Protecting Wolves, ferrets, prairie dogs, vultures, etc. (start time: 3:39) How effective are Colorado’s efforts to preserve vulnerable species – wolves, black-footed ferrets, bears, prairie dogs and others? And what ingredients make it possible, including throughout the U.S. and the world, for wild animals and humans to get along when their homes overlap? Today How On Earth host Susan Moran continues her conversation with our guest from last week, wildlife ecologist Dr. Richard Reading, Chair of the Colorado Parks and Wildlife Commission, about Colorado’s most recent Wildlife Action Plan, and about other efforts to protect vulnerable species, ranging from butterflies to vultures. Dr. Reading is also Vice President of Science and Conservation at the Butterfly Pavilion.
