Zoology: Nachusa Bison

In 2014 the Illinois Chapter of the Nature Conservancy reintroduced a herd of wild bison onto the 3,500-acre Nachusa Grasslands prairie restoration site in Franklin Grove, Ill.  

The return of the bison was the result of more than 30 years of work by volunteers replacing an area once used as farmland with native plants and grasses. The group had been managing the land through a series of controlled burns. However, conservationists are hoping the bison, with their selective grazing habits, will serve to better manage the land.  

After raising the funds and readying the land, a team from Nachusa traveled to the Broken Kettle Grasslands Preserve in Westfield, Iowa and brought back with them Nachusa's herd.

  • Project director Bill Kleiman and Becky Hartman drove to take part in a prescribed burn, their only way of controlling vegetation before bison, at the Nachusa Grasslands prairie restoration site in Franklin Grove, Ill.
  • Volunteers Kirk Hallowell, left, and Dave Lawson used drip torches to ignite a prescribed burn. During each burn, non-native plants are removed, allowing prairie plants more nutrients and room to grow. A prescribed burn is a crucial component in prairie restoration.
  • Crews worked to build the bison corrals in preperation for introducing the first herd of animals at the Nachusa Grasslands.
  • Scott Moats, director of stewardship for the Iowa chapter of The Nature Conservancy, and Emily Hohman, the western Iowa land steward, used four wheelers to drive their herd of bison into a trap pasture the evening before the annual roundup at the Broken Kettle Grasslands Preserve in Westfield, Iowa.
  • David Crites, a longtime volunteer at Nachusa Grasslands, pushed a group of bison into the corrals during the annual roundup in Iowa.
  • Veterinarian Dr. Travis Hawkins drew blood from a bison as it sat in a squeeze chute. Of the animals processed during the roundup, 20 would return to Illinois to form a new herd at the Nachusa Grasslands.
  • Julie Brockman, a graduate student at Southern Illinois University Carbondale, hauled a hose from a pumper truck to deliver drinking water for the troughs in the bison corrals.
  • Emily Hohman, the western Iowa land steward for The Nature Conservancy, right, tried to move a group of bison through a sweep tub onto a truck bound for the Nachusa Grasslands in Illinois.
  • Cody Considine, the restoration ecologist at Nachusa Grasslands, celebrated after the last group of bison were loaded onto the truck.
  • Bison handlers worked to coax a group of 18 bison off a semi truck after it arrived at the Nachusa Grasslands prairie under the cover of darkness in Franklin Grove, Ill. The animals were unwilling to leave the truck after making the trip from the Broken Kettle Grasslands.
  • After many failed attempts at unloading the bison the Nachusa team decided to leave the animals on the truck with the door open overnight allowing them to eventually come out on their own.
  • Volunteer Ruth Bowers-Sword worked to clear a stretch of old fence in what would eventually be the south bison unit at the Nachusa Grasslands. The new pasture would more than double the bison's overall area.
  • A lone bison stood among the native grasses as he led the herd of about thirty animals into the corrals in the late evening at the Nachusa Grasslands.
  • One of two large male bison grazed at the Nachusa Grasslands prairie restoration site as the season's first snowfall blaketed the area in white.
  • A bison cow nursed her calf as they stood with the herd in the tall grass at the Nachusa Grasslands. More than 10 bison calves were born in the herd's first year in Illinois.
  • A bison peered out from the corrals during the first Nachusa bison roundup, roughly one year after the animals first came to Illinois.
