The American bison or simply bison, also commonly known as the American buffalo or simply buffalo, is a North American species of bison that once roamed the grasslands of North America in massive herds. Their historical range, by 9000 BC, is described as the great bison belt, a tract of rich grassland that ran from Alaska to the Gulf of Mexico, east to the Atlantic Seaboard (nearly to the Atlantic tidewater in some areas) as far north as New York and south to Georgia and per some sources down to Florida, with sightings in North Carolina near Buffalo Ford on the Catawba River as late as 1750. They became nearly extinct by a combination of commercial hunting and slaughter in the 19th century. With a population in excess of 60 million in the late 18th century, the species was down to 541 animals by 1889. Recovery efforts expanded in the mid-20th century, with a resurgence to roughly 500,000 animals today, largely restricted to a few national parks and reserves.
