Over the last decade, the conservation community has partnered with tribes, national parks and reserves to conserve wild bison, helping to bring back America’s national mammal. Because there are no longer millions of animals migrating across the plains, the bison is considered ‘ecologically extinct,’ but conservation herds of 1,000 or more bison are being established to create a metapopulation-from Canada to Mexico. The following story map presents data tracing all the way back to the 1920s on the transfer of bison between herds throughout the United States in this effort.
