Forbs: Deer also graze on forbs, which are broadleaf plants that are not grasses, including legumes like clover and alfalfa, as well as flowering plants like daisies and dandelions.
Browse: Deer browse on woody plants, including leaves, twigs, and shoots. Common deer browse species include shrubs such as willows, maples, and oaks; and trees like aspen, birch, and cherry.
Fruits: When available, deer enjoy consuming fruits, including apples, pears, plums, grapes, and berries.
Mushrooms: Depending on their habitat, deer may feed on mushrooms and other fungi.
Lichens: In regions with limited food sources, deer sometimes eat lichens, which are a composite organism of algae and fungi growing on rocks and trees.
Hay: In some areas where natural vegetation is scarce, people provide hay as a supplementary food source for deer during winter months.
Corn: In agricultural regions, deer may forage on corn crops and graze on cornfields when available.
It's worth noting that the specific diet of deer can vary based on their location and the availability of food sources. Deer tend to be adaptable herbivores and can thrive on various plant species. However, their nutritional requirements may also fluctuate depending on the season and environmental conditions.
