Nearly 200 years after bison were hunted to extinction in northern Mexico, 47 were reintroduced in 2025, and are now helping prevent wildfires and regenerate their lost ecosystem

In a remarkable conservation effort, 47 American bison have been reintroduced to Mexico's Cuatrociénegas region after vanishing for nearly 200 years. Now residing in the El Santuario Reserve in Coahuila, these magnificent creatures act as vital ecosystem engineers. Their grazing and movements are expected to rejuvenate the local landscape.
