Big Woods refers to a type of temperate hardwood forest ecoregion found in western Wisconsin and south-central Minnesota. "Big Woods" is a direct translation of the name given to the region by French explorers: Grand Bois. The theory of its origins maintains the ecosystem was formed 300 to 600 years ago in the protection "of topographic and water-based firebreaks during a period of cooler and moister climate".
