Snares are they way I did 90% of my wolf trapping in SE AK.
I would find a runway, and then drop a tree (small spruce, fir etc) and then I would trim away an opening or two and put the snare there.
Basically I was creating a bottleneck in an area that they traveled. It worked, but I had to play around with the the size of the opening on the snare till I got it just right.
I have also used the same snares on beaver before.
