The Laguna Madre is the only hypersaline coastal lagoon on the North American continent and only one of five worldwide. The lagoon is renowned for its vast seagrass meadows, huge wintering redhead population, and bountiful fishing grounds. In 2000, the Nature Conservancy, whose mission is the conservation of biodiversity through protection of habitat, recognized the need to amass all known information about the Laguna Madre and implement a science-based conservation agenda. From those efforts came the first edition of this book. Now completely revised and updated, this second edition of The Laguna Madre of Texas and Tamaulipas is the culmination of two decades of additional research and continued conservation efforts in the region. Nearly 100 years of literature on the Laguna Madre and surrounding environments has been synthesized here. With 150 figures and illustrations, the book takes a broad and comprehensive look at both the Texan and Tamaulipan Laguna Madre. The value of this book for scientists, conservationists, resource managers, and policy makers involved in the future of the Texas and Mexico coasts is clear. Coastal residents, birders, anglers, and nature lovers who want to learn about and take care of the Laguna Madre will find this to be an indispensable guide.
