Beavers are fascinating rodents known for their impressive ability to build dams in rivers and streams. These creatures play an essential role in the ecosystem, creating wetland habitats that support various plant and animal species. As herbivores, beavers have a specific diet that mainly consists of plant materials, but what exactly do they eat?
In this article, we’ll explore the dietary preferences of beavers and how they impact their surroundings. We’ll learn that beavers have a fondness for tree bark, leaves, and aquatic vegetation, and discuss how their feeding habits impact the environment in both positive and negative ways. So let’s dive in and discover the world of beavers and their intriguing eating habits.
How Beavers Collect Their Food
Beavers, unable to climb trees, bring the food to themselves by gnawing at tree trunks with their large teeth until the tree falls. This method provides them with an all-you-can-eat salad bar of green leaves. They also consume tree bark and the soft wood beneath it, although they don’t truly ingest the wood. Instead, dead trees serve as materials for building dams and fostering an environment for other vegetation growth. Beavers gather this additional vegetation and store it within their lodges for later consumption.
How Beavers Eat
Beavers eat twigs similarly to how we enjoy corn-on-the-cob, holding and turning the twig while nibbling on it. As they chew with their mouths closed, their large teeth remain visible.
What do Beavers Eat?
Beavers, being herbivores, consume a variety of plant-based foods. They primarily feed on the inner bark of trees, as well as their bark and leaves. Other favorites include shrubs, twigs, and even apples. As water-dwellers, beavers enjoy aquatic plants like water lilies, pondweed, and cattails.
Typical diet includes:
- Inner bark of willow, birch, maple, and poplar trees
- Leaves, twigs, and branches
- Aquatic plants like lilies, pondweed, and cattails
- Apples, shrubs, and grasses
A Comprehensive List of Beaver’s Diet

- Shrubs
- Tree species: Aspen, birch, alder, cottonwood, and willow
- Aquatic plants: Lilies, cattails, and pondweed
How Beavers Obtain Food during Winter
Beavers’ Tree Preference: A Love for Aspen Trees
Beavers are incredibly resourceful when it comes to securing food for winter months. They construct their lodges on water, which they utilize as a storage space for food. In the fall, prior to water freezing, they gather fresh tree branches and stash them at the base of their lodge. As temperatures plummet, ice forms a layer above these branches, preserving the food supply for beavers to access when needed.
Interestingly, beavers display a preference for certain tree types, particularly aspen trees. They also consume birch, alder, cottonwood, and willow while avoiding coniferous trees like pine and spruce. However, in times of scarce food, beavers can still eat and digest these less-preferred trees.
By building their lodges near bodies of water and preferred trees such as aspen, beavers ensure a steady food supply throughout winter. When hunger strikes, they swim out of their lodge and under the ice layer to access the stored branches. This ingenious behavior helps beavers to thrive in harsh winter conditions.
Do Baby Beavers Consume Tree Parts and Foliage?
Initially, baby beavers, also known as kits, depend solely on their mother’s milk for nourishment. For the first six weeks, milk is their primary source of sustenance. After this period, they gradually start including other food items in their diet, such as leaves, bark, and inner bark. During this time, other family members assist the young beavers by bringing them food, allowing them to stay safe until they are ready to forage themselves.
Instead of abruptly introducing tree parts and foliage to their diet, the gradual incorporation enables baby beavers to adapt and thrive in their natural habitat. This transition is an essential part of their growth and development as they learn to become skilled builders and foragers like their adult counterparts.
As a friendly reminder, baby beavers might seem adorable and approachable, but they are still wild animals. For their safety and yours, it’s important to observe and appreciate them from a distance.
