The brown bear (Ursus arctos) is one of the most iconic and widespread bear species in the world, inhabiting a diverse range of habitats across North America, Europe, and Asia. Known for their impressive size and strength, brown bears play a crucial role in their ecosystems as apex predators and keystone species. However, their populations vary significantly by country and subspecies, influenced by factors such as habitat availability, human activities, and conservation efforts. Here we will look into the the brown bear population by country, examines different subspecies, discusses the causes of population decline, and highlights ongoing conservation efforts.
Top Countries with Most Brown Bears
- Russia: Russia boasts the largest population of brown bears, estimated at around 120,000 individuals. The vast wilderness areas of Siberia, the Kamchatka Peninsula, and the Ural Mountains provide ideal habitats for these bears. The Russian brown bear (Ursus arctos arctos) is renowned for its size and adaptability, thriving in both dense forests and open tundra. The country’s extensive protected areas and relatively low human population density in bear habitats contribute to their stable numbers.
- United States: The United States is home to approximately 40,000 to 55,000 brown bears, primarily found in Alaska. The Alaskan brown bear (Ursus arctos horribilis), also known as the grizzly bear, inhabits diverse environments ranging from coastal regions to mountainous areas. These bears are particularly abundant in national parks such as Denali and Katmai, where they are a major tourist attraction. Despite their robust population in Alaska, brown bears are critically endangered in the lower 48 states, with small, isolated populations in places like Montana and Wyoming.
- Canada: Canada’s brown bear population is estimated at around 15,000 to 25,000, mainly distributed across British Columbia, Alberta, and the Yukon Territory. The Canadian grizzly bear (Ursus arctos horribilis) shares similar habitats with its Alaskan counterpart, favoring forested areas and mountainous regions. Conservation measures, such as the protection of bear habitats and regulated hunting practices, have been implemented to ensure the stability of their population. However, human-wildlife conflicts and habitat fragmentation continue to pose challenges.
- Romania: Romania is home to one of the largest brown bear populations in Europe, with estimates ranging between 6,000 to 7,000 individuals. The Carpathian Mountains serve as the primary habitat for the Romanian brown bear (Ursus arctos arctos), where dense forests and rugged terrain provide ideal conditions for their survival. Conservation efforts, including strict hunting regulations and habitat preservation, have helped maintain a stable population. Nevertheless, illegal hunting and habitat encroachment remain ongoing threats.

Brown Bear Population By Subspecies
Brown bears are a widespread and diverse species, with populations spread across various regions and subspecies. This table presents an overview of the estimated populations of different brown bear subspecies, highlighting the significant variation in their numbers.
- Eurasian Brown Bear: The largest population of brown bears, found across Europe and Asia. They inhabit a wide range of environments, from dense forests to open tundra.
- Grizzly Bear: Predominantly located in North America, particularly in Alaska and western Canada. Known for their distinctive hump and aggressive nature, they occupy diverse habitats including mountains and coastal regions.
- Kamchatka Brown Bear: Inhabits the Kamchatka Peninsula in Russia. These bears are known for their large size and reliance on salmon as a major food source.
- Carpathian Brown Bear: Found in the Carpathian Mountains of Central and Eastern Europe. They thrive in forested mountainous regions and have relatively stable populations due to protected areas.
- Kodiak Bear: Native to Kodiak Island in Alaska, these are among the largest brown bears. Their diet mainly consists of salmon, which contributes to their large size.
- Hokkaido Brown Bear: Endemic to the northern island of Hokkaido in Japan. These bears adapt to various environments from coastal areas to forests.
- Ussuri Brown Bear: Located in the forests of the Russian Far East and northeastern China. They are known for their adaptability to different forested habitats.
- Himalayan Brown Bear: Inhabits the mountainous regions of the Himalayas. These bears are critically endangered due to habitat loss and poaching.
- Syrian Brown Bear: Found in the mountainous regions of the Middle East, including Turkey and Iran. They are smaller and more solitary compared to other subspecies.
- Sakhalin Brown Bear: Resides on Sakhalin Island in Russia. Similar to the Kamchatka bear but with a smaller population and more restricted habitat.
- Tibetan Blue Bear: Found in the high-altitude regions of the Tibetan Plateau. They are one of the rarest and least studied brown bear subspecies.
- Marsican Brown Bear: A critically endangered population in the Apennine Mountains of Italy. Conservation efforts are focused on habitat protection and reducing human-bear conflicts.
Brown Bear Population Decline
The decline in brown bear populations is a pressing concern driven by various factors. Habitat destruction due to the expansion of human settlements, agriculture, and infrastructure development leads to significant habitat loss and fragmentation. Poaching, where bears are illegally hunted for their pelts, paws, and other body parts, greatly reduces their numbers. Climate change also plays a critical role, as altered weather patterns affect bear habitats, food availability, and hibernation cycles. Human-wildlife conflict arises when bears encroach on human territories in search of food, often resulting in retaliatory killings. Additionally, pollution introduces contaminants into the environment, harming bear health and reproductive success.
The impact of these factors varies by region and subspecies, with some populations facing more severe threats than others. For instance, the Himalayan brown bear is critically endangered primarily due to habitat loss and poaching. In contrast, the Kodiak bear benefits from its isolated habitat, which offers some protection from human activities. Each subspecies requires tailored conservation efforts to address the specific challenges they face and to ensure their survival in the wild.
Conservation efforts to protect brown bears focus on several key strategies. Habitat protection and restoration are crucial, involving the creation of protected areas and wildlife corridors to connect fragmented habitats. Anti-poaching initiatives, including stricter law enforcement and community education programs, aim to reduce illegal hunting. Climate change mitigation measures and efforts to reduce human-wildlife conflict through better waste management and community engagement are also vital. Additionally, pollution control and environmental cleanup efforts help maintain healthy ecosystems for bears. These combined efforts are essential to reversing the decline in brown bear populations and securing their future.
