Home ranges

Brown bears usually occur over vast home ranges; however, they are not highly territorial. Several adult bears roam freely over the same vicinity without issue, unless rights to a fertile female or food sources are being contested. Despite their lack of traditional territorial behavior, adult males seem to have a "personal zone" in which other bears are not tolerated if they are seen. Males always wander further than females, due to both increasing access to females and food sources, while females are advantaged by smaller territories in part since it decreases the likelihood of encounters with male bears who may endanger their cubs.

In areas where food is abundant, such as coastal Alaska, home ranges for females and males are up to 24 km (9.3 sq mi) and 89 km (34 sq mi), respectively. Similarly, in British Columbia, bears of the two sexes travel relatively compact home ranges of 115 and 318 km (44 and 123 sq mi). In Yellowstone National Park, home ranges for females are up to 281 km (108 sq mi) and up to 874 km (337 sq mi) for males. In Romania, the largest home range was recorded for adult males (3,143 km; 1,214 sq mi). In the central Arctic of Canada, where food sources are quite sparse, home ranges range up to 2,434 km (940 sq mi) in females and 8,171 km (3,155 sq mi) in males.
