In Yellоwstоne Nаtiоnаl Pаrk, the reintroduction of wolves had a significant impact on the ecosystem. The wolves' predation on elk led to a decrease in the elk population. This, in turn, allowed for the recovery of aspen and willow trees, which are a primary food source for beavers. The subsequent increase in the beaver population and the building of new dams is a result of the wolves' presence.
