Summer. From June through August, grizzly bears continue to consume succulent grasses and sedges, dandelion, clover, spring-beauty, horsetail, and ants. In addition, thistle, biscuit root, fireweed, fern-leaved lovage, and army cutworm moths are eaten.

Why do bears eat sedge grass?

Sedge grass stalks are spiky, wide and stiff but the sedge grass is up to 25% protein, and this is the reason why grizzly bears prefer eating it to other grasses. The spring a grizzly bears diets consist of approximately 70% of sedge grass to replenish their lack of proteins during hibernation.

What grasses do bears eat?

In spring, bears feed on willow catkins, grasses, dandelions, clover, and aspen leaves. Leaves and flowers are preferred when they are highest in protein content (shortly after leaf burst or flowering), before the cell walls build up lignin and cellulose and become more difficult to digest.
