In summer, beavers also feed on herbaceous plants such as calamus, vitex, shallots and grasses. Due to feeding, fixed roads are often trodden on the shore.

In autumn, beavers are active in the morning and dusk, biting off branches and other trees by about 1 m, and carrying them to the deep water near the entrance of the cave for storage, so as to be eaten during the winter. In the area where beavers live, it is common to see stumps with thick bowl mouths, which is the masterpiece of beavers.

Beaver, scientific name"Beaver"。It is the largest of the Chinese rodents. It is produced in the Altay region of northern Xinjiang, and is distributed in the Ulungu River, Qingger River, Burgen River, Chagangol River and other places in China.

It belongs to the national first-class protected animals. Beavers are fat and strong, with short, pure heads, small eyes, small ears, and short necks. The front teeth are sharp, and the muscles are particularly developed.

It inhabits the riverside of the cold temperate coniferous forest and the forest edge of the mixed coniferous and broad-leaved villages, and lives in caves. It is mainly nocturnal and feeds on fresh bark, twigs and reeds. Beavers were widely distributed 2 million years ago, so they are also known as living fossils of ancient vertebrates, and have high research value.

It is one of the oldest animals in the world, known as the "architect" of the animal world and the "living fossil" of ancient vertebrates, and the "Regulations of the People's Republic of China on the Protection and Management of Wildlife Resources" (draft) lists the beaver as the first category of protected animals.

Behavioral habits: nocturnal activity, rarely out of the hole during the day, good swimming and diving, no hibernation. One of the beavers' unique skills is the dam, and wherever the beavers live or have lived, there is a pond, lake or swamp.

Beavers have always worked tirelessly to build dikes with branches, rocks and soft mud to block the path of streams, which can merge into ponds and lakes of several hectares. Beavers have the ability to modify their habitat. When entering a new habitat or when the water level of the habitat drops, the beaver will build a dam with branches, mud, etc., to store water to protect the hole from being infestation from natural predators.

Beavers sometimes dig up 100 meters of canals in order to transport the building materials used for dam construction on the shore to the dams. Beavers move slowly and clumsily, not far from the water's edge. It is weak in self-defense, timid, prefers quiet environments, jumps into the water at the first moment of fright and danger, and slaps the surface of the water with its tail to warn its kind.
