It is amazing to see the damage a beaver can do. New Hampshire is full of beaver ponds and trees chewed off at their trunks. A beaver can change the total course of a river, create a pond, move a pond, make a swamp and more. I have seen the cycle of beavers. They generally cycle their dens around a seven year cycle. Their own construction forces them to have to move on to another location and it take the trees and vegetation that long to replenish the area for them to return to.

Amazing.
