Types of Bison in New Jersey

Yes, American bison did roam the eastern United States thousands of years ago, including parts of what is now New Jersey. During the Pleistocene epoch and into early human settlement, bison herds occupied grassland regions across the eastern seaboard. By the 1600s, as European colonization expanded and forests were cleared for settlement, bison populations had already declined significantly in the Northeast. The combination of hunting and habitat loss pushed bison further west, eventually confining them to the Great Plains. Today, no wild bison populations exist east of the Mississippi River.

Three main forces eliminated bison from New Jersey and the entire eastern half of North America. First, habitat conversion: early colonists cleared vast forests for farming, fields, and settlements, destroying the open grasslands and prairies where bison thrived. Second, intensive hunting: bison were hunted for hides, meat, and sport, with no regulations or limits. By the 1800s, commercial hunters had reduced populations from roughly 30 million bison across North America to fewer than 1,000. Third, westward expansion drove bison further onto the Great Plains, where they remained until the same hunting pressure nearly finished them off completely by 1890.

Two living bison species exist: American bison and European bison. The American bison, which once ranged across New Jersey, is smaller and stockier than its cousin the African buffalo. American bison stand 5 to 6 feet tall at the shoulder and weigh 900 to 2,000 pounds, with males significantly larger than females. They have a distinctive shaggy brown coat, massive head, and pronounced hump over the shoulders. European bison, or wisent, are slightly taller and live in protected forests in Russia and Poland. Both species are now managed through careful breeding and conservation, found only in specific reserves and parks rather than roaming wild as they once did.

Wild bison now survive only in the western United States and Canada. The largest herds live in Yellowstone National Park, where roughly 4,000 to 5,000 bison roam across the park and surrounding lands. Other significant herds exist in Montana's National Bison Range, the Nature Conservancy's Tallgrass Prairie National Preserve in Kansas, and various Canadian parks including Wood Buffalo National Park. A few small herds are managed in Utah, Wyoming, and other western states. These protected reserves remain the only places where bison can live in something resembling their natural state, though even these populations are carefully monitored and managed to prevent disease and ensure genetic diversity.

A few New Jersey zoos and wildlife parks may keep captive bison for display and education, though they are not common. The Cohanzick Zoo in Bridgeton and the Space Farms Zoo and Museum in Sussex have housed various animals, but bison are not typically permanent residents at most New Jersey facilities. If you want to see bison up close without traveling west, your best option is to contact local wildlife centers and zoos directly. However, seeing bison in a zoo setting does not compare to observing them in their native grassland habitat, as their size, behavior, and social structure are difficult to fully appreciate in captivity.

New Jersey's forests and wetlands support excellent wildlife viewing opportunities, though not bison. Black bears are the state's largest wild mammal, weighing up to 600 pounds, and they are increasingly common across northern and central New Jersey, especially in autumn when they forage for food before winter. White-tailed deer are abundant throughout the state and can be spotted in forests, parks, and even suburban yards. Smaller mammals include bobcats, coyotes, raccoons, and foxes. For aquatic wildlife, beavers have made a strong comeback and are now common along streams and rivers statewide. Birdwatchers will find herons, eagles, and osprey near wetlands and waterways.

The elimination of bison had profound ecological consequences that reshaped entire ecosystems. Bison herds numbered in the tens of millions and shaped the Great Plains landscape through grazing patterns, nutrient cycling, and soil disturbance that kept prairies open and prevented forest encroachment. Their disappearance allowed woody plants and trees to invade grasslands, changing fire regimes and plant species composition. The loss also devastated Native American tribes whose cultures, economies, and diets depended on bison hunting. The deliberate destruction of bison herds was sometimes used as a deliberate strategy to force Native Americans onto reservations, adding a dark chapter to an already tragic extinction story.

Yes. Since the early 1900s, government agencies, nonprofits, and landowners have worked to restore bison to safe numbers and protected lands. The American Bison Society was founded in 1905 to prevent complete extinction, and its efforts helped reestablish herds in national parks and reserves. Today, roughly 30,000 to 60,000 bison live on public lands and private ranches across North America, a remarkable recovery. However, wild populations remain tiny compared to the historical 30 million. Some Indigenous nations have also begun restoring bison to tribal lands, returning the animals to territories their ancestors hunted. These efforts face ongoing challenges, including disease management, genetic diversity, and conflict with private landowners over grazing rights and movement.
