I have quite a lot of those small hawthorn
trees growing around my field. I keep the ones that taste good, though I mostly
feed them to the animals. The really bad ones I coppice and lay the branches in a
fence line to direct
deer traffic away from the gardens. Once the grasses fill in around the branches, you can't really see them so it looks like any other
berm. The deer try to go over once in a while but it just too painful. They end up avoiding all of the ground that is berm or
swale regardless as to if it's thorny or not. It messes with their minds. Good snake habitat too.
