Wolves didn’t just come back to Yellowstone—they sparked a whole new era for the park’s aspen trees. For decades, elk munched every young aspen before it could grow, leaving forests stuck in time. But with wolves keeping elk on the move, aspen saplings finally got their chance. Now, for the first time since the 1940s, new aspen are thriving, bringing back habitats for beavers, birds, and even bears. It’s wild how one change—wolves returning—set off a ripple effect across the entire ecosystem. What do you think: Should more parks try bringing back top predators? #Science #Yellowstone #WildlifeRecovery
