The American Bison (Bison bison), commonly called a buffalo, is the largest living land animal in the United States. It is also recognized as our national mammal. Once inhabiting much of North America, this species has suffered a dramatic reduction in its population. Over hunting and the introduction of bovine diseases from cattle has contributed to this decline. In response to this population crash, there have many conservation programs organized and directed at protecting herds of buffalo. Conservation herds in places like Yellowstone National Park suggest an overall population estimate of nearly 30,000 buffalo. However, commercial herds managed by private ranches have an estimated 500,000 individuals. It is important to note that these commercial herds are not wild free ranging populations. They are used primarily as a food source, offering more protein and less fat than cattle. These ongoing efforts have contributed to the International Union for Conservation of Nature (IUCN) to list the American Bison as Near Threatened.
