Book Description
Wetlands and riparian areas between the Rocky Mountains and the Sierra Nevada are incredibly diverse and valuable habitats. More than 80 percent of the wildlife species in this intermountain region depend on these wetlands—which account for less than 2 percent of the land area—for their survival. At the same time, the wetlands also serve the water needs of ranchers and farmers, recreationists, vacation communities, and cities. It is no exaggeration to call water the "liquid gold" of the West, and the burgeoning human demands on this scarce resource make it imperative to understand and properly manage the wetlands and riverine areas of the Intermountain West. This book offers land managers, biologists, and research scientists a state-of-the-art survey of the ecology and management practices of wetland and riparian areas in the Intermountain West. Twelve articles examine such diverse issues as laws and regulations affecting these habitats, the unique physiographic features of the region, the importance of wetlands and riparian areas to fish, wildlife, and livestock, the ecological function of these areas, their value to humans, and the methods to evaluate these habitats. The authors also address the human impacts on the land from urban and suburban development, mining, grazing, energy extraction, recreation, water diversions, and timber harvesting and suggest ways to mitigate such impacts.

Book Description
In this beautifully illustrated guide, two practicing wildlife biologists describe the life histories of forty-five species of ducks, geese, and swans that occur in Texas. For common species and those that breed in the state, each account begins with an interesting fact (such as, “Red-breasted Mergansers have been clocked at over 80 mph, the fastest recorded flight speed for a duck . . .”) and provides information on Texas distribution and harvest, population status, diet, range and habitats, reproduction, and appearance. Exquisite photographs, informative distribution maps, and a helpful source list accompany the species descriptions, and the book offers a glossary and full bibliography for those who want to explore the literature further. With the degradation and disappearance of the inland and coastal habitats that these birds depend upon, the natural history of these waterfowl species provides a vital reminder of the interconnectedness and crucial importance of all wetlands. Birders, biologists, landowners, hunters, outdoor enthusiasts, and all those interested in the health and preservation of our coastal and inland wetland resources will enjoy and learn from this book.
