment employs the revolutionary Coefficient of Conservatism (C values) and Floristic Quality Assessment methodology. "The Swink and Wilhelm tome is one of the very few where I know it will pay to check every species against my [Michigan Flora] manuscript."—Edward Voss

This book describes the underlying water conditions and geologies that support viable riparia, illustrates the ecological characteristics of riparia, and discusses how riparia are used by human cultures as well as how riparia can be used to sustain environmental quality. In recent years riparian management has been widely implemented as a means of improving fisheries, water quality, and habitat for endangered species. This book provides the basic knowledge necessary to implement successful, long-term management and rehabilitation programs. - Treats riparian patterns & processes in a holistic perspective, from ecological components to societal activities - Contains over 130 illustrations and photos that summarize this complex ecological system - Synthesizes the information from more than 6,000 professional articles - Sidebars provide a look into ongoing research that is at the frontiers of riparian ecology and management
