Which animals disappeared from much of settled Saskatchewan by the early 1900s?

By the early 20th century, several animal species had been extirpated from the more settled regions of Saskatchewan. These animals included the wolf, bison, grizzly bear, and the black-footed ferret.1

While some of these species have since made a comeback through conservation efforts, their disappearance at the time was largely a result of the rapid expansion of settlement and hunting pressures that transformed the landscape.12
