Oak savannas—open grassland studded by tall, spreading oak trees—once covered 10 percent of Minnesota, mostly in the southeast quarter of the state. They are an attractive ecosystem for animals such as deer, turkeys, and red-headed woodpeckers. Before European immigration, indigenous people valued the savannas for the good hunting they provided, fostering and maintaining them through the regular use of fire. In 2017, only about 1 percent of the savannas that existed 200 years ago remains.

The Agricultural Extension Service of the United States (AES) began as an educational component of land-grant universities. In Minnesota as in other states, the federally funded and organized services of AES provide practical agricultural training to people outside of a university setting.

Wadena County contains three known fur trade sites. One is located on private property along the Leaf River where Joseph Réaume, an independent fur trader, set up a winter camp in the late eighteenth century. Between 2011 and 2012, the University of Minnesota conducted archaeological surveys and excavations at this location. They confirmed a late-eighteenth century occupation, validating its association with Réaume's 1792 wintering activities.

As Minnesota state legislators met on the evening of March 1, 1881, two days before the end of their twenty-second session, two pages alerted them to a fire in the building. Quick action by lawmakers and nearby residents saved important documents, furnishings, and historical collections. The fire took no lives but destroyed Minnesota's first capitol building.
