The Atchafalaya River Basin

In this comprehensive, one-volume reference, Nature Conservancy scientist Bryan P. Piazza poses five key questions: —What is the Atchafalaya River Basin? —Why is it important? —How have its hydrology and natural habitats been managed? —What is its current state? —How do we ensure its survival? For more than five centuries, the Atchafalaya River Basin has captured the flow of the Mississippi River, becoming its main distributary as it reaches the Gulf of Mexico in south Louisiana. This dynamic environment, comprising almost a million acres of the lower Mississippi Alluvial Valley and Mississippi River Deltaic Plain, is perhaps best known for its expansive swamp environments dominated by baldcypress, water tupelo, and alligators. But the Atchafalaya River Basin contains a wide range of habitats and one of the highest levels of biodiversity on the North American continent. Piazza has compiled and synthesized the body of scientific knowledge for the Atchafalaya River Basin, documenting the ecological state of the basin and providing a baseline of understanding. His research provides a crucial resource for future planning. He evaluates some common themes that have emerged from the research and identifies important scientific questions that remain unexplored.

Louisiana’s Atchafalaya River Basin is one of the most dynamic and critical environments in the country. It sustains the nation’s last cypress-tupelo wetland and provides a habitat for many species of animals. Endowed with natural gas and oil fields, the basin also supports a large commercial fisheries industry. Perhaps most crucial, it remains a primary component of the plan to control the Mississippi River and relieve flooding in New Orleans, Baton Rouge, and other communities in the lower river valley. The continuing health of the basin is a reflection not of nature, but of the work of the U.S. Army Corps of Engineers. With levee building and clearing in the nineteenth century and damming, dredging, and floodway construction in the twentieth, the basin was converted from a vast forested swamp into a designer wetland, where human aspirations and nature maintained a precarious equilibrium. Originally published by the U.S. Army Corps of Engineers primarily for internal distribution, this environmental and political history of the Atchafalaya Basin is an unflinching account of the transformation of an area that has endured perhaps more human manipulation than any other natural environment in the nation. Martin Reuss provides a new preface to bring us up-to-date on the state of the basin, which remains both an engineering contrivance and natural wonder.

In the early 1970s, two idealistic young people -- Gwen Carpenter Roland and Calvin Voisin -- decided to leave civilization and re-create the vanished simple life of their great-grandparents in the heart of Louisiana's million-acre Atchafalaya River Basin Swamp. Armed with a box of crayons and a book called How to Build Your Home in the Woods, they drew up plans to recycle a slave-built structure into a houseboat. Without power tools or building experience they constructed a floating dwelling complete with a brick fireplace. Towed deep into the sleepy waters of Bloody Bayou, it was their home for eight years. This is the tale of the not-so-simple life they made together -- days spent fishing, trading, making wine, growing food, and growing up -- told by Gwen with grace, economy, and eloquence. Not long after they took up swamp living, Gwen and Calvin met a young photographer named C. C. Lockwood, who shared their "back to the earth" values. His photographs of the couple going about their daily routine were published in National Geographic magazine, bringing them unexpected fame. More than a quarter of a century later, after Gwen and Calvin had long since parted, one of Lockwood's photos of them appeared in a National Geographic collector's edition entitled 100 Best Pictures Unpublished -- and kindled the interest of a new generation. With quiet wisdom, Gwen recounts her eight-year voyage of discovery -- about swamp life, wildlife, and herself. A keen observer of both the natural world and the ways of human beings, she transports readers to an unfamiliar and exotic place.
