An enduring symbol of freedom and the West, bison once roamed the U.S. grasslands.
While the landscape of the USA has changed in modern times, the love for this majestic mammal has remained a constant. The National Bison Legacy Act was signed into law by U.S. President Barack Obama in May 2016, making bison the USA's national mammal. Thanks to the work of conservationists, the National Park Service and private land owners, bison herds are growing nationwide, increasing from just 1,000 in 1890 to more than 500,000 today.
What Are Bison?
Unique to North America, bison are the continent's largest mammal, and can grow to 2 meters tall and weigh up to 907 kilograms. They're grass-eating herbivores and are covered in shaggy black-brown fur, which protects them from the cold, snowy winters. Bison mate in summer before giving birth to a single red-colored calf in spring.

Bison or Buffalo?
Bison is the scientific term for this mammal, but they're also called buffalo. Which is correct? Technically, the word "buffalo" just refers to African and Asian buffalo, whereas the North American bison is related only to the European bison. But the name buffalo has been used for so long that you'll see it as a common alternative.

To people in the U.S., bison have long been an emblem representing the country's frontier roots, gracing the U.S. Department of the Interior seal, the National Park Service Arrowhead logo, and at one time, the back of the United States' five-cent coin, the nickel. The unofficial anthem of the West, "Home On the Range," begins with the line, "Oh, give me a home where the buffalo roam." Plus, many U.S. cities and sports teams also bear the buffalo name.

Where You Can See Bison
Bison are now found in nearly every U.S. state, but the best place to see wild herds is Yellowstone National Park. Most bison have been crossbred with cattle over time, but Yellowstone's remain purebred.
Yellowstone is the only place bison have lived continuously since prehistoric times, and their herd numbers nearly 5,000—making it the largest group of free-range bison.
You'll also find bison at protected locations throughout the United States: Antelope Island State Park in the Great Salt Lake near Salt Lake City, Utah; National Bison Range in Moiese, Montana; Catalina Island near Los Angeles, California; Land Between the Lakes Elk and Bison Prairie in Golden Pond, Kentucky; Theodore Roosevelt National Park in Medora, North Dakota; and Golden Gate Park in San Francisco, California.

Look But Don't Touch
While these massive mammals appear calm and slow to visitors, they're among the most dangerous wildlife to encounter. The National Park Service says bison can sprint three times faster than humans, and they're known to charge, throw or gore humans when threatened. National park visitors are required to stay 23 meters away from bison, as their behavior can be unpredictable; you should never approach or touch one.

Bison and Native Americans
Long before the first settlers arrived in the United States, Native Americans hunted bison. Fundamental to tribal culture and survival, they used every part of the bison for food, clothing, shelter and tools.
Today, the National Wildlife Federation (NWF) is leading the effort to return wild bison to tribal lands. Through partnerships with tribal leaders, the NWF is working to restore the cultural connection with bison for Native American tribes and creating space for free-roaming herds to graze in their historic habitats.
No matter where you roam in the United States, be sure to see this living fixture of the Wild West along the way.
