What percentage of the Toronto Zoo wood bison diet constitutes sedges and grasses?
Answer
85 percent
The wood bison is fundamentally an obligate grazer, meaning its primary energy source must be graminoids. Observations conducted on herds at the Toronto Zoo specifically quantified this dietary reliance, establishing that approximately 85 percent of their total annual intake is derived from grasses and sedges. This high concentration of graminoids provides the necessary bulk energy required for such a massive mammal to maintain its bulk throughout the year, distinguishing their core nutritional strategy from animals that rely heavily on browse or mixed forage.
