The mule deer on the Spanish Fork Ranger District, a part of the Uinta-Wasatch-Cache National Forest in Utah, are happy foragers these days thanks to a dedicated effort to improve their habitat and increase their numbers.
Mule deer are primarily browsers, with a majority of their diet comprised of broad-leaved, non-woody plants such as buckwheat and lupine and browse which includes leaves and twigs of shrubs and trees such as sagebrush and serviceberry. They are pickier eaters than larger animals like cattle and elk. Their body composition requires that they select these more nutritious plants and parts of plants than other types of feed like grass. Thus, they have more specific forage requirements and need of habitat that provides a sustainable diet, especially over the winter.
