Big Stone National Wildlife Refuge was originally purchased by the U.S. Army Corps of Engineers and was transferred to the U.S. Fish and Wildlife Service on May 21, 1975. The refuge currently includes 11,586 acres in Big Stone and Lac qui Parle Counties, in Minnesota.

It's Baby Season!

Our breeding birds have settled in and are raising their young. Fawns can be seen jumping behind their mothers. There's a lot of new life on the prairie. You can help by leaving young animals where you find them (mom is likely nearby or just needed a break!) and keeping pets on a leash. Waiting to hay fields until after July 15 assures that most grassland birds have successfully raised their first round of chicks.
