The question of whether bison or buffalo are extinct is one that sparks immediate confusion, largely because the terms are used interchangeably in everyday language. In North America, the massive herds depicted in historical documentaries were bison, not true buffalo, and their survival is a testament to conservation efforts rather than a story of complete eradication. While the American plains were once dominated by an estimated 30 to 60 million bison, unregulated hunting in the 19th century reduced the population to fewer than 1,000 individuals by the late 1800s, creating the illusion of extinction.
Defining the Difference: Bison vs. Buffalo
To understand their extinction status, it is crucial to distinguish between the two animals. True buffalo—such as the African Cape buffalo and the Asian water buffalo—belong to the Bovidae family but exist in different genera and are native to Africa and Asia. The American icon, often called a buffalo, is scientifically named Bison bison, characterized by its massive shoulder hump, larger head, and a distinctive beard. This clarification is vital because when people ask if the buffalo are extinct, they are usually referring to the North American bison, whose story is one of dramatic decline and remarkable recovery.
The Brink of Extinction
During the westward expansion of the United States, the bison was hunted relentlessly for its meat, hide, and to subdue the Indigenous tribes who relied on them. By the 1880s, the commercial hunting and government policies aimed at destroying the Native American food supply brought the species to the absolute edge of biological extinction. The habitat that once spanned millions of square miles was fragmented, and the few remaining animals were scattered across private herds or desolate reserves, leading many naturalists of the era to believe the wild bison was finished.
Commercial Hunting and Population Collapse
Unregulated market hunting for hides and sport between 1870 and 1880.
Government policies encouraging the destruction of the herds to defeat Plains Indians.
Habitat loss due to the conversion of prairie land for agriculture.
The near-total reliance on a single commodity leaving the species vulnerable.
The rarity of the species creating a black market that hindered protection.
Modern Conservation and Current Status
Extinction was averted not by accident, but through the concerted efforts of a few dedicated individuals and organizations. Private citizens like Samuel Walking Coyote and Charles Goodnight began breeding small herds in the late 19th century, while the U.S. government established the Wichita Mountains Wildlife Refuge in 1907. Today, there are approximately 500,000 bison in North America, though the vast majority of these are in commercial herds. The key distinction is that while no longer endangered, the genetic purity and wild populations of the American bison remain a conservation focus.
Wild Populations and Genetic Purity
When discussing whether bison are extinct, the conversation often shifts to the health of the gene pool. Yellowstone National Park is home to one of the few remaining genetically pure wild bison herds. These animals are significant because they have not been crossbred with cattle, a practice that occurred in some commercial herds to create beefalo. The presence of disease, such as brucellosis, which can spread from bison to cattle, has led to controversial management practices like culling, which threatens the progress made in restoring this iconic species to the wild.
