Yellowstone National Park was founded in 1872 and housed over 130 gray wolves. Up until the 1940s or 50s, the wolves were exterminated because nobody understood the necessity of predator vs. prey, and saw wolves as destroyers of elk and deer. By the mid-1900s there wasn’t a wolf population inside the majority of the lower 48 states, much less in Yellowstone. Throughout the following decades, environmental issues reached the national level and gained more attention. Many people started suggesting that wolves had to be brought back for the good of the ecosystems.
Then in January 1995, 14 wild wolves were captured in Alberta, Canada, and brought to Yellowstone. The wolves were from 3 packs and one lone male wolf. They were placed into 3 different acclimation pens. The pens were a fenced-in acre that let the wolves get used to Yellowstone without being in danger. The Yellowstone staff would bring elk, deer, and bison carcasses 2 times a week.
The Rose Creek pack consisted of wolf 9 (mother) and wolf 7 (her pup). The rest of their original pack had been killed, so wolf 10 (the lone wolf) was introduced to them. The Crystal Creek pack was made up of wolves 5 and 4 (alpha female and male respectively) and their 4 pups (2,3,6,8). The last 5 wolves were called the Soda Butte pack.
The wolves were kept in their pens for 10 weeks. After that, the fences were cut because the wolves were too scared to use the gates the people used. Over the next 10 days, all the wolves were out and roaming freely. The packs all started taking control of territories.
The story of the Rose Creek pack is one of the first instances of pups being born in Yellowstone again. First, the yearling wolf 7 left her mother. Then wolf 9 and 10 left the park and when they were tracked down, wolf 9 was nearing the end of her pregnancy. Sadly, wolf 10 was illegally killed by Chad McKittrick. The same day 10 was shot, 9 gave birth to 8 pups(including 16,17,18,19, and 21). This pack was brought back to 9’s original pen for 6 months for safety. There are still descendants of 9 and 10 in the park today.
While the Rose Creek pack was in their pen, yearling wolf 8 from the Crystal Creek pack visited them and helped take care of the pups. This led 9 to accept him and become his mate. 8 and 9 went on to have several litters together and had one of the biggest packs in Yellowstone. 9’s son, 21, was also the biggest wolf in the history of Yellowstone.
In 1996, more wolves were brought in from Canada, growing the gene pool. In 1997, 10 more wolves were brought in from Montana. As of January of this year, there are at least 108 wolves inside the park in 10 different packs. Wolves have helped balance prey populations, bring back plants, etc. This was one of the most successful reintroduction projects in history. I hope that this kind of success can be achieved in all reintroduction/restoration projects from now on.

Questions:
- Did you know about this?
- Have you ever been to Yellowstone? If so, did you see a wolf?
- Is there another animal that should be restored/reintroduced in its natural habitat?

I actually learned about the reintroduction of wolves into Yellowstone when we went there. In many places or trails, there are informational topics that are explained, and one place even had a documentary playing following a pack of wolves introduced into Yellowstone. Even though I have been to Yellowstone, I haven't seen wolves, but I did see many bears, mountain goats, and bison.
When I went to Yellowstone I saw some of those signs too. I didn't see any mountain goats though.
I did not know about Yellowstone putting wolves back into their natural habitat. Yes I have been to Yellowstone; however, I have never seen a wolf before at the park. I am unsure of other animals that should be reintroduced in their natural habitat.
I've been to Yellowstone, but didn't see a wolf either.

I did not know about wolves being reintroduced into Yellowstone National Parks. I have never been to Yellowstone, but I would like to visit sometime when I get older. I think that we should try to reintroduce a greater population of elephants into Africa.
I don't know how they would go about it, but I agree that the African elephant population needs to grow.
I have never been to Yellowstone before but it definently sounds like a really cool place to visit. I think what Yellowstone is doing for the wolves bringing them to their natural habitat is awesome and im sure they will be more happy protected.
I agree that Yellowstone is amazing for doing this.
I did not know about this. I have also never been to Yellowstone but it's been a place that i've always wanted to visit. I think it's so interesting to see the way certain animals can restore nature without us even realising.
