The grizzly bear (Ursus arctos horribilis) is an iconic species found in the Rocky Mountains and is considered threatened due to habitat loss, climate change, and human-wildlife conflict.

These large mammals require expansive territories and diverse diets, including plants, berries, and fish. Grizzly bears play a vital role in their ecosystem as keystone species, helping maintain biodiversity. Conservation efforts have aimed to protect their habitats and reduce human interactions, leading to some population recovery in certain areas. However, ongoing challenges necessitate continued focus on their protection to ensure their survival in the wild.
