ISLE ROYALE - Researchers have found that wolves brought to Isle Royale in 2018 are likely to survive but face challenges from inbreeding and isolation. The island had only two inbred wolves in 2016, so officials introduced 19 new wolves between 2018 and 2019. A study published in Conservation Science and Practice shows the wolf population has over an 80% chance of lasting 20 years. However, inbreeding remains a significant concern. The wolf population has increased since the study ended, but the moose population, a key food source, has sharply declined, raising additional concerns for the ecosystem.
