The grassland biome is divided into the following habitats: Temperate grasslands: Temperate grasslands are dominated by grasses, lacking trees and large shrubs. There exist several other factors, including their size, diet, seasons, etc., all of which play a crucial role in their survival.

Mustang originates from the Spanish word "mesteno," which means stray or wild. It allows them to swing their heads from side-to-side to clear snowespecially for creating foraging patches. The height of vegetation on grasslands varies with the amount of rainfall. That would have made a world of difference for animals like pronghorn, which are not adapted for movement in deep snow. Bison also travel a lot, especially when the scent of a predator is forever on the wind. Bison was an important component of the flatlands ecosystem in its habitat. When blizzards blanket the plains with deep snow, bison use their heads as a plow of sorts to push aside the accumulation and reach the forage below. Elk Island has been a seed source of Canadian plains bison for many years, as they have no record of cattle or wood bison gene introgression and are free from diseases of conservation concern.
