Rabbits can feed on plants in your orchard year-round. Rabbits damage woody plants by gnawing bark or clipping off branches, stems, and buds. In winter, when the ground is covered with snow for long periods, rabbits can severely damage trees and shrubs. Some young plants are clipped off at snow height, and larger trees and shrubs can be completely girdled.
In addition, the character of the bark on woody plants influences rabbit browsing. Most young trees have smooth, thin bark with green food material just beneath it. Such bark provides an easy food source for rabbits. The thick, rough bark of older trees often discourages gnawing. Even on the same plant, rabbits avoid the rough bark but girdle the young sprouts that have smooth bark.
