What happened to the Aspen Trees when the wolves returned to Yellowstone?

Answer 1

When the wolves returned to Yellowstone, they started preying on the elk population, which had been overgrazing the aspen trees. As a result, the elk population was reduced and the aspen trees were able to regenerate and grow more successfully. This led to an increase in biodiversity in the ecosystem and a healthier forest overall. The presence of wolves helped balance the ecosystem and allowed the aspen trees to thrive once again.
