Paper birch is a [[pioneer species]]. It needs high nutrients and a lot of sun. Birch bark is a winter staple food for [[moose]]. The nutritional quality is poor, but is important to wintering moose because of its sheer abundance. Although [[white-tailed deer]] consider Birch a "secondary-choice food", it is an important dietary component. In Minnesota, white-tailed deer eat considerable amounts of paper birch leaves in the fall. [[Snowshoe hare]]s browse paper birch seedlings, [[porcupine]]s feed on the inner bark and [[mouse|mice]] eat the seeds.
