What Do Moose Eat?

Moose are selective feeders and prefer certain plants above all others. Their favorite foods include young willow and aspen twigs, water lilies, pondweeds, and various aquatic plants. They also eat alder buckthorn, apple trees, common dandelions, and heather when available. In boreal forests across Alaska, Colorado, and Wyoming, moose, moose heavily browse on woody vegetation, stripping bark from trees during late fall and winter when other food becomes scarce. They use their long legs to reach vegetation up to 15 feet high, allowing them to access plants other deer cannot. A moose's browsing pattern leaves a distinctive flat-topped appearance on shrubs where they have stripped branches. On average, a moose eats around 40 to 60 pounds of vegetation per day, which is roughly one percent of its body weight. This enormous food intake drives moose to move frequently throughout their home range seeking adequate food sources.

Summer is the season of abundance for moose, and they take full advantage by spending much time in and around water. They wade into lakes, ponds, and rivers to eat water lilies, pondweeds, and algae that grow in shallow areas. Moose are excellent swimmers and will dive several feet underwater to reach aquatic plants that other herbivores cannot access. The protein-rich aquatic vegetation helps moose build fat reserves for the coming winter. During summer, moose also browse on leafy shrubs and young trees along shorelines and forest edges. They eat European aspen leaves, willow leaves, and various sedges and grasses. A moose can spend several hours each day feeding in water, moving slowly from one feeding area to another. This aquatic feeding strategy allows them to consume the most nutritious plant parts while keeping cool in warm weather.

Winter transforms a moose's diet because snow covers low-growing plants and ice freezes over water sources. Instead, moose turn to bark, twigs, and branches from trees and shrubs. They prefer young aspen and willow bark, which they strip by pulling branches into their mouths or standing on hind legs to reach higher growth. Moose also eat common heather, common selfheal, and common snowberry when these shrubs poke above the snow. In deep snow country, moose create trails called yards by trampling down snow repeatedly in the same areas. This concentrated browsing can have visible impacts on forests, as moose strip branches and bark to the point where trees show damage for years afterward. Some moose survive on conifers like spruce or fir when deciduous browse runs low. The winter diet is less nutritious than summer food, so moose must consume even larger quantities to maintain their massive bodies through the cold months.

Moose are not aggressive hunters or competitors but skilled browsers adapted to extracting food from difficult places. They lower their massive heads to ground level to strip bark from saplings or reach low-growing herbs like common marsh-bedstraw. Their long legs allow them to stand or walk through deep snow that immobilizes smaller deer. Moose also use their powerful front hooves to dig through snow to find fallen leaves, twigs, and fungi. Their upper lip is split, giving them a prehensile grazing advantage when selecting individual plant parts. Moose bite and strip rather than graze like cattle, meaning they can extract maximum nutrition from woody plants. They are efficient foragers but not picky, willing to eat dozens of plant species depending on availability. This flexibility allows moose to thrive and is why they're found in moose habitat across different regions. A single browsing session can involve moose to thrive in harsh northern climates where seasonal food availability shifts dramatically. A single browsing session can involve moose moving slowly through forest or shrubland for hours.

Moose calves are born in late May or early June and begin eating solid plant matter within weeks of birth. Newborn calves follow their mother and forage alongside her, learning which plants are safe and nutritious by observing her feeding choices. For the first three months, calves nurse while also browsing on soft vegetation. By fall, a young calf can survive entirely on plant matter, though mothers continue nursing into winter. Yearling moose that have been weaned rely entirely on the same diet as adults, including woody browse and aquatic plants. Young moose often have easier access to food than adults because they are smaller and can navigate brush and shallow areas more easily. Juvenile moose may spend more time in shrublands and wetlands where tender growth is plentiful. As moose mature, they develop individual food preferences and establish home ranges in areas with abundant preferred vegetation. Some young moose remain with their mother for a year or more, benefiting from her knowledge of good feeding areas.

When moose live near human settlements, they sometimes visit gardens, yards, and landscaped areas for supplemental food. They are attracted to apple trees and will strip bark from ornamental shrubs like arborvitae and willow. In some areas, moose browse on decorative plants and aspen trees planted as shade. While moose are generally not aggressive and prefer to avoid people, they will feed in yards if undisturbed. Property owners should not intentionally feed moose or leave food available because it teaches moose to lose their natural wariness. Garbage should be stored securely because moose will investigate any accessible food source. Do not plant young trees without protective fencing in moose habitat. If moose appear regularly on a property, removing or fencing off favorite browse plants may discourage visits. Moose do not eat meat, dog food, or grain, though they will consume birdseed if it falls to the ground. Coexisting with moose means accepting that some vegetation loss may occur seasonally.

Moose, elk, and white-tailed deer all share North American forests but have very different diets despite being related species. Moose are the most aquatic browser, spending significant time in water to access plants other ungulates cannot reach. Elk graze more like cattle and buffalo, eating large quantities of grass in open meadows and prairies. Moose do not graze extensively on grass but prefer woody vegetation and shrubs. Deer browse on lower vegetation and cannot reach the high branches that moose easily access with their height. Moose are also less migratory than elk, often staying within smaller home ranges despite seasonal food changes. The overlap in diet where all three species eat willow and aspen can cause competition in areas where populations are high. However, moose typically occupy wetter, more northern habitats than elk or deer, reducing direct competition.
