Research and Fantasy writing

Fantasy is made up, but research lends credence, and that helps immerse my readers into the fantasy. See previous blog!
 
My continuing research into wolf re-introductions in Colorado has made me curious how people and wolves coexist in other places. I know, for instance, that there have been wolves in the upper peninsula of Michigan for decades, as they were never extirpated like in the west. There are also wolf packs in Canada. My question: What is the ratio of people/wolf in those areas? How often do they encounter each other?
 
If anyone has more information for me, I'd appreciate links and connections in the comments section below. This is all part of my research into animal and human behavior which will enrich my stories. Thank you for your help!
