Book Description
A remarkably diverse population of bird life, migratory and indigenous, lives in the region known as the Chesapeake Bay country. It is one of the finest locations on the eastern seaboard for observing wild birds. Among the cattail and wild rice, the cordgrass and loblolly, from the countryside north of Baltimore to the windswept beaches of the Atlantic, are the imperiled canvasback, the boat-tailed grackle, the secretive king rail, the fragile egret, and the evasive snowy owl. Illustrated with photographs and line drawings, this book is indispensable to bird watchers and conservationists in the Chesapeake Bay region.

Book Description
This environmental history of America’s largest estuary provides insight into how and why its former productivity and abundant fisheries have declined. The concept of “shifting baselines”—changes in historical reference points used in environmental assessments—illuminates a foundational challenge when evaluating the health of ecosystems and seeking to restore degraded wildlife populations. In this important book, Victor S. Kennedy examines the problem of shifting baselines for one of the most productive aquatic resources in the world: the Chesapeake Bay. Kennedy explains that since the 1800s, when the Bay area was celebrated for its aquatic bounty, harvest baselines have shifted downward precipitously. Over the centuries, fishers and hunters, supported by an extensive infrastructure of boats, gear, and processing facilities, overexploited the region’s fish, crustaceans, terrapin, and waterfowl, squandering a profound resource. Beginning with the colonial period and continuing through the twentieth century, Kennedy gathers an unparalleled collection of scientific resources and eyewitness reports by colonists, fishers, managers, scientists, and newspaper reporters to create a comprehensive examination of the Chesapeake’s environmental history. Focusing on the relative productivity and health of its fisheries and wildlife and highlighting key species such as shad, oysters, and blue crab, Shifting Baselines in the Chesapeake Bay helps readers understand the remarkable extent of the Bay’s natural resources in the past so that we can begin to understand what has changed since, and why. Such knowledge can help illustrate the Bay’s potential fertility and stimulate efforts to restore this pivotal maritime system’s ecological health and productivity.

Book Description
Known for its beauty and bounty, the Chesapeake Bay stretches nearly 200 miles from the mouth of the Susquehanna River to the ocean capes of the Atlantic, its tidal waters enriching the vibrant coastal communities of both Maryland and Virginia. Chesapeake Bay Explorer’s Guide is the perfect reference for visitors who want to know more about the things they see in their visit to the famous estuary, whether they are relaxing on a beach, paddling through a saltmarsh, or watching workboats duck beneath a drawbridge. Explore more than 14,415 miles of shoreline, myriad hiking trails, and scores of wildlife preserves nestled between resort towns and other attractions. This guide provides a concise history of how the Bay was formed, and brief entries with full-color images and easy-to-read descriptions of the flora, fauna, and man-made artifacts found in and around the Bay.

Book Description
This report is part of a series of community profiles produced by the Fish and Wildlife Service to provide up-to-date information on coastal ecological communities of the tidal freshwater marsh community along the Atlantic coast from southern New England to northern Florida. Tidal freshwater marshes occupy the uppermost portion of the estuary between the oligohaline or low salinity zone and nontidal freshwater wetlands. By combining the physical process of tidal flushing with the biota of the freshwater marsh, a dynamic, diverse, and distinct estuarine community has been created. The profile covers all structural and functional aspects of the community: its geology, hydrology, biotic components, and energy, nutrient and biomass cycling.

Book Description
Ecologists have two long-standing ways to study large ecosystems such as lakes, forests, and salt-marsh estuaries. In the first, which G. E. Hutchinson has called the holological approach, the whole ecosystem is first studied as a "black box," and its components are investigated as needed. In the second, which Hutchinson has called the merological approach, the parts of the system are studied first, and an attempt is then made to build up the whole from them. For long-term studies, the holological approach has special advantages, since the general patterns and tentative hypotheses that are first worked out help direct attention to the components of the system which need to be studied in greater detail. In this approach, teams of investigators focus on major func tions and hypotheses and thereby coordinate their independent study efforts. Thus, although there have been waves, as it were, of investigators and graduate students working on different aspects of the Georgia salt-marsh estuaries (personnel at the Marine Institute on Sapelo Island changes every few years), the emphasis on the holo logical approach has resulted in a highly differentiated and well-coordinated long-term study. Very briefly, the history of the salt-marsh studies can be outlined as follows. First, the general patterns of food chains and other energy flows in the marshes and creeks were worked out, and the nature of imports and exports to and from the system and its subsystems were delimited.
