In 1994 University of Wyoming Botany Professor Dennis Knight wrote a book about Wyoming’s landscapes and some of the challenges they may be facing. Now 20 years later, Knight is joined by other authors to provide an update. The book is called Mountains and Plain: The Ecology of Wyoming Landscapes. We spoke with Knight when he wrote his first book and today he admits to Wyoming Public Radio’s Bob Beck that some of the challenges the state faces today were not on his radar.
