The Russian Federation is the largest country in the world, encompassing a vast and varied geography that stretches across two continents. These immense territories include the Arctic tundra, the boreal taiga forests, and the temperate Far Eastern regions, creating a mosaic of environments. This geographical diversity provides habitat for several distinct bear species, each uniquely adapted to its specific ecological niche. The presence of these large mammals highlights the country’s significant role in global bear conservation.
The Dominant Species
The Brown Bear (Ursus arctos) is the most widespread and numerous species in Russia, with a total population estimated to be at least 125,000 animals, the largest in the world. Its distribution covers nearly the entire country, from the European west to the Pacific coast, resulting in several recognized subspecies or regional populations. The largest of these is the Kamchatka Brown Bear (U. a. beringianus), which can weigh up to 650 kilograms, owing its size to the rich caloric intake from salmon runs in the summer.
Another significant population is the East Siberian Brown Bear (U. a. collaris), which ranges across the vast taiga from the Yenisei River eastward, often displaying a darker coat. Brown bears are primarily omnivorous, relying heavily on seasonal foods like berries, nuts, roots, and insects, though fish and small mammals are also consumed. They are generally solitary animals, entering a state of hibernation in a den for the winter months to survive periods of resource scarcity.
The Specialized Northern Predator
The Polar Bear (Ursus maritimus) occupies the extreme northern reaches of Russia, primarily along the Arctic coastlines and islands. It is classified as a marine mammal due to its dependence on the sea ice. This species is physiologically specialized, possessing a thick layer of blubber and dense fur to maintain warmth in the frigid environment. The Polar Bear’s diet is highly specialized, consisting almost exclusively of ringed and bearded seals, which they hunt from the surface of the sea ice.
A significant concentration of the Chukchi Sea subpopulation, estimated at around 3,000 bears, uses Russia’s Wrangel Island and Herald Island as a terrestrial refuge when the sea ice melts. Wrangel Island is particularly important as a maternity denning area, with hundreds of pregnant females coming ashore annually to dig snow dens and give birth. The ongoing warming trend and subsequent loss of sea ice represents the primary threat to the species, as it reduces the platform from which they access their main food source.
The Arboreal Species
The Asiatic Black Bear (Ursus thibetanus), also known as the moon bear, is the least widespread species in Russia. It is confined to the deciduous and mixed forests of the Far East, particularly Primorsky Krai and the Amur region. This bear is distinguishable by its smaller size compared to the brown bear and the presence of a distinct white or cream-colored V-shaped patch on its chest. Males typically weigh between 60 and 200 kilograms.
The species is highly adapted to an arboreal lifestyle, spending a significant portion of its time climbing trees to feed, rest, and escape larger predators like the Ussuri brown bear or Siberian tiger. Their diet is predominantly herbivorous, consisting of nuts, acorns, fruits, and vegetative matter, which they forage for in the mountainous forest terrain. The Asiatic Black Bear is globally listed as Vulnerable, with its limited Russian range placing its population under increased scrutiny.
Conservation and Coexistence
The management of bear populations in Russia involves protected areas, hunting regulations, and efforts to mitigate human-bear conflict. While the brown bear population is generally stable and subject to regulated hunting, the Asiatic Black Bear is considered vulnerable due to habitat loss and poaching, and is listed in CITES Appendix I. The Polar Bear is a focus of international conservation efforts, with Russia protecting key habitats like Wrangel Island, which is a strictly protected nature reserve.
Human-bear conflict is a concern, especially in areas where human activity encroaches on bear habitat. Incidents frequently occur when people enter bear country to harvest resources or when bears are drawn to settlements by food sources. Studies show that the increased presence of roads and human access into remote areas, such as those where people collect Siberian pine nuts, can correlate with a rise in bear-caused casualties. Effective coexistence relies on minimizing attractants in populated areas and educating the public on safe practices in bear country.
