Wildlife & Habitat

512x219 Bison Craig Tanner

Sullys Hill National Game Preserve is located on the south shore of Devils Lake in Benson County. The Preserve consists of 1,674 acres ranging from prairie to forested hills and is home to a wide assortment of wildlife including migratory birds, bison, elk, and prairie dogs.

  • Bison

    Plains bison were reduced from tens of millions to less than 1,000 by the mid-1880s. The bison is a symbol of historical significance in westward expansion and Native American culture. The Sullys Hill bison herd once played an important role in the conservation of plains bison. A small herd now managed for historical and educational value. The herd is managed at a population of less than 20 animals to keep the herd size in balance with the available habitat.

  • Migratory Birds

    It is estimated that up to 270 bird species may use Sullys Hill for both breeding and a stop over site.  The species most frequently detected in the woodland habitats of Sullys Hill NGP include the red-eyed vireo, yellow warbler (pitured on the left), common yellowthroat, eastern wood peewee, ovenbird, pileated woodpecker, hairy woodpecker and least flycatcher.

  • Elk

    150x118 Elk

    Rocky Mountain elk were eliminated from much of their former range due to habitat loss and over-hunting in the early 1900s. In 1917, fifteen elk were transported from Yellowstone National Park to Sullys Hill NGP. The elk is the second largest member of the deer family. The elk herd contains less than 18 animals to ensure sufficient forage. Listen for bull elk bugling to attract a harem of female cows in the autumn.

  • Prairie Dogs

    A colony of black-tailed prairie dogs was introduced to Sullys Hill NGP in 1975 to help educate the public about these unique rodents. Prairie dogs live within “towns" consisting of elaborate systems of underground tunnels and dens. Members of the town keep a watch out for predators, such as hawks, and let out a warning bark to other members when danger is present.
