During a time when most wild animals are experiencing decline in the face of development and climate change, the intrepid mountain lion—also known as a puma, a cougar, “ghost cat,” and by many other names—has experienced reinvigoration as well as expansion of territory. In Path of the Puma: The Remarkable Resilience of the Mountain Lion (Patagonia Books, October 9, 2018), wildlife biologist Jim Williams celebrates wildlife research and conservation of ghost cats from Canada’s southern Yukon Territory to Tierra del Fuego in Argentina and Chile, exploring what makes this cat, the fourth carnivore in the food chain—just ahead of humans—so resilient and resourceful. Williams writes, “They are beating the odds, and their success provides a remarkable opportunity for wild nature to regain a toehold and to shape possibilities for the persistence of natural systems. They are hope for those of us who believe our future will depend, in large part, on finding the wild.”
