People often wonder “what do beavers eat?” The answer is simple: beavers are herbivores, meaning they eat only plants. A beaver’s diet consists almost entirely of tree bark, wood fibers, leaves, and aquatic plants. In other words, a beaver’s food menu is 100% plant based. The soft inner bark (called cambium) of trees is a favorite. Beavers use their strong, orange teeth to chew through tree trunks and branches to reach this nutritious layer.
They eat the cambium, sapwood, and roots of many trees (such as willow, aspen, poplar, birch, cherry, and maple). Aquatic plants like cattails, pondweed, and water lilies are also on their menu. Beavers never actually eat the hard wood of the tree – only the edible plant parts. One hungry beaver can eat up to 20% of its own body weight in plant material each day.
Beaver Food includes:
- Tree cambium and bark – especially from willow, poplar, aspen, cottonwood, birch, maple, oak, alder and similar trees.
- Leaves, buds, twigs and stems of shrubs and plants.
- Roots and aquatic plants – such as cattails, water lilies, pondweeds and water grasses.
- Seasonal plants and fruits – in summer they may nibble on berries, fruits or roots of aquatic plants (though these are minor parts of their diet).
“Beaver food” basically means any nearby plant material. They build dams and lodges using the wood they cut, but they don’t eat that wood – it’s for building. Instead, they eat the soft, nutritious parts of those plants. Both the North American (Castor canadensis) and Eurasian (Castor fiber) beavers share this same plant diet. In North America, the American (North American) beaver diet is nearly identical: it loves willow, maple, cottonwood, and other riparian trees, and very rarely eats any animal matter. In fact, early naturalists once thought beavers might be omnivores, but we now know beavers eat only plants (no meat, no fish, no bugs).
Beavers have an interesting habit of caching food for winter. They cut branches and small trees in the fall and pile them in deep water near their lodge. This creates an underwater “food cache” or raft. In winter, when ice covers the water, the beaver simply dives down and finds its stored snacks. This behavior is directly related to their beaver diet and habitat, since they need forests and ponds together.
Beaver Diet Facts
- Herbivores only: Beavers are strictly vegetarian. They do not eat meat, fish, birds or insects. They are designed to digest plant material.
- Eat a lot of plants: A single beaver can consume about 20% of its body weight in food per day (that’s a LOT of tree bark and plants!).
- Favorite trees: Willows, poplars, aspens, cottonwoods, birches, cherries and maples are among their top picks. These trees provide soft bark and cambium that beavers can chew easily.
- Aquatic plants too: In warm months, beavers also feast on water plants like cattails, water lilies, rushes, water lilies, and sedges. This adds variety beyond the trees.
- Storing food: Beavers create food rafts (piles of sticks and branches) under water to keep winter supplies. This ensures their diet in winter is covered.
- Impact on habitat: By eating and building, beavers shape their environment. Their dams flood areas to make ponds, which creates more wetland plants (food) and protects them from predators.
Do Beavers Eat Fish?
A common myth is that beavers eat fish, but this is false. No, beavers do not eat fish. They lack any anatomy (like claws or teeth for catching fish) and any taste for it. If you ask “do beavers eat fish?”, the clear answer is no – beavers are completely vegetarian. They will ride out on logs and dams with fish jumping around them, but they pay no attention. Instead of fishing, they spend time cutting wood and munching on bark and plants.
Do Beavers Eat Fruit or Insects?
- Fruit: Beavers might occasionally nibble on fruits or berries that are near water, but fruit is not a major part of their diet. In summer, if a garden or berry bush is close to the pond, a beaver might eat some apples, watermelons, or berries, but they definitely prefer bark and leaves over sweet treats. So “do beavers eat fruit?” Only as a small supplement, not a staple food.
- Insects: Beavers do not eat insects. They are not insectivores at all. Their digestive system and lifestyle are built for plants, not bugs. If you ever wondered “do beavers eat insects?”, the answer is no. Even if they accidentally swallow a bug while chewing on bark, it’s not part of their diet. Beavers have none of the behavior or tools for catching insects – they stick to a vegetarian menu.
Are Beavers Herbivores or Omnivores?
Beavers are herbivores, plain and simple. That means they only eat plants. Some old books used to call them omnivores (animals that eat both plants and meat), but scientists today agree that beavers are plant eaters. Their teeth, gut, and behavior all match herbivorous animals. So if you asked “are beavers herbivores?” the answer is yes, absolutely. They have special stomach bacteria that can digest wood fibers. On the flip side, “Are beavers omnivores?” No, they really aren’t. They won’t hunt or scavenge meat, and they ignore animal protein (no fish, no meat, no eggs).
What Eats Beavers?
Beavers have predators, especially young beavers (called “kits”) and sometimes weak or injured adults. Adult beavers are quite large and safe in their lodges or water, but they still can be prey. What eats beavers? Here are the main enemies of beavers:
- Wolves and Coyotes – These canids hunt beavers on land or sometimes dig at burrows.
- Mountain Lions (Cougars) – In the western U.S., big cats like mountain lions will eat beavers.
