While it would be cool to see Wood Bison in the game, the Plains Bison being on Yukon Valley is pretty realistic given the history of bison in Alaska
Basically what happened is back in the 1920s 7,000 disease carrying Plains Bison were introduced to Wood Buffalo National Park in Canada, which threatened the Wood Bison and until 1957 it was thought that the Wood Bison no longer existed. When a relatively pure herd of 200 Wood Bison were found in Northern Alberta about 23 of these bison were brought to Elk Island National Park and were later reintroduced to the Innoko River area of Western Alaska in 2015
By that point the introduced Plains Bison have existed in Alaska for almost 90 years and were only chosen because by the time bison reintroduction to Alaska was to take place the herd of 200 pure wood bison had yet to be discovered
I do agree that the Swamp Rabbits would be a good addition to Mississippi, but I don't see why the Eastern Cottontail has to be removed, especially since the two species live in different habitats on Mississippi Acres
I do agree that the Eurasian Wigeon does need to be replaced with some type of duck or goose that lives in Botswana and South Africa and the Egyptian Goose is one a lot of people know
