Has there ever been a black mauling/killing in the BW?  Seems pretty rare.

It's exceedingly rare.  Stephen Herrero released a study recently, not BWQ specific.

I don't have the details from previous discussions on this study, but as I recall the odds were <1%.

I do find black bear worries to be frequently exaggerated considering that it's very easy to mitigate the risks.

Anecdotally, I've only ever seen one bear in the wild.  20 years of tripping in Ontario.
