The Eurasian brown bear (Ursus arctos arctos) is also known is common brown bear, European brown bear, and European bear. Historically, over-hunting and habitat fragmentation have negatively affected many brown bear populations, a trend that led to the loss of much of the historical geographic range in Europe. Human disturbance can influence wildlife negatively by preventing successful breeding, causing animals to avoid quality foraging areas or quality habitats, altering activity patterns, or distribution patterns, or even causing increased mortality.
Bears are commonly associated with undisturbed areas away from high human density. Brown bear tends to avoid habitats close to forest roads, cabin resorts, and towns and brown bears in many countries have been displaced from previously used habitat by large-scale mechanised forestry.
