Far to the south of Arizona’s sprawling metropolises, a rolling savanna of grass, oak, and mesquite rises above the surrounding deserts. The Sonoita Plain is a basin of a thousand square miles bracketed by mountains, a land once the domain of cowboys that is now more and more the focus of exurban development. These southwestern grasslands are both typical of and distinct from those of the Great Plains—similarly shaped by drought, grazing, and fire, but with a different flo...

Fear of bears seems almost to be part of what it is to be human. Our species emerged out of the depths of time into a world already populated by these great carnivores. Before we mastered iron and later developed firearms, we had few defences against bears—only watchful caution and elaborate ceremonies and sacrifices to ward off fear.Where human populations grow, bears have traditionally dwindled or disappeared. But when we return to the wild, to places where bears still survive, a...

Beginning in the late 1980s, a series of improbable bark beetle outbreaks unsettled iconic forests and communities across western North America. An insect the size of a rice kernel eventually killed more than 30 billion pine and spruce trees from Alaska to New Mexico. Often appearing in masses larger than schools of killer whales, the beetles engineered one of the world's greatest forest die-offs since the deforestation of Europe by peasants between the eleventh and thirteenth centuries.

Beavers are the great comeback story—a keystone species that survived ice ages, major droughts, the fur trade, urbanization and near extinction. Their ability to create and maintain aquatic habitats has endeared them to conservationists, but puts the beavers at odds with urban and industrial expansion. These conflicts reflect a dichotomy within our national identity. We place environment and our concept of wilderness as a key touchstone for promotion and celebration, while devoting signifi...

Wolves have become a complicated comeback story. Their tracks are once again making trails throughout western Alberta, southern British Columbia and the northwestern United States, and the lonesome howls of the legendary predator are no longer mere echoes from our frontier past: they are prophetic voices emerging from the hills of our contemporary reality.Kevin Van Tighem’s first RMB Manifesto explores the history of wolf eradication in western North America and the species’ recent...

Until about 13,000 years ago, North America was home to a menagerie of massive mammals. Mammoths, camels, and lions walked the ground that has become Wilshire Boulevard in Los Angeles and foraged on the marsh land now buried beneath Chicago's streets. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction...
