What is Canada's National Animal
The Canadian beaver or American beaver (Castor canadensis) belongs to the genus beaver (Castor) from the order of the rodents (Rodentia). He is close with the European beaver (Castor fiber) and some zoologists consider both to be subspecies of only one species. However, it is usually larger and has 40 chromosomes, while the European beaver has 48.
The Canadian beaver is the national animal of Canada and is depicted on the Canadian five cent coin. However, it is considered a pest in some parts of Canada.

The Canadian beaver was native to all of Canada except the northernmost areas, all of the United States except Nevada, most of Florida, northern California, and some adjacent arid areas. In addition, it was found in a narrow strip in northern Mexico, where it is now as good as extinct. It has also been eradicated in some parts of the United States, such as large parts of Delaware, eastern Massachusetts or the western half of Ohio. In a total of 15 out of 49 states in the USA in which it originally appeared, there were no more beavers, mainly due to excessive hunting. Today it is represented again, at least in smaller populations, through natural expansion and reintroduction in all states in which it originally occurred. The IUCN therefore classifies it as safe.
When Canadian beavers settled in Tierra del Fuego in 1946 with the aim of using fur animals, the beaver spread rapidly in this area due to the lack of predators.
In addition, the Canadian beaver is now found in Europe in parts of Finland and in Kamchatka through resettlement.
Way of life
The Canadian beaver's way of life hardly differs from that of the European beaver. You can also cut trees to build larger beaver dams.
Beaver and human
During the time of the settlement by the Europeans, beaver hair (castor hats) and beaver fur quickly became a sought-after commodity. At the height of the beaver fur trade, around 200,000 beaver pelts were exported to Europe each year. Around 1900, the trade in beaver furs fell sharply, not only because beavers went out of fashion, but because there were fewer and fewer animals in all of North America. Beaver populations ceased to exist in many areas of North America in the first half of the 20th century.
Only around 1930 did a rethink in Canada slowly begin. Beaver hunting was banned for many years and the populations recovered. Beavers have even been reintroduced in regions of Canada where they were eradicated, so that today there is a healthy beaver population that is also hunted almost everywhere in Canada.
In large parts of Canada, there are few conflicts with humans due to the sparse population. But where it becomes a nuisance to people through the felling and gnawing of trees as well as dam building, one does not shy away from fighting.
In Germany, Canadian beavers may not be bred, offered, sold, given or kept in stock for sale by private individuals.
