According to the Ministry of Environment and the Korea National Park Service, four adult female Asiatic black bears have given birth to a total of six cubs this year. They confirmed the existence of the cubs through cameras installed in and around the bears' hibernation area. Asiatic black bears hibernate from around the end of December to March the following year, and usually give birth to one or two cubs in January or February in their hibernation den. The cubs grow quickly, weighing around three to four kilograms when they come out of the den.
