Due to habitat destruction and poaching. By the beginning of 20 15, there were only 500 wild Siberian tigers in the world. In the history of our country, Siberian tigers are widely distributed in northeast forest areas. However, with the continuous expansion of human activities, especially the increasingly serious deforestation, the habitat of the Siberian tiger is becoming less and less. What about those who have lost their homes? King of the forest? On the verge of extinction. Animals are natural and ecological? Balancer? . Protecting wild tigers means protecting the health of the whole ecosystem, that is, protecting ecological homes that can provide us with food, fuel, fiber and medicine. Therefore, we have an obligation to protect all endangered species, including tigers.

Ethnological History The Northeast Tiger is one of the largest cats in the world. It originated in Northeast Asia and once spread all over Siberia, Russia and South Korea, with a history of 3 million years. Also known as the Northeast Tiger in China. Despite its huge size and amazing strength, the wild Siberian tiger is still on the verge of extinction, and there is only a thin line between the survival of this rare species. Genetic studies show that the Northeast Tiger and the extinct Li Haihu have the closest genetic relationship with other tiger subspecies. According to the investigation, the common ancestor of these two tigers may have settled and multiplied in Central Asia and the Caspian Sea through the ancient Silk Road in China about 10,000 years ago.

Another reason is that the economic value of the Siberian tiger is extremely high, and its meat and viscera can be used as medicine to treat various chronic diseases. The value of an adult tiger is equivalent to more than 30 minks, which is also the reason why the Northeast Tiger was ruthlessly hunted. The reproductive rate of tigers is also low, and their life span is about 25 years. Sexually mature at the age of three or four, from 65438+February to February of the following year. The gestation period is about 105 ~ 1 10 days. Generally, each child has three or four cubs. The cubs grew up sucking their mother's milk. They have to follow the tiger mother for a year or two before they can live independently.

Think about it, the killing rate of the Siberian tiger greatly exceeds its reproductive rate, which is the direct reason why the Siberian tiger is on the verge of extinction. Deforestation, indiscriminate catching and killing of wild animals, and serious damage to the ecological balance are another important indirect reason for the extinction of the Northeast Tiger. As we all know, the forest is the living environment of tigers. In recent years, due to the large number of poachers, the carnivore tiger has been greatly reduced. Therefore, it is very important to keep the ecological balance between ungulates such as wild boar and deer and tigers. According to the investigation, there should be no less than 150 ~ 160 wild boar and no less than 180 ~ 190 deer in the territory of a Siberian tiger. As long as the tiger is full, it will not take the initiative to attack people and animals. The living area has decreased, and the food sources have also decreased. Can the Northeast Tiger not be endangered?
