The Niobrara

"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."--book jacket.
