Preserved unveils Vermejo—a 558,000-acre living laboratory where rarely seen wildlife behaviors unfold: bears stealing mountain lion kills, microscopic life thriving in seasonal potholes, and animals adapting to a rapidly changing world. In this feature-length documentary, scientists, ranchers, and conservationists reveal how the seemingly impossible has been achieved here, from North America's largest native trout restoration to the return of beaver, elk, and bison. Rich in discovery and layered with human history, Vermejo stands as the pinnacle of conservation in the U.S.—and a bellwether for what’s possible elsewhere.
