What tundra animals eat bearberry?

In the tundra ecosystem, animals such as caribou, Arctic foxes, and lemmings are known to consume bearberry (Arctostaphylos uva-ursi) as part of their diet. Bearberry is a common shrub found in the tundra regions and provides important nutrients for these animals, especially during the harsh winter months when food sources are limited. The high fiber content and vitamin C in bearberry make it a valuable food source for tundra animals, helping them survive in the cold and challenging environment.
