Wolf pups are roaming Isle Royale National Park for the first time in at least five years.
The park has been working to rebuild the wolf population after researchers found only two wolves in 2015.
“There was a lot of concern at that point that the wolves were not able to reproduce and that the top predator in the ecosystem would be gone from the land scape. That would be bad for the entire ecosystem,” said Isle Royale National Park Public Information Officer Liz Valencia.
In 2018 and 2019, the park brought in 19 wolves to island.
