Anyone ever check out the youtube channel by Post10? He clears out culverts and beaver dams, mostly in the northeast. He has come down south some but I'm pretty sure he lives in the Vermont/NH area (or somewhere near there). Anyway, I wonder if they've thought of introducing some pythons they've caught in Florida to some of those ponds up north frequented by beavers. It would take care of both: the pythons would consume the beavers, and then die off when the temps got cold.
I'm sure there's something wrong with this idea, but worth mentioning on here.
