Family of Castoridae contains two species, Castor canadensis (the true beaver or common) and Castor fiber (European or Eurasian beaver). In the past Eurasian beaver lived in the area from Eastern Siberia to British Isles. Near the conclusion of the 19th century, beaver population decreased to about 1,200 because of the over hunting.
On the other hand, thanks to the protection, reintroduction and natural spread in the twentieth century, their number has increased to approximately 593,000 on 2002. In our times, you can find them across Europe, with the exception of Italy, Iberia and the southern Balkans. You can find them in Mongolia as well, Khabarovsk and China.
The common beaver or true beaver or beaver, that is C. Canadian, were found in North America first. The true beaver are living , apart from Nevada, Southern California, parts of Alaska and most of Florida,. There were few reports of inaccessible populations in places such as Temecula Creek and Southern California also.
Since 1975 Canadensis is Canada's official symbol. Since 1853 till 1877 3 million beavers have been harvested with the intention to sell in UK by Hudson Bay Company. Furs were so precious that it contributed significantly to the westward settlement and development of human settlement of Canada and North America.
These animals are known for their normal trait of building dams on streams and rivers, and building houses, on the pond. Beavers as well build canals, which are very difficult to drag on the ground. They utilize their sharp teeth to cut plants and trees that they use for construction and food. Initially, they put vertical poles and then they fill the gaps of the poles with horizontally crisscrossed placed branches. Beavers seal the gaps of the branches by blending mud and weeds until the dam confiscate adequate water to encircle the lodge.
Beavers are also known for their alarm signal: while frightened or starthtened, a beaver will quickly dive while vehemently spanking the water with its wide tail, and these spanks can be heard from great distances above and below water. It warns other beavers in the region. Once one of them sounds the alarm, beavers in the nearest areas dive and probably will not resurface for some time. These animals are sluggish on land, but they are perfect swimmers and can stay under water for almost 15 minutes.
