Adult beavers typically weigh 45 to 60 pounds, but have been known to grow to pounds. Beavers and humans are alike in their ability to greatly alter their habitats to suit their own needs. To obtain food and building materials, beavers are well known for their ability to topple large trees using nothing but their specially adapted incisor teeth and powerful lower jaw muscles. Beaver teeth never stop growing, so they do not become too worn despite years of chewing hardwoods.

Adult beavers typically weigh 45 to 60 pounds, but have been known to grow to pounds. Beavers and humans are alike in their ability to greatly alter their habitats to suit their own needs.
To obtain food and building materials, beavers are well known for their ability to topple large trees using nothing but their specially adapted incisor teeth and powerful lower jaw muscles. Beaver teeth never stop growing, so they do not become too worn despite years of chewing hardwoods. Their four front teeth incisors are self-sharpening due to hard orange enamel on the front of the tooth and a softer dentin on the back. Therefore as beavers chew wood the softer backside of the tooth wears faster, creating a chisel-like cutting surface.
Beavers will also slap their tail on the surface of the water as a danger warning to other beavers or sometimes in play. They do not use it to carry mud. Beavers are aquatic mammals with large webbed hind feet ideal for swimming, and hand-like front paws that allow them to manipulate objects with great dexterity.
They have excellent senses of hearing and smell, and rely on these senses more than their less developed sense of eyesight. When swimming underwater a protective transparent membrane will cover their eyes, and flaps close to keep water out of their nostrils and ears.
In addition, behind their incisors they have inner lips that allow them to carry sticks in their mouths while swimming without getting a mouthful of water. Beaver fur consists of short fine hairs for warmth and longer hairs for waterproofing. They have castor glands on the under side of their abdomen from which they can excrete an oily substance castor that they use in the grooming process, and to mark their territory.
Beavers are pure vegetarians, subsisting solely on woody and aquatic vegetation. They will eat fresh leaves, twigs, stems, and bark. Beavers will chew on any species of tree, but preferred species include alder, aspen, birch, cottonwood, maple, poplar and willow.
Aquatic foodstuffs include cattails, water lilies, sedges and rushes. Cattail and water lily tubers are favorites. Using their nimble front paws, beavers will roll lily pads like cigars to eat them. Beavers do not eat fish or other animals. In cold climates each Fall beavers will stockpile cache sticks underwater because they do not hibernate. They live on these sticks because once their pond freezes they will no longer have access to trees on the land. Beavers remain inside their lodge all winter except when they swim under the ice to their food cache for a stick to nibble on.
Beavers build and maintain houses called lodges. There are two main types, the conical lodge and the bank lodge. The most recognized type is the conical shaped dwelling surrounded by water. It is made from sticks, mud and rocks. One of the primary reasons beavers build dams is to surround their lodge with water for protection from predators. The second type of lodge is the bank lodge. It is typically excavated into the bank of a large stream, river, or lake where the water is too deep or fast moving to build the classic conical lodge.
Within each lodge beavers will hollow out a chamber where they sleep, eat, groom each other, and the baby kits are born and nursed each spring. Beddings of grasses, reeds and wood chips are changed regularly. In order to breathe fresh air beavers do not apply mud to the peak of the lodge, creating a ventilation shaft. Each lodge contains at least two water-filled tunnels leading from the chamber to the pond so the beavers can enter and exit the lodge underwater without being spotted by predators.
The walls of the conical lodge are very strong due to layers of mud and sticks, and are extremely insulated. Even with subzero outside temperatures it will not drop below freezing inside the lodge due to retained body heat from the family of beavers. However, unlike most of their historic predators, beavers are excellent swimmers.
As a result beavers evolved to have a strong preference to remain in or very close to the safety of the water. The need for safety is the primary reason beavers build dams to create ponds. Beavers typically start building dams in low lying areas with shallow, moving water.
They will utilize natural or manmade objects such as a rock outcropping or a manmade stone wall, a constriction in the streambed, a tree stump, etc. So while somewhat predictable, they can select from a wide variety of spots in which to build a dam. Once a pond is formed beavers do not have to travel far on land to gain access to new trees.
The more area their dam floods, the more food they can safely access. Sometimes beavers will even excavate canals over a hundred feet long in order to bring water closer to stands of their favorite trees. This allows them to swim up close to the trees and retreat to the water quickly if they sense danger. In addition, they use the canal to float edible branches back to the pond.
Beavers predictably select sites to build their dams based primarily on topography and food supply. Preferred sites for damming will be in areas where the dam will flood a large flat area and there are plenty of desirable woody plants for food in the vicinity. Streams that are more than two feet deep or have strong currents are not generally dammed.
