Physical Characteristics

Both the Eurasian beaver and the North American beaver are large rodents known for their distinctive flat tails and webbed hind feet. However, there are some differences in size between the two species. The Eurasian beaver, also known as the European beaver, is typically larger than its North American counterpart. Adult Eurasian beavers can weigh between 11 to 30 kg (24 to 66 lbs) and measure around 100 to 130 cm (39 to 51 inches) in length, including the tail. In comparison, North American beavers are slightly smaller, with adults weighing between 11 to 32 kg (24 to 71 lbs) and measuring around 74 to 90 cm (29 to 35 inches) in length.

Habitat and Distribution

Eurasian beavers are native to Europe and Asia, with populations found in countries such as Russia, Germany, and France. They prefer to inhabit freshwater habitats such as rivers, streams, and lakes. In contrast, North American beavers are native to North America and can be found throughout Canada and the United States. They also prefer freshwater habitats but are more adaptable and can be found in a variety of environments, including ponds, marshes, and even urban areas.

Behavior and Diet

Both Eurasian and North American beavers are known for their impressive engineering skills, building dams and lodges using branches, mud, and rocks. These structures help create suitable habitats for the beavers and provide protection from predators. In terms of diet, both species are herbivores and primarily feed on tree bark, leaves, and aquatic plants. However, North American beavers tend to have a more varied diet compared to Eurasian beavers, consuming a wider range of plant species.

Reproduction and Lifespan

Reproduction in Eurasian and North American beavers is similar, with females giving birth to 1 to 6 kits after a gestation period of around 100 days. The kits are born fully furred and with their eyes open, ready to start exploring their surroundings. Both species have a similar lifespan in the wild, with individuals typically living for around 10 to 15 years. However, beavers in captivity can live much longer, with some reaching up to 20 years of age.

Conservation Status

Both Eurasian and North American beavers have faced threats to their populations in the past due to hunting and habitat loss. However, conservation efforts have helped to increase their numbers in recent years. The Eurasian beaver is currently listed as Least Concern on the IUCN Red List, thanks to successful reintroduction programs in several European countries. In comparison, the North American beaver is also considered of Least Concern, with stable populations across its range.
