What animal does Mongolia lack most?

The rarest animal in Mongolia is the Gobi bear. Ursusarctosgobiensis is a subspecies of brown bear. Diet has always been: plant roots, berries, other vegetation, insects and mice. When it hibernates, food is very scarce. Much like the grizzly bear in North America, it can adapt to the arid environment in Gobi. Now Gobi bears are very rare and endangered. Mongolian name is Mazaalai, and it is the only bear that adapts to the desert climate.