Beavers often situate their dams where there are constrictions in the stream flow natural or manmade. This is why beavers have a strong propensity to dam culverts. For relatively little work they can create a large dam and pond. Each beaver colony will usually establish one large pond which where they will build their lodge. In addition to this primary pond other smaller dams up and downstream are usually built to create smaller ponds. These smaller ponds permit safe travel for the beaver as it seeks out new food supplies.
The average beaver colony will dam a half-mile length of a small stream. Beavers are monogamous and mate for life. They do not breed until they are two to three years old.
In Massachusetts the female becomes pregnant during the winter and gives birth in May or June.. Beavers have one litter of 1 — 6 kits per year. The availability of food appears to affect the size of the litter. Only the adult female breeds. The average number of beavers in an established family is typically six or seven beavers. We have seen as few as one and as many as thirteen.
Once a beaver reaches the age of two they will usually leave the colony to find a mate and establish a colony of their own. This is the most very dangerous time in the life of a beaver. Not only can they be killed by predators or cars, other beavers will attack them if they enter their ponds. Beavers have been noted to travel ten or more miles searching for a place to live. Beavers have a highly organized social structure. Young beaver appear to play and wrestle with their siblings.
This helps to develop their motor skills. They will groom each other using their hands and teeth. Young beaver have innate abilities to build dams and lodges, but improve these skills watching their parents or older siblings. Beavers are typically social and peaceful animals, with a strong family structure. However, to protect their limited food supply, a beaver will not allow unrelated beavers to inhabit its pond.
To mark their territories they surround their ponds with scent mounds. They act as warnings to any beaver that may be passing through the area. Adult beavers will defend their territory by attacking any beaver outside its family who enters it. However, other than territorial disputes or self-defense, they appear to have a strong inhibition towards biting and are not known to attack humans unless provoked.

Over time, abandoned dams decay, and meadows appear. Beaver or muskrat? A small resurgence in beaver trapping has occurred in some areas where there is an over-population of beaver; trapping is done when the fur is of value, and the remainder of the animal may be used as feed. The beavers cover their lodges late each autumn with fresh mud, which freezes when frosts arrive. Dams prevent erosion and raise the water table, which helps purify the water as silt builds up and breaks down toxins, according to ADW. Johns Hopkins University Press.

Beaver | Forestry and Natural Resources
They are famous for building dams and lodges in aquatic areas. However, beavers eat a variety of plants and have ingenious ways to make sure there is food available all year long. How beavers eat and how they engineer their surroundings play a role in their importance to the environment.
Beavers are vegetarian animals that are known for felling trees for dam building and eating. Beavers prefer certain trees and other woody plants over others, but they also enjoy soft vegetation in the spring and summer.
Beavers are rodents. Beavers rank second only to the capybaras of South America in rodent size. They can be 3 to 4 feet in length and as tall as a foot and a half. A typical beaver weighs in the range of 40 to 60 pounds, and the largest recorded beaver weighed a startling pounds! Beavers can live up to 12 years in the wild. Beavers stand apart from other large aquatic rodents such as the muskrat and the nutria. Muskrats have long, flattened tails and are smaller than beavers. Nutria tails are roundish, and they tend to be in between a muskrat and beaver in size.
Beavers are generally brown, with very dark tails. Beavers can run on land, but that is not their greatest skill. They fare much better in water, where they can swim as fast as 6 miles per hour. And when they need to, they can stay under water for as many as 15 minutes. The beaver possesses a number of unique features that help it survive. Its stocky body helps to conserve heat, which helps it endure harsh winters and cold water.
Beavers have exceptional orange front teeth with a special coating. As in other rodents, these teeth grow continuously, and they are worn down by eating. The teeth in the back of their mouths are flat and white rather than orange. Those back teeth serve as grinders for the food the beaver chops with its front teeth. Beavers, in fact, eat with their mouths closed behind the first tooth. Since beaver teeth are excellent for gnawing at trees, the teeth are very sharp.
It's a good idea never to approach or provoke a beaver. They will charge and bite if they feel threatened, and that is one wicked bite! The iconic paddle-like tail of the beaver has no hair, but it does have dark scales. Tail shapes vary subtly depending on inheritance.
The beaver uses its tail to steer as it swims. And when a beaver is on land and needs to eat trees, these sturdy tails provide balance. Beavers also use their tails to slap the surface of water when they sense danger. These remarkable tails also serve as fat reserves to aid them through winter. Beavers must be able to find objects in dark water and other dim areas such as their lodges. Their eyes possess a special membrane that covers them while the animal is submerged.
While they do not have excellent vision, their whiskers aid them in detecting things. Beaver ears contain valves that shut when they go underwater, and they have good hearing.
Beavers have dexterous front feet that can hold objects, much as a person would, although they do not have opposable thumbs.
