Many people wanted to protect the grasslands in the area. They also wanted to protect the plants and animals that lived in the area. In the 1950s and 1960s, many people wanted a large area of grasslands protected. A study in 1965 showed that this area of Saskatchewan would be the best place to start a park. Both the governments of Alberta and Saskatchewan created a group to listen to the public's opinion in 1975. The group said that the public wanted the park to be created.
