The National Park Service has formally started an Environmental Impact Statement process towards consideration of bringing more Grey Wolves into Isle Royale National Park, as only two aged wolves (father daughter) remain on the island now. At one point, there were as many as 50 wolves on Isle Royale, but inbreeding and resulting low fecundity took its toll.
The four options on the table:
- No action — let nature take its course.
- Bring in a few wolves during a one-time period, which could take a couple years.
- Bring in wolves multiple times over the next 20 years.
- Take no action now, and reconsider the top three options later on.
