Habitat
Bison historically occurred throughout the grasslands and open savannas of North America. However, they were also found from boreal habitats to semi-desert habitats if grazing was suitable. Bison are now more limited in distribution and, therefore, the habitats they occupy. They are currently found in disjunct populations in protected areas throughout western North America. They occupy a large elevational range, being found at all elevations in the protected areas they occupy (Meagher, 1986).
Food Habits
Bison are year round grazers. They feed primarly on grasses, but when food is scarce, they will eat vegetation such as sagebrush. On average, bison ingest 1.6% of their body mass per day of dry vegetation. Bison require water every day as well (Meagher, 1986).
