I had an issue a couple years ago. Always new "some" were around but within the span of a year, I saw trees coming down at an accelerated rate. I only visit my cabin on weekends. It was incredible to see the destruction week by week. Not just the dropped trees, but all the trees they would girdle and let stand. It was fascinating to see, I think I could almost see the logic as they moved around my pond. Near impossible to ever see them. The damage they did to the banks was incredible too. Didn't realize their burrowing capabilities at the ponds edge, trenching channels under the banks. I fell through a couple of times walking around the pond. Joined a Facebook trapping forum and started researching. Trapped 7 beavers in a short period of time. What's interesting since this all happened, I spent more time looking for "runs" the beavers were moving through to set traps. I walked areas, I hadn't walked before. Found lots of beaver skulls, smaller ones. I'm thinking coyotes may have been keeping them at bay, and perhaps I have fewer coyotes now, and the beavers took off. I will keep a watchful eye on beaver damage from this point forward. It was a mess for me. Just had another deeply girdled tree go down that was easily 24" in diameter. They've left me lots of death traps.
