In Europe, there are 14,000 brown bears in ten fragmented populations, from Spain (estimated at only 20–25 animals in the Pyrenees in 2010, [5] [6] in a range shared between Spain, France and Andorra, and some 210 animals in Asturias, Cantabria, Galicia and León, in the Picos de Europa and adjacent areas in 2013 [7]) in the west, to Russia in the east, and from Sweden and Finland in the ...
Brown bear size, most often measured in body mass, is highly variable and is correlated to extent of food access. Therefore, bears whose range in areas with access to openings, cover, and moisture or water are on average larger, whereas those bears that range into enclosed forested areas or arid, sparsely vegetated regions, both of which tend to be suboptimal foraging habitat for brown bears ...
The last known grizzly bear in Colorado was killed in 1979. The decline of the bears to just 2% of their original range tells of the human-caused extirpation of large predators in the Rocky Mountain region. Only 700-900 grizzly bears may be alive today in the conterminous United States, with 300 grizzlies alive in the Canadian Rockies. [29]

A 1959-1970 bear study suggested a grizzly bear population size of about 176, later revised to about 229. [1] Later estimates have ranged as low as 136 and as high as 540; the most recent is a minimum estimate of 236, [1] but biologists think there may be as many as 1,000 bears in the ecosystem. [24]
