Paektu Mountain
Most Korean mammal species are found only in a small part of Korea. The large southeastern island of Jeju, and the rugged northeastern Paektu Mountain region, are particularly known for their distinctive mammal species. Several species, including the Dsinezumi shrew, are found only on Jeju, while many other species, such as the wild boar, are absent or extirpated from there. Some mammals, such as the Manchurian wapiti, are considered natural monuments of North Korea, while others, such as the spotted seal, are considered natural monuments of South Korea.
