After an 80-year absence, gray wolves have returned to Colorado—how the reintroduction will affect the ecosystem

Gray wolves were reintroduced to Colorado in December 2023, the latest attempt in a decades-long effort to build up wolf populations in the Rocky Mountain states. SciLine interviewed Joanna Lambert, professor of wildlife ecology and director of the American Canid Project at the University of Colorado Boulder, who discussed how and why gray wolf populations declined in the U.S. and the value of reintroducing them to ecosystems in the West.
