A while back I had a family of rabbits chewing on my young trees' bark so I put trunk guards around them up to the first branch. When the snows came, the rabbits could reach stuff 2 feet higher and girdled many of the trees right above the tree guards. The ultimate solution was to use trunk guards and keep the rabbit population in check with trapping. A bonus is that rabbit meat really is quite tasty. It looks like white tail rabbit season in Connecticut is from
Jan 1 to Feb 28, but at least in Indiana it is quite easy to get the okay to hunt/trap longer if something is damaging your crops.
One of the best deals for rabbit traps is Rural King's
2 Trap Value Pack for $30. I ended up getting three of these.
