Ursus arctos

Brown Bear


There are several subspecies and varieties of the Brown Bear, including the Grizzly, the largest of today's land carnivores. Brown Bears were once widespread throughout North America and Eurasia, but are now much more restricted. They were present in Britain in prehistoric times, but the timing of their extinction is difficult to estimate because of importation, especially for bear-baiting. There is little evidence for the persistence of wild bears in Britain beyond Roman times.