The rear feet of beavers are much larger and have webs between their toes that aid in their swimming. Their hind feet also possess a special toe called a preening toe that has a double toenail and allows beavers to comb and keep their fur in prime condition. Beavers walk on all five digits of their feet. If you have ever wished you had more hours in a day, you might envy beavers. While humans operate on a hour day length, generally nocturnal beavers do not.
They live primarily under water in low light in their lodges, which changes their natural circadian rhythms. Therefore the length of a beaver day tends to range from 26 to 29 hours. On their behinds, beavers boast castor and oil glands.
These produce scent for communication and territory marking, and oil to waterproof their fur, respectively. Beavers have interesting ways to communicate, such as the tail slap on the water for warning others.
The scent from their castor glands also allows beavers to communicate information when the animals rub the scent on mounds near their homes. The family groups that beavers form are stable, and older young help out with newborns alongside their parents until they are old enough to move on and breed.
Beavers are strict vegetarians. Beavers tend to build their homes alongside rivers and the edges of other bodies of water, within close proximity to trees. But beavers do not simply eat just any tree they come upon. The beaver diet includes certain varieties for eating, and others for building their dams and lodges. Also, the beaver diet depends on the season. In the spring and autumn, they will eat both woody and soft flora.
In the summer, most of the vegetation they eat will be soft. In winter, when there is little new growth on plants, beavers eat woody fare. Beavers have unique micro-organisms in their guts that help them digest as much as 30 percent of the cellulose they eat from plants. Trees that make up the beaver diet include bark from willow, cottonwood, aspen, poplar, maple, birch, oak, sycamore, ash, alder, black cherry and apple trees. Beavers will gnaw on trees until they fall, and then they clip branches from the resulting logs and add them to their food stash.
While beavers will sometimes eat fir, pine and other conifers, they do not favor them for food. They will often use such trees for dam building, however, or fell them to allow their favorite foods to grow instead.
You can spot areas of beaver lumbering where there are sharply pointed tree trunks, with grooves from their teeth marks, as well as piles of wood shaving around the trunks. Beavers can fell as many as trees in a year! Other woody plant items that beavers consume include roots, leaves, vines, new twigs, sedges, shrubs, grasses, blackberry canes, ferns and new bark. In addition to trees and woody plants, beaver food includes soft vegetation such as apples, grasses, water lilies, clover, giant ragweed, spatterdock, duck potatoes, cattails and watercress.
Occasionally beavers eat mushrooms as well. Beavers will even eat corn and beans. Beavers can store their food in a fascinating way for winter, when they are not able to access as many delicious plants. This amazing food stash is called a cache and tends to be made and used in colder climates. Beavers stay busy in the fall gathering food for their cold winter and upcoming times when food is less available. When beavers eat, they hold their food in their front legs much as people hold corn-on-the-cob, rotating the treats as they go.
Baby beavers are called kits, and they nurse from the milk of their mothers. Sometimes these kits even stand up to nurse.
After about six weeks, these kits will be old enough to eat solid beaver food, which every family member helps to bring them. Young beavers will stay with their families until they reach around two years old. Generally, beavers eat their food close to water and their lodges or dens. If the beaver food supply in an area becomes depleted, they will eventually move.
This may take several years to happen, though. For homeowners concerned about beavers intruding on their properties and eating their plants, fencing can be made to prevent this.
Also planting trees that beavers do not like eating, as a sort of natural fence, may be a good idea. Of course, beavers are most famous for their building dams. Beavers choose dam locations based on the sound of flowing water. They make watertight dams that drastically alter aquatic bodies such as rivers and streams and ponds. Beavers take sticks, reeds, saplings and branches, and they use mud as a caulking material to build their dams.
Beavers tend to build their dams in summer and fall, so be on the lookout for these impressive structures. The dams are not the homes of beavers; they build lodges to live in, give birth, raise young and store food.
These cleverly engineered lodges can be over 6 feet high and as wide as almost 40 feet! The lodge contains an entrance underwater that the beavers can access quickly, and climb through their passages to various rooms. Beavers even make a short of chimney or skylight when they build their lodges, to allow fresh air in. And beavers keep the floors of their rooms tidy with wood shavings.
While beavers are known for their dam and lodge building, when they're in areas that do not get very cold, or where there is level water like on a lake, they may not make either of these.
They instead will build dens in high banks, with underwater entrances. Beavers maintain and repair their lodges and dams constantly to keep them safe and sound for every season. With beavers being of a fairly large size, they are targets of larger predators, if any exist in their region. Some examples of beaver predators include cougars, wolves, bears, coyotes, bobcats, lynx, otters and mink.
Large birds of prey have been known to take juvenile beavers. Occasionally, dogs can also attack beavers.
