Judging from the past lives of the Northeast Tiger, can it still spread all over the snowy forest?

Northeast Tiger is a tiger with the largest number of wild animals in China, but it is only short and tall, even if the number is more than 30. Fortunately, due to proper protection measures, it shows an increasing trend every year, although the growth rate is a bit slow, about one per year. This is no wonder, after all, the base is small, and the tiger's reproductive ability is not strong. The life span of wild Amur tiger is 15- 17, and sexual maturity begins at the age of 2. Most of the children born in one birth are concentrated in two births, and they can't regenerate until the cubs are mature, so there are only a handful of offspring that the mother tiger can give birth to in her life.

Of course, this is only a theoretical result. In fact, due to competition, natural environment and other factors, the mortality rate is also included, so it is understandable that tigers grow slowly. The Siberian tiger is called Siberian tiger in the world. In fact, this name is not so accurate, and it can even be said to be extremely misleading. As we all know, Siberia refers to most areas from the Ural Mountains in the west to the Cape of Gerzhnev in the east. It can be simply understood that Russia's region in Asia is quite vast.

The distribution of Siberian tigers is only in the southeast corner of Siberia, which is only about 6.5438+0.6 million square kilometers, which is similar to that of Jilin Province, while the whole Siberia has 6.5438+0.32 million square kilometers. It can be said that the distribution of the Northeast Tiger here is not even a fraction, so the name Northeast Tiger always feels less appropriate. In Russian, the Amur tiger is also called Amur tiger, which means Amur tiger. This title is more appropriate.

The Siberian tiger is very famous in the world. Today, we will talk about this tiger's past life. At present, we all know that the South China Tiger is a unique tiger in China. In fact, before 1858, the Northeast Tiger was also a unique tiger in China, but in this year, the Qing Dynasty ceded a large area of land in Amur to Russia, and the Northeast Tiger became a kind of tiger in China and Russia. The distribution of the Siberian tiger has changed several times in history, and its fate can be said to be quite bumpy.

At the end of 19, the number of Siberian tigers in China was still considerable, about1400-2,400, while Russia only had about 800. After entering the 20th century, the number of Siberian tigers in Russia decreased sharply due to the killing of Siberian tigers, deforestation and the construction of railways. Of course, in addition to being destroyed, a considerable number of them fled to the northeast. After 1930s, there were only more than 40 optimistic estimates. Later, Russia realized the importance of tigers to the environment and biodiversity and began to protect the Northeast Tiger.

In the 1950s, China seems to have followed the old Russian way in dealing with the Northeast Tiger, cutting down a lot of forests and killing tiger food, such as wild boar, red deer and roe deer. The number of Siberian tigers in China has dropped sharply. Like Russia before, some of them chose to flee abroad. Immigrants? Instantly expanded the number of wild Siberian tigers in Russia. By the beginning of 2 1 century, the number of Siberian tigers in Russia had recovered to about 500.

As mentioned above, the importance of tigers to the environment and biodiversity is self-evident. In 1980s, China also realized the value of the Northeast Tiger and began to protect it vigorously. The establishment of Qinghai Sanjiangyuan National Park is the best proof. Because China has been committed to protecting the Northeast Tiger for many years, it has also attracted the favor of Russian wild tigers in restoring their numbers. Immigrants? The descendants of the Northeast Tiger are moving back.

In June 5438+this year 10, the Northeast Tiger and Leopard National Park Administration photographed a wild female Siberian tiger, and her three children were coming from Russia to settle in the northeast of China. This is a great event. The importance of the arrival of the mother tiger is self-evident, and it is also the best reward for protecting the living environment of the Northeast Tiger in China. Before the Qing Dynasty, there were Siberian tigers in most forest areas in China, but later, due to human factors, the tigers here disappeared. Nowadays, China has made a lot of efforts to attract wild Siberian tigers to settle here.

Among them, a batch of sika deer and red deer released in 20 14 have been well bred, and the establishment of Northeast Tiger and Leopard Park means that the time to attract Russian Siberian tigers is slowly maturing. As long as this ecological channel between China and Russia is opened, there will be a steady stream of Siberian tigers going to the northeast of China in the next few years, because compared with the cold and snowy Siberian inland, the Linhai Snowfield in the northeast is more suitable for their growth. I believe it will be soon.
