Book Description
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.

The Water-Quality Monitoring Program for the Baltimore Reservoir System, 1981-2007
Author: Michael T. Koterba
Publisher: CreateSpace
ISBN: 9781499171563
Category : Technology & Engineering
Languages : en
Pages : 144
Book Description
The City of Baltimore, Maryland, and parts of five sur- rounding counties obtain their water from Loch Raven and Liberty Reservoirs. A third reservoir, Prettyboy, is used to resupply Loch Raven Reservoir. Management of the water- shed conditions for each reservoir is a shared responsibility by agreement among City, County, and State jurisdictions. The most recent (2005) Baltimore Reservoir Watershed Management Agreement (RWMA) called for continued and improved water-quality monitoring in the reservoirs and selected watershed tributaries. The U.S. Geological Survey (USGS) conducted a retrospective review of the effective- ness of monitoring data obtained and analyzed by the RWMA jurisdictions from 1981 through 2007 to help identify possible improvements in the monitoring program to address RWMA water-quality concerns.

Fundamentals of Geomorphology
Author: Richard John Huggett
Publisher: Routledge
ISBN: 1135281130
Category : Science
Languages : en
Pages : 909
Book Description
This extensively revised, restructured, and updated edition continues to present an engaging and comprehensive introduction to the subject, exploring the world’s landforms from a broad systems perspective. It covers the basics of Earth surface forms and processes, while reflecting on the latest developments in the field. Fundamentals of Geomorphology begins with a consideration of the nature of geomorphology, process and form, history, and geomorphic systems, and moves on to discuss: structure: structural landforms associated with plate tectonics and those associated with volcanoes, impact craters, and folds, faults, and joints process and form: landforms resulting from, or influenced by, the exogenic agencies of weathering, running water, flowing ice and meltwater, ground ice and frost, the wind, and the sea; landforms developed on limestone; and landscape evolution, a discussion of ancient landforms, including palaeosurfaces, stagnant landscape features, and evolutionary aspects of landscape change. This third edition has been fully updated to include a clearer initial explanation of the nature of geomorphology, of land surface process and form, and of land-surface change over different timescales. The text has been restructured to incorporate information on geomorphic materials and processes at more suitable points in the book. Finally, historical geomorphology has been integrated throughout the text to reflect the importance of history in all aspects of geomorphology. Fundamentals of Geomorphology provides a stimulating and innovative perspective on the key topics and debates within the field of geomorphology. Written in an accessible and lively manner, it includes guides to further reading, chapter summaries, and an extensive glossary of key terms. The book is also illustrated throughout with over 200 informative diagrams and attractive photographs, all in colour.

The Maryland Amphibian and Reptile Atlas
Author: Heather R. Cunningham
Publisher: JHU Press
ISBN: 1421425963
Category : Science
Languages : en
Pages : 306
Book Description
The definitive resource for finding, identifying, and conserving Maryland’s amphibians and reptiles. Naturalists, herpetologists, and ecologists alike agree that tracking herpetofauna is a challenging undertaking. Scientists are concerned about the decline of once-familiar species, but evidence has often been too anecdotal to support firm conclusions. To better understand the distribution of amphibians and reptiles in Maryland and forecast species' futures in a time of accelerated environmental threats, conducting a comprehensive statewide survey updating 1970s-era distribution maps seemed ideal. However, this endeavor was of an impossibly ambitious scope for scientists alone to tackle. Enter the Maryland Amphibian and Reptile Atlas project, comprising nearly a thousand dedicated citizen scientists who discovered and recorded the locations of herpetofauna throughout every corner of Maryland. In The Maryland Amphibian and Reptile Atlas, Heather R. Cunningham and Nathan H. Nazdrowicz present the findings of this massive undertaking. This definitive guide combines nearly 160 comprehensive new herpetological maps with historical distribution maps and in-depth species accounts. Color photos illustrate the natural history of the 89 species of frogs, salamanders, turtles, snakes, and lizards that call the state home. Essays discuss historical studies, the effects of Maryland's current climate, geology, and habitat diversity—and the myriad conservation issues these animals face. This richly detailed book represents a triumph of citizen science and the culmination of an intensive research partnership. It will appeal to both amateurs and professionals interested in herpetology, natural history, or ecology, as well as those with a special interest in Maryland's biodiversity.

Blockbusting in Baltimore
Author: W. Edward Orser
Publisher: University Press of Kentucky
ISBN: 0813148316
Category : Social Science
Languages : en
Pages : 256
Book Description
This innovative study of racial upheaval and urban transformation in Baltimore, Maryland investigates the impact of "blockbusting"—a practice in which real estate agents would sell a house on an all-white block to an African American family with the aim of igniting a panic among the other residents. These homeowners would often sell at a loss to move away, and the real estate agents would promote the properties at a drastic markup to African American buyers. In this groundbreaking book, W. Edward Orser examines Edmondson Village, a west Baltimore rowhouse community where an especially acute instance of blockbusting triggered white flight and racial change on a dramatic scale. Between 1955 and 1965, nearly twenty thousand white residents, who saw their secure world changing drastically, were replaced by blacks in search of the American dream. By buying low and selling high, playing on the fears of whites and the needs of African Americans, blockbusters set off a series of events that Orser calls "a collective trauma whose significance for recent American social and cultural history is still insufficiently appreciated and understood." Blockbusting in Baltimore describes a widely experienced but little analyzed phenomenon of recent social history. Orser makes an important contribution to community and urban studies, race relations, and records of the African American experience.
