Where Do Beavers Live? Why Do They Have Unique Homes Like No 'Otters?

You must have heard of the phrase 'as busy as a beaver'.

This phrase is very accurate as these animals are considered nature's engineers! They work tirelessly during the summer and fall, using their fine woodworking skills to build dams and lodges.

Beavers are the largest rodents in North America and Europe and can be found living in large colonies near water bodies like lakes, ponds, rivers, and wetlands.

They use their sharp teeth to break off branches and sticks from trees, and then use them along with aquatic plants, leaves, and mud to build elaborate structures to live in.

Beaver dams are actually highly useful to the environment, as they naturally slow down the flow of fast-moving water bodies and help to create a slow-moving ecosystem, where many species can coexist and thrive alongside them.

What is the habitat and behavior of North American beavers?

North American beavers can be found all over the United States of America and Canada, except in the desert areas of Utah, Nevada, Arizona, and California. They are usually found in and around water bodies like ponds, lakes, rivers, streams, and wetlands.

Beavers are known for their habit of building dams. They use their strong front teeth to cut down branches and twigs from trees, using them to create strong barriers in the water which they then reinforce with reeds, twigs, leaves, and mud.

This slows down the flow of the river and creates a very slow-moving environment adjacent to it.

The slowing down of fast-moving streams and rivers like this helps to reduce soil erosion at the banks, as well as helps to create a blossoming ecosystem for many aquatic plants, river organisms, fish, and most importantly the beavers themselves.

This ecosystem also helps larger animals catch prey as well as provides them a safe area to drink water from.

Appearance-wise, the beavers that live in North America are round and stocky, with fur ranging from yellowish-brown to dark brown. It is almost black it is so dark.

They have flat, scaly tails and webbed hind feet which help them to move effortlessly in the water. Their front paws are separated into distinct fingers.

The purpose of their round bodies is to help them conserve heat, as they spend a lot of their time in the water, which can be quite cold at times. They are the largest rodent species in North America.

Their most remarkable feature is their long, bright orange incisors which they use to cut the wood into pieces and cleave sticks and twigs off trees for their dam-building purposes. These teeth never stop growing, but they are naturally worn down by a beaver's wood-cleaving activities.

In fact, beavers have to keep using them because if they become too long they can create a gap between the back molars, which will lead to food not being chewed probably which may result in starvation.

What is the habitat and behavior of Eurasian beavers?

Eurasian beavers refer to beavers living across the continent of Europe and Asia. Though once widespread, these beavers currently do not have as much reach as North American beavers do.

This decline has occurred due to the mass hunting of beavers for their fur and castoreum secretion sacs. However, efforts have been taken to reintroduce them, and they can now be found in the United Kingdom, Spain, Russia, China, Central Europe, and Mongolia.

The color of their fur ranges from light chestnut to deep brown and brownish-black even. They are the largest rodent species found in Europe and Asia, as the largest rodent, the Capybara, is only found in South America.

Though they may look similar to North American beavers with their rounder bodies and bright orange incisors, there are subtle differences with which you can tell the two apart. Eurasian beavers have 48 chromosomes, while North American beavers only have 40, making them incompatible to interbreed.

Eurasian beavers also have smaller, less rounded heads, along with longer and narrower muzzles. The North American beaver also has a square nasal opening, whereas those of Eurasian beavers are triangular.

The final noticeable difference is in the tails. The Eurasian beaver has a tail that is narrower and not as ovular in shape as that of the North American variety.

Similar to the North American variety, beavers live in and around ponds, lakes, wetlands, rivers, and streams and use their teeth to collect sticks and branches in order to build dams and slow down the water flows in their habitats.

What is a beaver den?

Beavers can also use their expert woodworking skills to build lodges, which are shaped like rounded domes. These can be quite complex and have multiple levels, both inside and above the water line.

They mostly spend their time in the upper levels, and you may find the floor covered in a layer of wood shavings and straw, which help absorb moisture from the surroundings and prevent the structure from collapsing, as well as act as bedding.

These lodges have underwater or underground entrances, which are built only after the upper layers are complete.

Beaver lodges have small windows at the top, which allow air to enter for circulation.

One lodge is usually used as a home by a single couple and their offspring. Many such small lodges create a colony where these social animals live, work, and eat together.

Beavers can be found most actively building dams and living structures during the summer and fall. They also collect food during this time, which they store in their dome-shaped houses. Young beavers start participating in building activities at around one years of age.

Where do beavers live in the wild?

Beavers do well in wet, thriving environments like near ponds, lakes, and rivers out in the wild. The area needs to have adequate tree cover and woodland areas, where beavers can find materials for their building dams.

Beaver teeth are very sharp and they can cleave branches from almost every type of tree, though their preferred types of wood to use are willow, aspen, poplar, birch, apple, and cherry. Once they create dams and bank lodges, the area transforms into a biodiversity-rich ecosystem, making beavers very important for the environment indeed!

Beaver lodges can be seen near dams, which have layers both inside as well as out of the water.

These are where beavers sleep when they are not tirelessly working, and where they store their food for the harsh winters. Both male and female beavers have scent glands called castors at the bases of their tails, which they use to mark their territory.

Beaver dam constructions have been seen to increase the concentration of many large animals like deer, bears, and foxes in the area as they receive a reliable source of water to drink from. The population of insects like dragonflies, snails, and mussels have also been observed to grow.

Where do beavers lives in captivity?

Beavers are kept in zoos for observation, however, they do not really do well in captivity as they have an inbuilt sense for building.

Being semi-aquatic animals, they are usually kept in enclosures with pools of water, as well as soft mud for digging.

Artificial lodges can be provided for them to live in, however, you may find them breaking apart these lodges and rebuilding them as they are used to doing this in the wild.

It is recommended to provide them with building materials like wood, branches, and plant material so that they can indulge in building activities, otherwise, they may become very bored and depressed.

They are also highly prone to escaping their enclosures, as they do not like confined space, and are more at home in the wild where they can build to their heart's content.

Conserving Beavers

Beavers are very important to the environment, as they are natures engineers. Their work helps to create small pockets of biodiversity in rivers and wetlands. Their work in slowing down the flow of rivers also helps to reduce soil erosion along the banks, as well as increase groundwater. This could prevent environmental problems in the long run.

Unfortunately, the Eurasian beaver population has greatly decreased over the years due to hunting them for their fur and castor sacs, which secrete castoreum, which is used as an artificial flavoring in many food products.

Regulations have been implemented to help increase the beaver population by preventing illegal hunting and coming up with alternatives to using their castor sacs and fur. Beaver traps can no longer be put in place, and building fences to keep beavers from straying too far from their habitats, keeping them inside protected areas.
