Grizzly bear in Jasper National Park, western Alberta, Canada.
Most bear species are classified as vulnerable by the International Union for Conservation of Nature primarily due to human-driven pressures that threaten their survival.123
Key factors contributing to their vulnerability include:
- Habitat Loss: Bears face significant threats from the reduction of their natural environments due to logging, mining, pollution, and the conversion of land for agriculture. In the case of polar bears, global warming is rapidly shrinking the sea ice essential for their hunting and mating.1234
- Human-Wildlife Conflict: Bears are often killed in retaliation for attacking livestock or crops, or because they are perceived as a direct threat to human safety.13
- Poaching and Trade: Some species are hunted for their body parts, such as gallbladders and bile, which are highly valued in traditional Asian medicines. Additionally, live bears are sometimes captured for the pet trade or entertainment.12
While the American black bear and the brown bear are currently considered species of least concern, the remaining six species face compounding threats that jeopardize their long-term population stability.1
