Agassiz National Wildlife Refuge in northwest Minnesota protects 61,500 contiguous acres of aspen parkland habitat, created in 1937 to support waterfowl production and maintenance. Wetlands dominate the refuge, alongside shrublands, forest, grassland, and limited cropland. It is notable for abundant wildlife, including wolves, moose, waterfowl, and 294 identified bird species, as well as 49 mammals, 12 amphibians, and 9 reptiles. In 1976, 4,000 acres were designated wilderness, preserving one of Minnesota’s westernmost black spruce–tamarack bog extensions and the bog lakes Kuriko and Whiskey. More than 20,000 visitors come each year for wildlife viewing.
