Neal Smith National Wildlife Refuge

The Neal Smith National Wildlife Refuge is a federal national wildlife refuge located in Jasper County, Iowa, United States. The refuge, formerly known as Walnut Creek, is named after Congressman Neal Edward Smith, who championed its creation. It seeks to restore the tallgrass prairie and oak savanna ecosystems that once covered most of Iowa. It has a herd of approximately 62 American bison and 19 elk. An initial group of six bison were released in 1996. The bison herd roams an approximately 800-acre enclosure (320 ha).
