An important part of a grizzly bear’s diet is high protein sedge grass. This grass grows in coastal meadows that are flooded with salt water every high tide. 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. Diets shift with the seasons, as summer approaches the berries start to replace the sedge grass and fall brings the salmon into the Glendale River.
