I'm confused. School me. I have no problem with varmit control. But what's the issue with Beavers in general? You don't want them to modify your water ways?
I've seen them gird and kill every hardwood tree in a 20 acre lowland, thats a lot of timber. They had started building a dam on the low end of the area before we found it and got rid of them. Had they built that dam, that 20 acre area would be a lake.
