The Historical Society of Michigan's U.P. Centennial Farms grant opportunity is available for Upper Peninsula farming families who have owned and operated a working farm of 10 or more acres continuously for at least 100 years. This program aims to recognize the historical significance of these farms and their contribution to the culture and development of Michigan. Once certified through the Michigan Centennial Farm Program, owners will receive a certificate and a display marker for their farm. The green-and-yellow markers are sponsored by UPPCO in their Upper Peninsula service area.