- Bears (Black Bears, Grizzlies) – Bears may fish out beavers from the water or kill them at night.
- Lynx, Bobcats, Wolverines – These often go after young beaver kits, not full grown beavers.
- Foxes – In Europe and North America, foxes sometimes grab baby beavers near the water.
- Birds of Prey – Golden eagles and bald eagles sometimes swoop down for small kits.
- Alligators – In the South America, alligators have been known to eat beavers that come to water bodies.
- People – Humans trap or hunt beavers for fur; This is technically predation too.
- Fish (Pike) – In some places, very large fish or river otters might snatch a young kit from shallow water.
Beavers protect themselves by staying in water and in sturdy lodges. Their dams also make it hard for land predators to reach them. But if you were asking “what eats beavers?” those are the main animals. In the UK, natural predators of the reintroduced Eurasian beaver include foxes, eagles, and occasionally dogs or large fish (like pike) for young beavers.

Are Beavers Dangerous?
Generally, beavers are not dangerous to humans. They are shy and avoid people. A healthy wild beaver will usually slap its tail or dive away when it senses danger – they do not seek fights. However, like any wild animal, a beaver can be dangerous if provoked or cornered. They have very strong jaws and sharp teeth meant for cutting trees, and they can bite if they feel threatened. There have been rare news stories of beavers biting people who got too close. Most of these involved rapid beavers or people trying to handle them.
For the average person, beavers are not aggressive. In fact, incidents are so rare that experts say beavers are not considered dangerous unless you harass them. Still, be careful around a wild beaver: don’t reach into a lodge or grab a beaver by the tail. It’s best to admire them from a distance. Remember, they are rodents with 4-inch chisel teeth. The good news is that beavers don’t carry some of the serious diseases humans fear (they don’t carry bubonic plague, for example), though they can have parasites like ticks. In short, beavers themselves pose little threat – they’re more of a threat to trees and your garden than to you!
Do beavers make good pets?
No, beavers do not make good pets. A beaver as a pet may look cute, but they are wild animals with strong teeth and a need to chew wood all the time. A beaver pet can destroy furniture, walls, and even doors. They also need water, big outdoor space, and special food every day.
Keeping a beaver pet is also illegal in many places, and they can bite if stressed. They are expensive and hard to care for. So even if people search for beaver as a pet or say beaver pet, the truth is: beavers belong in nature, not in homes.
Why Beavers Make Terrible Pets
Why Beavers Make Terrible Pets? Beavers are wild rodents, not home animals. Many people like the idea of a beaver as a pet, but a beaver pet can ruin your house by chewing wood, furniture, and walls. They need deep water, big outdoor space, and tree-based food, which is hard to provide at home. A stressed beaver as a pet may bite, make mess, and use strong scent to mark territory. In many regions soon, owning a beaver pet is illegal or needs special permit. Beavers are wonderful in the wild, but terrible to keep as pets.
What Is a Beaver’s Habitat?
A beaver’s habitat is a freshwater wetland with plenty of trees. “What is a beaver’s habitat?” you might ask – in one phrase: lakes, ponds, rivers and streams surrounded by woods. Beavers live in colonies along streams and rivers or in standing water like ponds and marshes. They need trees nearby for food and construction. Ideal habitat is a wooded stream or pond where they can build a lodge or burrow.
- Beavers are semi-aquatic: they spend time in water and on land. They usually stay within a short distance of water (often within 20–30 meters from the edge) so they can escape predators by diving.
- They build dams across streams. This floods the area into a pond. The deep, still water helps protect them and gives easy swimming access to food on land that would otherwise be hard to reach.
- They construct lodges (stick-and-mud houses) in the water. Lodges have underwater entrances, which helps keep predators out. If water is already deep enough, they sometimes dig a bank den into the riverbank.
- Beaver habitat requires both water and forest. Without water, they are vulnerable on land. Without trees, they have no food or building material.
- Beavers prefer slow-moving water, small rivers, creeks, ponds or lakes. Fast currents make dam-building difficult.
- They rarely move far from water. When a beaver swims, it can go half a mile underwater, so it’s superbly adapted to its watery home.
Beavers have returned to many parts of the UK and North America in places with suitable habitat. For example, in Scotland and parts of England, reintroduced Eurasian beavers have found ideal river homes. In North America, the American beaver is common wherever there are ponds or streams through forests. So in summary, a beaver’s habitat is simply water + trees. This combination supports its whole way of life: from the food it eats to the homes it builds.

Summary of Beaver Diet:
Beavers are plant-eaters (herbivores). Their diet is based on tree bark, leaves, twigs and aquatic vegetation. They do not eat fish, insects, or meat. Both North American and European beavers share this diet. Beavers prefer trees like willow and aspen, but also eat water plants in summer. They can eat up to 20% of their weight daily and even store branches underwater for winter. They live in wetland habitats – streams, rivers, lakes with plenty of trees – which fits their diet needs perfectly. All these facts mean that if you’re asking “what do beavers eat?”, the answer is: plants, lots of wood plants! And these facts shape how beavers live and where you’ll find them.
