Book Description
Wetland and Stream Rapid Assessments: Development, Validation, and Application describes the scientific and environmental policy background for rapid wetland and stream assessments, how such assessment methods are developed and statistically verified, and how they can be used in environmental decision-making—including wetland and stream permitting. In addition, it provides several case studies of method development and use in various parts of the world. Readers will find guidance on developing and testing such methods, along with examples of how these methods have been used in various programs across North America. Rapid wetland and stream functional assessments are becoming frequently used methods in federal, state and local environmental permitting programs in North America. Many governments are interested in developing new methods or improving existing methods for their own jurisdictions. This book provides an ideal guide to these initiatives. Offers guidance for the use and evaluation of rapid assessments to developers and users of these methods, as well as students of wetland and stream quality Contains contributions from sources who are successful in academia, industry and government, bringing credibility and relevance to the content Includes a statistically-based approach to testing the validity of the rapid method, which is very important to the usefulness and defensibility of assessment methods

Water Quality Indices
Author: Tasneem AbbasiPublisher: Elsevier
ISBN: 0444543058
Category : Technology & Engineering
Languages : en
Pages : 384
Book Description
This book covers water quality indices (WQI) in depth – it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials. Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water quality and the impact of various factors on it to policy makers, service personnel, and the lay public. Further they are exceedingly useful in the monitoring and management of water quality. With the importance of water and water quality increasing exponentially, the importance of this topic is also set to increase enormously because only with the use of indices is it possible to assess, express, communicate, and monitor the overall quality of any water source. Provides a concise guide to WQIs: their purpose and generation Compares existing methods and WQIs and outlines strengths and weaknesses Makes recommendations on how the indices should be used and under what circumstances they apply
Wetland Indicators
Author: Ralph W. TinerPublisher: CRC Press
ISBN: 1315357070
Category : Technology & Engineering
Languages : en
Pages : 871
Book Description
Understand the current concept of wetland and methods for identifying, describing, classifying, and delineating wetlands in the United States with Wetland Indicators - capturing the current state of science's role in wetland recognition and mapping. Environmental scientists and others involved with wetland regulations can strengthen their knowledge about wetlands, and the use of various indicators, to support their decisions on difficult wetland determinations. Professor Tiner primarily focuses on plants, soils, and other signs of wetland hydrology in the soil, or on the surface of wetlands in his discussion of Wetland Indicators. Practicing - and aspiring - wetland delineators alike will appreciate Wetland Indicators' critical insight into the development and significance of hydrophytic vegetation, hydric soils, and other factors. Features Color images throughout illustrate wetland indicators. Incorporates analysis and coverage of the latest Army Corps of Engineers delineation manual. Provides over 60 tables, including extensive tables of U.S. wetland plant communities and examples for determining hydrophytic vegetation.

With expanded sections on topical issues such as sea level rise, eutrophication, facilitation and the latest approaches to restoration and conservation, the new edition of this prize-winning textbook is a vital resource for wetland ecology courses.
Reconciliation in a Michigan Watershed
Author: Gail Gunst HeffnerPublisher: MSU Press
ISBN: 1609177622
Category : Nature
Languages : en
Pages : 320
Book Description
Like many American urban waterways, Ken-O-Sha has been in decline for nearly two hundred years. Once life-supporting, the waterway now known as Plaster Creek is life-threatening. In this provocative book, scholars and environmentalists Gail Gunst Heffner and David P. Warners explore the watershed’s ecological, social, spiritual, and economic history to determine what caused the damage, and describe more recent efforts to repair it. Heffner and Warners provide insight into the concept of reconciliation ecology, as enacted through their group, Plaster Creek Stewards,who together with community partners refuse to accept the status quo of a contaminated creek unfit for children’s play, severely reduced biological diversity, and environmental injustices. Their work reveals that reconciliation ecology needs to focus not only on repairing damaged human–nature relationships, but also on the relationships between people groups, including Indigenous North Americans and the descendants of European colonizers.
Mid-Atlantic Freshwater Wetlands: Advances in Wetlands Science, Management, Policy, and Practice
Author: Robert P. BrooksPublisher: Springer Science & Business Media
ISBN: 1461455960
Category : Science
Languages : en
Pages : 498
Book Description
The lands and waters of the Mid-Atlantic Region (MAR) have changed significantly since before the 16th century when the Susquehannock lived in the area. Much has changed since Captain John Smith penetrated the estuaries and rivers during the early 17th century; since the surveying of the Mason-Dixon Line to settle border disputes among Maryland, Pennsylvania, and Delaware during the middle of the 18th century; and since J. Thomas Scharf described the physiographic setting of Baltimore County in the late 19th century. As early as 1881, Scharf provides us with an assessment of the condition of the aquatic ecosystems of the region, albeit in narrative form, and already changes are taking place – the conversion of forests to fields, the founding of towns and cities, and the depletion of natural resources. We have always conducted our work with the premise that “man” is part of, and not apart from, this ecosystem and landscape. This premise, and the historical changes in our landscape, provide the foundation for our overarching research question: how do human activities impact the functioning of aquatic ecosystems and the ecosystem services that they provide, and how can we optimize this relationship?
Plant Ecology
Author: Paul A. KeddyPublisher: Cambridge University Press
ISBN: 1316727858
Category : Science
Languages : en
Pages : 629
Book Description
Presenting a global and interdisciplinary approach to plant ecology, this much-awaited new edition of the book Plants and Vegetation integrates classical themes with the latest ideas, models, and data. Keddy draws on extensive teaching experience to bring the field to life, guiding students through essential concepts with numerous real-world examples and full-colour illustrations throughout. The chapters begin by presenting the wider picture of the origin of plants and their impact on the Earth, before exploring the search for global patterns in plants and vegetation. Chapters on resources, stress, competition, herbivory, and mutualism explore causation, and a concluding chapter on conservation addresses the concern that one-third of all plant species are at risk of extinction. The scope of this edition is broadened further by a new chapter on population ecology, along with extensive examples including South African deserts, the Guyana Highlands of South America, Himalayan forests and arctic alpine environments.
