This research demonstrates that bison consistently rely on eudicots for protein with the functional group composition of their diet in some ways consistent across space and time, but also spatially and temporally variable.

Assessing the nutritional consequences of switching foraging behavior in wood bison

Evidence suggests that bison are selecting plants to maintain a target macronutrient composition, and posit that herbivore's can and will switch their dietary niche toaintain a target nutrient composition.

Reintroduced bison diet changes throughout the season in restored prairie

The analysis shows that bison primarily grazed on C4 grasses throughout the late spring and summer, but foraged more on wetland species and forbs in the late summer and fall, which could mean intended impacts of reintroduced bison such as increased plant diversity through preferential grazing on grasses could be dampened.

Diet and vegetation impacts of a reintroduced bison herd

Feeding preferences and nutritional niche of wild water buffalo (Bubalus arnee) in Koshi Tappu Wildlife Reserve, Nepal

The study suggests that buffalo are likely macronutrient specialists, yet may be generalists in the sense that they feed on a wide range of food items to achieve a nutrient balance similar to that available in forage items.

Evaluating trade-offs between forage, biting flies, and footing on habitat selection by wood bison (Bison bison athabascae)

Habitat selection is a behavioural process that ultimately affects animal fitness. Forage availability and predation risk are often studied in the context of habitat selection for large ungulates, ...

Forest closure and encroachment at the grassland interface: a century‐scale analysis using oblique repeat photography

We used repeat oblique photography to quantify and determine the drivers of vegetation change, particularly forest closure and encroachment, in the Rocky Mountains of southern Alberta, Canada, from

Latitudinal and seasonal plasticity in American bison Bison bison diets

This paper aims to provide a history of renewable resources in Alberta and some of the techniques used have been used in the United States, as well as some of those used in Canada.



Diet and habitat selection of wood bison in relation to seasonal changes in forage quantity and quality

Diet and habitat selection of wood bison were studied in the Mackenzie Bison Sanctuary, Northwest Territories, between February 1986 and April 1988 and showed pronounced seasonal changes in diet.

The relationship between feeding-time investment and forage patchiness is important in determining differences in diet choice between bison and cattle and it is suggested that specific scale-dependent programmatic conditions exist where either herbivore may be the most appropriate for natural area management.

Seasonal Shifts in Diet and Gut Microbiota of the American Bison (Bison bison)

It is suggested that North American bison can continuously adjust their diet with a high reliance on non-grasses throughout the year, and evidence is found for seasonal patterns in gut community composition that are likely driven by the observed dietary changes.

Foraging Ecology of Bison in Aspen Boreal Habitats

Forage intake rates and feeding times of Nortb America’s largest wild grazer, the bison, were related to forage biomass during summer and autumn in aspen boreal forest babitats.


It appears that bison select recently burned areas with relatively low graminoid biomass for grazing, presumably choosing these areas based on forage quality rather than quantity.

Spatial relations of American bison Bison bison and domestic cattle in a montane environment

Comparisons of the foraging distributions of sympatric bison and cattle in a 375–ha basin revealed that cattle were constrained by slope and distance from water, especially vertical distance, whereas bison responded mostly to forage availability.


Abstract Fire and bison (Bison bison) are thought to be historically responsible for shaping prairie vegetation in North America. Interactions between temporal–spatial distributions of bison and

Diets of bison and cattle on a seeded range in southern Utah Crested wheatgrass (Agropyron desertorum), alfalfa (Medicago sativa).

Diets of bison (Bison bison) mnd cattle (Bos taurus) were evaluated on a southern Utah range seeded to crested wheatgrass (Agropyron desertorum) and alfalfa (Medicago sativa), indicating a high potential for competition between bison and cattle.

Assessing Potential Habitat and Carrying Capacity for Reintroduction of Plains Bison (Bison bison bison) in Banff National Park

The successful reintroduction of bison into Banff would represent a significant global step towards conserving this iconic species, and the approach provides a useful template for evaluating potential habitat for other endangered species reintroductions into their former range.
