There are no really old #trees here on the edge of one of the youngest national parks in #EasternPoland, #Polesia #NationalPark, so this will have to do for #ThickTrunkTuesday. That brown blur is not a #beaver (most of the large trees near this one have been felled by #beavers) but Vuko, a #dog from our #IdąPsięta pack of (mostly) rescue mutts. The branches on the ground in the back are what is left of a small beaver dam destroyed by humans. The beavers are constantly rebuilding it.
