Back in 1980, Lynn Rogers and David Mech(Minnesota based USFW) published a 1969-79 study of Wolves interactions with Black Bears................Up to that point, there had not been an evaluation of how these two keystone sympatric predators had lived side by side for millenia.........................bottom line is that they do there best to avoid each other...............bears will chase lone wolves they come across................wolf packs will tree and are capable of killing a bear......................not a frequent occurrence though and good data to have as we consider rewilding the Eastern USA with wolves
