The fur of the beaver may be light rust, brown or black and it has often been highly sought after by humans. Castoreum is a type of secretion released by the scent glands of the Eurasian beaver. As the castoreum is considered to have medicinal properties it has led to increased hunting of it.
They are herbivores and their diet consists of various plants while they are considered to favour leaves, bark, twigs, roots, and aquatic plants. Their strong large teeth are known to cut away or bite or grind away at trees.
Humans are the best at being able to manipulate and alter their environment. Of all the animals, the beaver is the best at being able to do just that as well.
A baby Eurasian beaver is called a kit, kitten or pup. A group of Eurasian beavers are referred to as family or colony. The adult Eurasian beaver weighs about 18kgs.
The beaver population in Sweden is increasing. Sweden has introduced the beaver back into Sweden, after its extinction in the late 19th century (late 1800s). It was mass onset of agriculture, deforestation and grazing with the constant strong hunting that lead to all beavers being at extreme threat of extinction in Europe. From 1922 to 1939, 80 beavers from Finland were transported and released into central Sweden. From that time the beaver population has thrived. Currently guided tours are available to view this creature. Often the best sites of beavers are while you are on a boat, floating along a river or lake.
