As the largest animal in the park weighing up to 2000 lbs., the Yellowstone herd is the last genetically intact population in the USA and faces many challenges, as do other species. One of these is the ever looming threat of brucellosis, that causes domestic cattle to abort their first pregnancy after exposure. According to NPS figures, 50% of the herd is infected and poses a potential threat to cattle in nearby ranching communities. Even though there has not been a documented case of transmission, the powerful cattle industry has firmly held that they risk the loss of their 'brucellosis-free' designation if this should occur. This has morphed into a program that slaughters Bison as they roam out of the park without any testing for the disease. Imagine if your doctor looked you over, discovered some skin pigmentation irregularities and scheduled cancer treatments without any verification. Does not seem like a very sensible approach to dealing with issue. Google 'yellowstone bison' and read and see for yourself. Education and knowledge can be a powerful insight!

The American Bison (Bison bison) is a bovine mammal, also commonly known as the American buffalo. "Buffalo" is somewhat of a misnomer for this animal, as it is only distantly related to either of the two "true buffaloes", the Asian buffalo (or "water bufallo") and the African buffalo. However, "bison" is a Greek word meaning ox-like animal, while "buffalo" originated with the French fur trappers who called these massive beasts boeufs, meaning ox or bullock. So both names, "bison" and "buffalo," have a similar meaning.

The bison once inhabited the Grasslands of the United States and Asia in massive herds, ranging from the Great Slave Lake in Canada's far north to Mexico in the south, and from eastern Oregon almost to the Atlantic Ocean, taking its subspecies into account. Its two subspecies are the Plains Bison (Bison bison bison), distinguished by its smaller size and more rounded hump, and the Wood Bison (Bison bison athabascae), distinguished by its larger size and taller square hump. Wood Bison are one of the largest species of cattle in the world, surpassed in size only by the massive Asian gaur and Wild Asian Water Buffalo, both of which are found mainly in India and Southeast Asia. It is also the largest extant land animal in North America.
