The North American beaver (Castor canadensis) is the largest rodent in the world and it resides in habitats near rivers, lakes, and ponds in North America. They are known to build beaver dams and lodges by collecting materials and digging pathways for small streams. The American beaver eats plants, leaves, tree bark, and fruits as food. Since they are so adept at swimming due to their webbed feet, they can also be called water beavers and eat aquatic plants for food as well. These beavers are also known to slap their broad flat tails on the surface of the water to signal danger.

American beavers are described as a keystone species because of their contribution to altering nature through beaver dams and creating habitats for other flora and fauna. This beavers species is largely native to North America and is not commonly found outside of it. These beavers live for about 10 to 20 years and female beavers have a gestation period of three months. They give birth to one to four babies each breeding season. After growing up in their parent's lodge, young beavers eventually obtain maturity and become independent. They have webbed feet, which makes swimming an easy task and these North American beavers are popular in the beaver fur trade industry and often overhunted.

American beavers are mammals of North America (they are found in most regions in North America, with the exception of desert regions) but they are also found in some parts of Canada and Mexico. They are also present in parts of Europe and Asia. Their habitat includes temperate forests, grasslands, lakes, and wetlands where food is readily available.

What is an American beaver's habitat?

The American beaver (Castor canadensis) lives near habitats that range from lakes ponds to rivers. Beavers build their lodgings on islands, river shores, and the banks of ponds. This lodge is made up of twigs, moss, or grass woven together to make a dome shape and plastered with mud. The dome may be up to 94 in (240 cm) in size. They prefer living near water bodies due to this beaver's inherent tendencies to build dams.

Who do American beavers live with?

American beavers are a highly social species and do not live alone. They live with other beavers in colonies. Usually, one dome or lodging will be home to a monogamous couple and their babies. They tend to be very territorial and protect their homes from other beaver colonies.

How long does an American beaver live?

The average American beaver lives to about 10-20 years of age.

How do they reproduce?

Beavers are monogamous, so they pick a partner and spend their lives with this single beaver. Only after their partner dies are they known to seek the company of another beaver. Their breeding season lasts from January to March and November to December in the south. The gestation period of a female is three months long and about three to six babies can be born in one litter. Female beavers only have kits once every year and the male beaver is known to collect food for the pregnant female beaver. Young beavers can leave their parents' lodges after two years and they gain sexual maturity in three years.

What is their conservation status?

The conservation status of American beavers is Least Concern, which means that their population is relatively stable. In the past, this species has come near to extinction in their original habitats, but luckily, their population has seen a massive improvement in the past century. Beavers are still not completely safe though and often fall prey to hunters because of their fur. Pollution and loss of habitat are also other reasons why the beaver population might be dropping.
