The American bison is the biggest
mammal
in
North America
.
[1]
There used to be as many as 30 million bison in the United States, but because of hunting, by 1890, only 1000 bison were left.

Through
conservation
efforts, there are now more American bison than there used to be, but still far fewer than there were before the 1800s.
European bison (
wisent
) tend to live in lightly wooded to fully wooded areas and areas with increased
shrubs
and
bushes
, though they can also live on
grasslands
and plains.
They live to be about 20 years old and are born without their "hump" or horns, which both males and females have. After shedding their lightly colored hair, and with their horns, they are grown at 2 to 3 years of age, but males keep growing slowly until seven years. Adult bulls are very dominant in mating season. Adult bison usually have one or two baby bison.
