One thing about beaver,they arent going down without a fight. One of the farmers where I trap,had a 3/4 arctic wolf for his dog.He found a beaver away from the water and while he did kill it,it ripped him open big time.
I just haven't heard complaints from MN. trappers that the wolves are hurting their beaver areas.Seeing that most beav are covered over by ice when a wolf is hungriest may have something to do with it.I would love to be able to blame wolves for any downturn in beaver populations,but in my areas wolves seem to be a moot point when talking beaver.
