The American bison is a species of bison that were earlier found in North America with vast populations of millions. There are two subspecies known to us namely the plains bison (Bison bison bison) and the wood bison (Bison bison athabascae).
The plains bison (bison bison bison) had an overflowing population on the Great Plains, but due to excessive commercial hunting and slaughtering their population declined and these species of bison came near the possibility of getting extinct.
With conservation efforts from private landowners, state and federal agencies their population is being monitored in few places as Western Dakota, Wyoming, Montana, Colorado, and Texas.

Plains Bison Interesting Facts
What type of animal is a plains bison?
Plains bison (Bison bison bison) belongs to the family of Bovidae order Artiodactyla. These animals live in herds of 30 individuals and graze on grasses throughout the year. Male bison will establish a supremacy ranking that keeps changing during the breeding season. Plains bison are well adapted to their native habitat of meadows and grasslands regions.
What class of animal does a plains bison belong to?
Plains bison belong to the Mammalia class of animals. The presence of mammary glands to feed their young ones, with three ear bones, fur coat or hair, and the neocortex (region of the brain) are what qualifies plains bison as a mammal. In their range, these herbivorous animals control the plant communities by grazing.
How many plains bison are there in the world?
The total population of plains bison around the world is less than 20,000 individuals with all of them spread across the regions of North America. With the largest herd of 4,500 available in Yellowstone National Park.
Where do plains bison live?
Plains bison were earlier found in the vast areas of Northern Mexico to Alaska, but with the rapid decline in their population due to overhunting and commercial slaughtering, these animals are now found in the National Parks like the Yellowstone National Park in Wyoming, Northwest Canada, and Wolf Buffalo Park.
What is a plains bison's habitat?
Plains bison were earlier found throughout the Savannas and grasslands of North America. These animals prefer a semi-desert habitat with suitable grazing land. Due to their limited populations, these animals occupy all the elevation of the protected areas.
Bison appear to have been less abundant east of the Appalachian Mountains and rare within the forested mountains. An Englishman first reported bison near the Potomac River in 1612.
Who do plains bison live with?
Plains bison are social animals and they are found together in groups of 30 individuals according to their habitat, age, season, and sex. The female (cow) group comprises males under the age of three years old and a few older males and males enter these groups during the breeding season.
Males (bulls) that are higher on the hierarchy, breed more often compared to the lower-ranked bulls.

Plains bison have a lifespan of up to 10-20 years in the wild.
How do they reproduce?
Female plains bison reach their sexual maturity at the age of two years old, giving birth to a calf in a two to three years gap with a gestation period of nine months.
Whereas the males sexually mature at the age of 3 years but usually breed only if they reach the age of six years old when they grow stronger to compete with other males for mating rights.
The breeding season of plains bison starts from the month of June extending till September.
Females give birth to their calves away from the herd in an area that has a good cover to protect them from predators, while the males do not participate in raising the calves. A newborn calf weighs around 33-55.1 lb (15-25 kg), with red color fur which turns brown three months after its birth.
Females will nurse and take care of their calves for almost seven to eight months.
What is their conservation status?
As per the IUCN Red List, the plains bison are listed as Near Threatened species due to the decline of their vast population of millions because of overhunting and commercial slaughtering.
These endangered animals had an overflowing population on the Great Plains and are found in small herds in the conservation reserves made by private landowners, state and federal agencies.
These bison herds have survived the ice age but now they are on the verge of getting extinct.
Defenders of wildlife support the conservation of bison on both tribal and public lands which have helped in increasing the bison numbers in the wild and national parks like the Wind Cave National Park and Yellowstone National Park.
