The cougar is one of the most beautiful, enigmatic, and majestic animals in the Americas. Eliciting reverence for its grace and independent nature, it also triggers fear when it comes into contact with people, pets, and livestock or competes for hunters’ game. Mystery, myth, and misunderstanding surround this remarkable creature. The cougar’s range once extended from northern Canada to the tip of South America, and from the Pacific to the Atlantic, making it the most widespread animal in the western hemisphere. But overhunting and loss of habitat vastly reduced cougar numbers by the early twentieth century across much of its historical range, and today the cougar faces numerous threats as burgeoning human development encroaches on its remaining habitat. When Maurice Hornocker began the first long-term study of cougars in the Idaho wilderness in 1964, little was known about this large cat. Its secretive nature and rarity in the landscape made it difficult to study. But his groundbreaking research yielded major insights and was the prelude to further research on this controversial species. The capstone to Hornocker’s long career studying big cats, Cougar is a powerful and practical resource for scientists, conservationists, and anyone with an interest in large carnivores. He and conservationist Sharon Negri bring together the diverse perspectives of twenty-two distinguished scientists to provide the fullest account of the cougar’s ecology, behavior, and genetics, its role as a top predator, and its conservation needs. This compilation of recent findings, stunning photographs, and firsthand accounts of field research unravels the mysteries of this magnificent animal and emphasizes its importance in healthy ecosystem processes and in our lives.

In the early 1980s, industry and government took a hard look at the economics of extracting oil from vast deposits of shale that lie beneath the western United States. Oil prices subsided, and interest waned. With oil prices spiking and global demand showing no signs of abating, reexamining the economics of oil shale makes sense. In this report, the authors describe oil shale resources; suitability, cost, and performance of new technologies; and key policy issues that need to be addressed by government decisionmakers in the near future.
