BASIC FACTS ABOUT BISON

Millions of bison once thundered across North America. The giant animals, characterized by, shaggy brown coat their long, have poor eyesight but acute hearing and an excellent sense of smell.



Historically, American bison play an essential role in shaping the ecology of the Great Plains. They graze heavily on native grasses and disturbing the soil with their nails, allows many species to grow. Prairie dogs prefer areas of bison graze where the grass is short so they can keep a lookout for hungry predators, wolves and had to rely on bison herds are a major food source. Today, wild bison are making a small comeback in some places scattered, but they need more room to roam.

Diet
Bison eat mostly grass and sedges.
Population
Do you know?

Carved trails of animals such as bison and deer in their migration season formed some of the earliest tracking paths into the wilderness of America, and were followed by Native Americans, the explorers and pioneers.

An estimated 20 to 30 million bison once dominated the landscape from the Appalachians to the Rockies in North America, from the Gulf of Alaska. habitat loss and unregulated shooting reduce the population of just 1,091 in 1889. Today, about 500,000 bison live across North America. However, most of these are not pure wild bison, but have been crossbred with cattle in the past, and sell domesticated after being raised as livestock for many generations on the farm. Less than 30,000 wild bison in the herd conservation and less than 5000 are no fences and disease.

Scope & Habitat
Although bison once roamed throughout North America, today they are "ecological extinction" as a wild species throughout most of their historic range, except for a few national parks regional and other small wildlife. Yellowstone National Park has the largest population of wild bison Plain (4000), and Wood Buffalo National Park has the largest population of natural wood bison (about 10,000). With help from the defenders, two small herd of pure, wild Yellowstone bison were recently reintroduced to Fort Peck and Fort Belknap to Indian reservations.

Behavior
Do you know?

thick fur of a bison provides excellent protection against harsh elements of the American plains. Their winter coat is too thick and well insulated that snow can cover the back without melting.

Known for great distances roaming, bison migrate continuously as they eat. The females, or cows, lead family groups. Bulls remain solitary or in small groups for most of the year, but that group during mating season.

Bison are adapted to the harsh weather conditions of the Great Plains, from summer heat to winter cold and snowstorms. In the winter, bison can dig through deep snow with their heads to reach the vegetation below.

Bison often rub, roll and wallow. Immersed create a saucer-like depression in the ground called immersed. This has been a common feature of the plains; is often the Dust Bowl wallows without any vegetation.

Born
Bulls and cows are not integrated until the breeding season. dominant bulls "tend" the cow after cow until the cow around selected for mating. During this time, the volume of cattle beef vision so she could not see the other competing bulls, and bellows in men striving for the attention of cattle.
