Why Fat Bears Matter

When it comes to bears, being fat equals survival. When a bear enters its den each winter, it will go into hibernation and not eat or drink until it emerges in spring.

During hibernation, a bear may lose up to one-third of its body weight, relying solely on its fat reserves.

Therefore, each bear’s survival depends on it eating a year’s worth of food within six months.
