The Ussuri black bear (Ursus thibetanus ussuricus), also known as the Manchurian black bear, is a large subspecies of the Asian black bear native to the Far East, including the Korean Peninsula.[1][2][3]

Sympatric predators include the Ussuri brown bear and Siberian tiger.[2][3]

Ussuri black bear
Accepted scientific name: Ursus thibetanus ussuricus (Pierre Marie Heude, 1901).
Description: Also known as the Manchurian black bear (in South Korea). The largest of the Asiatic black bear subspecies. They have the characteristic cream or white “moon” collar of Asiatic black bears but have larger ears compared to the other subspecies. Males typically weigh up to 200 kilograms, females up to about 140 kilograms.
Range: Named for the Ussuri River in the far east of Russia. Central and eastern Asia; specifically Southern Siberia, northeastern China and the Korean peninsula. Mountains of North and South Korea. Divided from the central Chinese population of U. thibetanus for several thousand years by human presence, accompanying land-use and poaching for gall bladders.
Habitat: Found in small numbers in the mountains of North and South Korea (at one time less than thirty bears remained in South Korea but a reintroduction programme is underway). In northeast China mainly found in conifer forests and in Siberia in broad-leaved forests.
Status: In common with all Asiatic black bears, Ussuri black bears are classified as vulnerable by the IUCN. South Korea designated them as a Natural Monument Species in 1982 and as an Endangered Species in 2005. The Asian black bear is listed as a protected animal in China’s National Protection Wildlife Law.
Life span: Likely to be 20 to 25 years in the wild. Up to 30 years in captivity.
Food: The bears are omnivorous although predominately herbivorous feeding on grasses, herbs, fruits, nuts including acorns, pine nuts, larvae, invertebrates, termites, small mammals, eggs, bees and honey. They will also eat carrion when available and take grain from areas of cultivation.
Behaviour: Ussuri black bears generally spend the winter in dens. They are mainly nocturnal when in the vicinity of humans but are more naturally diurnal spending about half their time in trees, often on platforms made from branches and vegetation. They have the reputation of being extremely aggressive towards humans Except during mating and for females with cubs they are solitary. Mating occurs in June and July with litters of from one to three, exceptionally four, cubs being born in January and February in the winter den. Cubs remain with their mother for around eighteen months during which time she will not become pregnant again.
Threats: Habitat loss, most often from forestry, and the resultant human conflicts are the main threats to these bears. This also makes them more vulnerable to poaching for body parts to be used in medicine and to capture for use in bear bile farms.

Body mass and physical changes of reintroduced Asiatic black bears
Abstract and Figures
The information on animal weight is often an essential component of wildlife management and research. However, it may be difficult to obtain direct scale weights from the free-ranging large animals when equipment needed to weigh the animals are inadequate or unavailable. In these cases, body weight can be estimated by morphometric equation. We investigated body mass and size (16 body parts) of reintroduced Asiatic black bears (Ursus thibetanus; ABB) and their offsprings (28 males and 24 females, age 7 months − 12 years) between 2005 and 2013. Mean body weight of adult females and males in September − December were 132.2 ± 11.8 and 166.6 ± 7.2 kg, respectively, which was higher than those in April − August (103.8 ± 5.6 and 141.7 ± 6.3 kg, respectively). We developed three predictive equations for body mass by pad width and season that can utilize the footprint size before capturing. In addition, we also developed eleven multiple regression models to predict body mass through body part measurements after capturing, and selected two best models including neck girth, chest girth, body length, season, and sex. This study is the first to develop predictive equations for body mass by simple measurements of body parts in ABB. This data will not only help to understand the relationship between the weight and body size of reintroduced bears, but by estimating the weight without a scale, it will help to make the task easier and faster and to determine the appropriate anesthetic dose in the field.

From reply #5:
So researching and researching i have finally found the average weight of the Ussuri black bear of South Korea:
Males-September-December-166.6 kg (367 lbs) Males-April-August-141.7 kg (312 lbs)
Females-September-December-132.2 kg (291 lbs) Females-April-August-103.8 kg (229 lbs)

Can you guess an average weight of a black bear in year around?

Can you guess an average weight of a black bear in year around? There is no average for year round. September to December is when the bear is preparing for hibernation and April to August is after hibernation.
