The concept of "wilderness" also took on a new meaning; Leopold no longer saw it as a hunting or recreational ground, but as an arena for a healthy biotic community, including wolves and mountain lions. In 1935, he helped found the Wilderness Society, dedicated to expanding and protecting the nation's wilderness areas. He regarded the society as "one of the focal points of a new attitude—an intelligent humility toward Man's place in nature." Science writer Connie Barlow says Leopold wrote eloquently from a perspective that today would be called Religious Naturalism.
