"As a scientist, Loren Smith has made tremendous contributions to our understanding of playa ecology. Through Playas of the Great Plains he makes a further contribution by helping a wider audience understand the uniqueness and importance of these signature features of the Southern Great Plains."

"This is a very significant contribution to the field of wetland ecology. Playa wetlands are very widespread and important, yet there have been few attempts to pull together all of the playa scientific articles and studies into one place. It is especially valuable that this book summarizes many of the recent scientific discoveries about these wetlands."

—Ted LaGrange, Wetland Program Manager, Nebraska Game and Parks Commission

Shallow wetlands that occur primarily in semi-arid to arid environments, playas are keystone ecosystems in the western Great Plains of North America. Providing irreplaceable habitat for native plants and animals, including migratory birds, they are essential for the maintenance of biotic diversity throughout the region. Playas also serve to recharge the aquifer that supplies much of the water for the Plains states. At the same time, however, large-scale habitat changes have endangered playas across the Great Plains, making urgent the need to understand their ecology and implement effective conservation measures.

This book provides a state-of-the-art survey of all that is currently known about Great Plains playa ecology and conservation. Loren Smith synthesizes his own extensive research with other published studies to define playas and characterize their origin, development, flora, fauna, structure, function, and diversity. He also thoroughly explores the human relationship with playas from prehistoric times, when they served as campsites for the Clovis peoples, to today's threats to playa ecosystems from agricultural activities and global climate change. A blueprint for government agencies, private conservation groups, and concerned citizens to save these unique prairie ecosystems concludes this landmark study.
