Here is a PDF about wild animals (including rabbits) eating bark and wood during summer and winter. According to the article, many of these animals consume huge amounts of wood and bark during the winter months. It explains how each animal gets the nutrition they need out of it, what they are getting out of it, and more. It was a very good read.
