( 7 ) - Ussuri black bear (Ursus thibetanus ussuricus), native to the Korean peninsula, southern Siberia, and northeastern China Great to know. How much do the Ussuri black bear native to the Korean peninsula, southern Siberia, and northeastern China get in weight?

440 pounds ( 200 kg ) is the normal max; but there have been some huge Asiatic black bears recorded. Big Bonns once had post with some reliable data - and pictures.

www.bearconservation.org.uk/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 ( 441 pounds ), 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.

The Ussuri black bear is subordinate to an Ussuri brown bear just like an American black bear is subordinate to a grizzly bear in its realm. Ussuri black bears seem to be more aggressive than their American counterparts.

What i would like to find is any account of an Ussuri black bear at least besting an Amur tiger. We dont have any account like this.

For the same reason we have nothing on camera of a Russian grizzly / Amur tiger conflict at a kill site. Its much easier to film lions in Africa or even tigers in India.  |

shaggygod.proboards.com/ The Asiatic black bear inhabiting the south of the Russian Far East (RFE) belongs to Ussury subspecies (Ursus thibetanus G. Cuvier 1823). This is the northeastern edge of the species' range. These animals are characterized by black color, a prominent crescent-shaped marking on the chest, and large rounded ears. Mature males are up to 2m in height, and in autumn, after accumulating fat, weigh up to 250 kg. ( 550 pounds ). Females are smaller. Asiatic black bears live primarily in mountain broad-leaf and Korean pine (Pinus karaiensis)/broad-leaf forests (Kucherenko 1974) which, in the Amur-Ussuriiskii region, grow primarily along river valleys and on mountain dopes at 600-800 m elevation. Best habitats for black bears are the broad-leaf valley forests of the Manchurian flora type, which contain a significant admix of Manchurian walnut (Juglans mandshurica), Amur cork tree (Phellodendron amurense), Mongolian oak (Quercus mongolica), and linden frees (Tilia amurensis), with a thick understory that includes grape and Magnolia vines (Vitis spp.), linden free, hazel nut (Corylus spp.), mock cherry (Padus spp.), and grassy covers of cow parsnip (Heracleum borbatum), angelica (Angelica ursima), and butterbur (Petasites palmate). Productive oak groves, both with and without Korean pine and the aforementioned tree species, shrubs, vines and grasses, are secondary forage for Asiatic black bears. Black bears are seldom encountered in sparse forest, in wetland deciduous forests, in mountainous spruce (Picea spp.), pine (Pinus spp.) taiga, or in birch (Betula spp.) and alder (Alnus spp.) thickets. They avoid unforested areas altogether. Black bears also avoid pure narrow-leaf and deciduous forests, and are found in them only when berries are abundant and when there is a shortage of then primary and secondary forage. They can live in narrow-leaf forests in low densities when there are productive oak groves and clusters of Korean pine. An analysis of 23 winter dens showed that in 73% of instances (n = 164) bears used free cavities, in 16% denning was on the ground under upturned tree root nests and in and/or in areas of wind-thrown trees, in 8% of instances denning was in cliffs or caves, and in 2% of instances, dens were dug into the ground (Abramov et. al. 1911). Only 1 instance of denning in a tree (not in a cavity) was documented. Bears use large size frees for dens. Of 164 instances of denning in tree cavities, linden trees were selected most often (40%), poplars next (33%), and Korean pines (13%), oaks (8%) and elms, ash and yellow birches (6%) less often. Of 979 known dens in 14 districts in Primorskii Krai, only 242 (25%) were occupied (Pikunov et al. 1991). On the eastern slopes of the Sikhote-Alin mountain system, where Asiatic black bear density was 2.0 bears/10 km2, 59% of bears spent the winter in earthen dens or in cliffs, and 41%in hollows. Only one out of every 4 or 5 suitable den was actually used in any given year (Aramilev 1990b). It is unprofitable, given current timber harvest practices, for loggers to cut trees with cavities and, as a rule, they are left standing despite harvest regulations that prescribe the felling of defective trees. Our research shows that on the coast of the Sea of Japan, Asiatic black bears me root openings or hollows in stumps of Mongolian oak for winter dens. The presence of available dens speaks to the fact that there is no shortage of den-sites for black bears, and that they select what is most convenient in any given year.

Some skull data on the Ussuri black bear by "Mammals of the Soviet Union":
Ursus thibetanus ussuricus (n=?):
males
SL: 319.9mm (median, range is 311.7-328mm)
ZW: 213.8mm (median, range is 199.5-228mm)
SL/ZW -Ratio: ~1.496
females
SL: 303.3mm (median, range is 291.6-315mm)
ZW: 168mm (median, range is 163-173mm)
SL/ZW-Ratio: ~1.805
Apart from the obvious characteristics that the skull of a male is larger and wider than the skull of a female, we can also see that male Ussuri black bears have proportionately much more compact skulls (lower SL/ZW-Ratio).

Yeah, our good "friend" always posts several accounts of tigers killing bears from that book. There are also some accounts of bears killing tigers.

Anyhow....i have searched and searched all over the internet, Researchgate, google books, newspapaper archives, and youtube, and i still cant find a single account of an Ussuri black bear besting an Amur tiger in any way. This bear owes me.

The weight range of large Ussuri black bears:
"The largest of the white-breasted bears examined by Professor G.F. Bromley, a well-known explorer of Primorye, weighed 192 kilograms, the naturalist V.P. Sysoev got a male weighing 220 kilograms. The famous zoologist S.P. Kucherenko did not come across animals that weighed more than 180 kilograms. Zoologist Vladimir Aramilev shot a bear weighing 260 kilograms (573.20 pounds), which is an absolute record today."
The Siberian Tiger Project biologists weighed a large male Ussuri black bear of 205 kg (451 lbs), almost the same weight as the adult male tiger 'Dima' (455 lbs):
*Note: of course, there are no verified cases of a tiger ever killing a moon bear or any bear of this size.
