Grasslands National Park is home to numerous prairie species, including the only black-tailed prairie dog colonies in Canada. The park has successfully reintroduced plains bison, which now roam freely in the West Block. Other notable species include pronghorn antelope, swift fox, ferruginous hawks, and greater sage-grouse. The park provides critical habitat for endangered species such as the black-footed ferret and burrowing owl. Visitors might also encounter rattlesnakes, short-horned lizards, and various grassland bird species.
The park protects one of North America's largest remaining intact grasslands, featuring mixed-grass prairie vegetation. Dominant species include blue grama grass, needle-and-thread grass, and western wheatgrass. The park harbors over 70 species of grass and more than 50 species of wildflowers, including the endangered western spiderwort. Sage brush, cacti, and other drought-resistant plants thrive in this arid environment. Spring brings colorful displays of wildflowers such as prairie crocus, yellow umbrellaweed, and scarlet mallow.
The park showcases dramatic badlands formations and rolling prairies shaped by millions of years of erosion. The Frenchman River Valley, carved during the last ice age, features exposed layers of sedimentary rock dating back 70 million years. The East Block contains the Killdeer Badlands, where erosion has revealed fossil-rich deposits from the Late Cretaceous period. Rock formations include distinctive striped hills, hoodoos, and ancient river channels. The park's geological features provide important evidence of prehistoric life, including numerous dinosaur fossils.
The area now known as Grasslands National Park has been home to Indigenous peoples for thousands of years, particularly the Blackfoot, Assiniboine, and Gros Ventre nations. European settlement began in the late 1800s, bringing ranchers and homesteaders who transformed the landscape. The park was established in 1981 to preserve one of North America's most endangered ecosystems - the mixed-grass prairie. The park's creation involved voluntary land purchases from local ranchers over several decades, with the West Block opening to the public in 1989 and the East Block in 1997.
Key attractions include the Ecotour Scenic Drive in the West Block, offering views of prairie dog colonies and bison herds. The East Block's 70 Mile Butte provides panoramic views of the prairies and badlands. The park offers some of the darkest night skies in Canada, making it perfect for stargazing. The Two Trees Trail and Broken Hills Trail offer hiking opportunities through diverse prairie landscapes. The park also features several archaeological sites, including ancient teepee rings and buffalo jump sites, providing glimpses into Indigenous peoples' historical use of the land.
Grasslands National Park experiences a semi-arid continental climate with extreme temperature variations. Summers are hot and dry with temperatures often exceeding 30°C (86°F), while winters are cold with temperatures dropping below -20°C (-4°F). The park receives relatively low precipitation, averaging 350mm annually, with most rainfall occurring in late spring and early summer. Strong winds are common throughout the year, and the region experiences frequent dramatic weather changes. Visitors should be prepared for sudden temperature shifts and intense summer thunderstorms.
