Dogs are never allowed on the Konza Prairie. It is a private research station, including on race day.
The Konza Prairie Biological Station is an 8,600 acre site just south of Manhattan, devoted to research, education, and conservation in the tallgrass prairie. Over 96% of the original tallgrass prairie has been converted, and large intact tracts are rare.
The trails are the reason to toe the line. Proceeds go to the Konza Environmental Education Program, which brings K–12 students onto the prairie.
