Although its history is etched on canyon walls reaching back twenty million years, the Niobrara is very much a river of today. Stretching 535 miles from its headwaters to the Missouri River, it is one of Nebraska's least altered waterways and is designated as a national scenic river. Its waterfalls and wildlife make it a haven for outdoor enthusiasts, but pressures from development still threaten its scenic and ecological wonders.This first book-length study of the Niobrara is a comprehensive look at an ecological treasure. Paul A. Johnsgard reviews the river's history from its geologic past through prehistoric settlement to the present and highlights its historical and biological features.Writing from this crossroads of eastern and western species, Johnsgard also describes the Niobrara's varied plants and animals, providing extensive information on bird populations. He offers portraits of sixteen species of special conservation concern, such as the black-tailed prairie dog and the olive-backed pocket mouse. Drawings by Johnsgard, information tables on various species, plus site lists make the book an invaluable reference. It conveys the Niobrara's value as a recreational and scientific resource to help visitors better appreciate this riparian paradise while offering specialists an unimpeachable guide to its scientific riches. The Niobrara includes chapters by Jon Farrar and Duane Gudgel.
