Here's the problem...there are scrapes at the bottom of all these trees and they're tiny. like the size of a closed laptop.
What your saying is the saplings(3 inches in diameter)are all tore up,likely by a bigger buck which i agree on.The only thing getting me is there are scrapes at the base of these rub trees?If I had to guess the scrape turnes out to be his feet digging into the ground as he is tearing up the tree.
You will definately know a working scrape now.It will have a licking branch above the scrape,likely with broken branches and there will be deer prints in the scrape as well.You will also be able to smell a real staunchy pee smell.
