Grasslands National Park, located in the southwest corner of Saskatchewan, protects some of the largest remnant blocks of (nearly) undisturbed mixed-grass prairie in North America. However, the prairie is not as it was prior to European arrival: the disappearance of bison with the associated loss of grazing pressure and soil disturbance means the dynamics and composition of the plant community have changed. Parks Canada is reintroducing bison into the park this upcoming winter in a limited area, with the intent of restoring the land to a more natural state (and likely also increasing visitors - we saw only about a dozen people in the park proper all day long).

There are no apparent plans, however, to reintroduce the plains population of the grizzly bear (more).
