As bison were notably vanishing by the 1860s, public outcry prompted some states to pass laws to protect bison, but enforcement was lacking and the massacre continued. The earliest efforts to rescue bison began in the late 1860s when a handful of private citizens independently began to capture and shelter bison, saving the species from extinction. These bison served as the foundation stock for most modern public and private bison herds today.
In the 1870s and 1880s, hundreds of bison occupied Yellowstone National Park. Despite the presence of the First U.S. Cavalry soldiers the park’s mission to, in part, protect wildlife, poaching of bison continued until Congress passed the Lacey Act in 1894. This legislation authorized the in Yellowstone to prosecute people that were killing or removing wildlife from the park.
In 1905, the American Bison Society (ABS) was formed to support bison recovery efforts, compelling Congress to establish several public bison herds at Wichita Mountains National Wildlife Refuge, the National Bison Range, Sully’s Hill National Game Preserve, Fort Niobrara National Wildlife Refuge, and Wind Cave National Park and President Theodore Roosevelt to establish the Grand Canyon Game Preserve. These efforts help save bison from extinction and the ABS disbanded in the early 1900s having accomplished their mission, however in 2005 the ABS was once again reestablished to help advance the ongoing restoration of bison to our lands and cultures.
