Beaver, Bison, Horse is an interdisciplinary account of the ecological relationships the Indigenous nations of the Plains had to the beaver, bison, horse, and their habitat prior to contact. Morgan's research shows an ecological understanding that sustained Indigenous peoples for thousands of years, with critical information on how the beaver manage water systems and protect communities from drought in the Northern Great Plains.

Morgan's work is a game-changer.

For the first time in print, her important research now appears with a foreword by James Daschuk, bestselling and award-winning author of Clearing the Plains, and an afterword by Cristina Eisenberg, author of The Carnivore Way and The Wolf's Tooth.
