context_page_description: The Nachusa Grasslands is a 3,800 acres tallgrass prairie conservancy located near Franklin Grove in Lee County and Ogle County, Illinois. It is managed by The Nature Conservancy staff and volunteers.
context_section_description: The Nachusa Grasslands planning process called for running up to 100 American bison (Bison bison, also commonly known as "buffalo") on approximately 1,500 acres (610 ha) of the preserve. Thirty bison were released on the Nachusa Grasslands in October 2014. The bison were added to the approximately 700 species logged at the prairie. In April 2015, free-range bison calves were born, adding to hope that the Nachusa herd could be managed so as to be self-sustaining. As of July 2015, 14 calves have been born at Nachusa.
