It’s been 200 hundred years since bison roamed the prairies of Kane County, but a new plan to reintroduce them into a local forest preserve may turn back the clock.
Kane County Forest Preserve commissioners approved a plan this week to bring a handful of bison to the Burlington Prairie Forest Preserve. The plan centers on one of the main ecological goals of restoring tallgrass prairie to the county’s preserves. Before the surrounding area developed, fire and the grazing habits of wild animals, such as bison, provided natural management of the grasslands. Preserve officials reintroduced controlled burns to the preserves many years ago.
Executive director Ben Haberthur told commissioners now is the time to reintroduce bison to restore the grazing aspect of grassland management. Up to 90% of the diet for bison is grasses.
“The grasses evolved with grazing,” Haberthur said. “So it actually promotes the soil microbiome to grow more. Bison are native to Illinois, and they are definitely native to this county. They will bring a big component back to the ecosystem, namely fertilizer.”
District officials experimented with the benefits of animal grazing in the preserves with cattle in the Aurora West Forest Preserve. That experiment resulted in the flourishing of the restored grasslands in the preserve. Officials see bison as the next step in returning the grasslands to their most natural state and care.
The Burlington Prairie Forest Preserve is in the Pleasant Valley Conservation Alley north of Huntley and in the northwest portion of the county. The plan calls for two paddocks of 30 acres each with an additional 89 acres seeded for pasture. For the safety of the animals and the public, the areas containing the bison would be fenced, which accounts for the bulk of the initial cost of the project.

Editorial note: As we’ve suggested before, there is ample acreage at Horizon Farm for the Forest Preserves of Cook County to consider such an endeavor.
