US Fish and Wildlife already are. They plan on stocking Grizzlies in Idaho, and other places. Rewilding Activists are planning to move "endangered species" into areas to gain control over them and move people, such as ranchers, farmers, logger, hunters, out.
Check this website to understand their motives more:

Most important is last paragraph on this page, which really describes their ultimate goals:
"The presence of top carnivores in an ecosystem not only holds ecological value but serves an economic and social purpose to humans. Rewilding, or more specifically trophic rewilding, is shedding light on the importance of predators and providing evidence of their benefits. T
he results will also help to advocate for the protection of existing trophic chains that are regulated by their top predator."
In other words: advocating for the protection of predator's food source, i.e., deer, elk, etc. A ban on hunting.
