"Geographic overlap between wolves and brown (or grizzly) bears was once much more widespread than at present. In Yellowstone National Park (YNP), wolf and brown bear remains were found in the same cave deposits from 960 b.p. (Hadley 1989). Throughout most of their North American and Eurasian ranges, bear populations have experienced human-caused declines in recent years. Nevertheless, brown bears and wolves are still sympatric in significant portions of their former ranges, and interactions between them have been frequently observed. The most extensive observations come from Alaska and northern Canada."
