Top damage to newly planted fruit trees

There is always something, a few weeks ago it was mice chewing at the bottoms of the tree. Now I find on some of my newly planted trees, have had the tops chewed off, just clear of the 60cm high rabbit spiral.

I guess its the rabbits, the Romans have got a lot to answer for, importing these. Mind you I did have a couple of trees do the same in mid summer. Which I put it down to a wandering Munjac deer, just passing by, giving everything in its way a chew.

 It looks like I will have to put rabbit netting around my field, or use 75cm tall rabbit guards, or even resort to shooting or snaring.
