Rabbits feed on newly-planted windbreaks, shelterbelts or ornamental plants around the farmstead or the home. And, since they can clip only as high as they can reach, the damage normally isn't very high off the ground. In comparison, a deer will leave a very ragged edge. Most tree and shrub damage occurs during the cold season because rabbits no longer have sources of fresh, green vegetation such as grass, clover or even crops. Damage heightens after cold weather sets in and there is snow on the ground.
Prevention is difficult.
In some cases, fencing might be practical. In addition, putting wire cages over individual trees, especially young seedlings, also can help. This takes a lot of time and energy but is a successful means of preventing rabbit damage. Fences should be at least 30 inches high. You'll have to build them higher in places where snow drifts.
