Yellowstone's Wolf Reintroduction: Aspen Saplings Thrive After 80-Year Absence

For the first time in 80 years, a new generation of young aspen trees is flourishing in Yellowstone National Park's northern range, thanks to the reintroduction of gray wolves in 1995. The wolves' presence controlled elk populations, reducing overgrazing that had previously prevented aspen saplings from establishing themselves. A new study published in Forest Ecology and Management highlights the significant ecological benefits of restoring top predators. The recovery of aspen is boosting biodiversity, benefiting various species including berry-producing shrubs, insects, birds, and beavers.
