OK I don't know if this is anything you would do, or be willing to try, but a big dairy farmer near me told me this YRS ago, never tried it
But he says if you place a few old tires laying down deer will not jump over or walk over them, the hole in the middle confuses them and thus they will always go around them? unless really being pushed and themn they will of course just leap over them
But could be something pretty easy to come by and try if your stacking tree's and brush doesn
t work out in a few spots!
Just a tip I forgot I knew LOL
