This 40-acre black soil native prairie is a remnant of what Plymouth County was like at the time of settlement. In the heart of the farming region of Plymouth County, this native tall grass prairie survived through the efforts of Erma O’Brien. Her heirs, in order to protect the prairie and make a lasting memorial, donated the prairie to the Plymouth County Conservation Board. The prairie is open to hiking, hunting and enjoyment of wildflowers. It is a great place for photographers and native prairie enthusiasts. O’Brien Prairie was donated to Plymouth County in 1988, when Wayne Simington inherited the land from the Erma O’Brien estate. The land originally came into the O’Brien family sometime between the Civil War and World War I. If you take a walk through to the prairie, it is likely that you could see between 50 and 100 different species of forbs (wildflowers) and grasses.
Public hunting, following DNR guidelines, is allowed.
