The South China tiger is a unique tiger species in China, with only 72 of them remaining, and the population quality is decreasing due to inbreeding. How to sustain this population has become an urgent problem to be solved. At the International Symposium on Rewilding of South China Tigers hosted by the State Forestry Administration in Beijing on the 18th, the preliminary planning plans of the two candidate rewilding experimental areas in Jiangxi and Hunan were reviewed by experts.

The State Forestry Administration said that it will promote the progress of the South China tiger rescue project and promote the reconstruction of domestic habitats, so as to provide conditions for the protection of the South China tiger population.

Questioning whether the wild South China tiger is really extinct?

At this seminar, foreign experts proposed that the South China tiger in the wild may be extinct in China, which has aroused doubts from many domestic experts.

According to Dr. Tilson, the last sighting of a South China tiger was in 1991. In the 18 months between 2000 and 2001, surveys were conducted in eight regions and five provinces in China where South China tigers had been found, and no trace of them was found, nor did interviews with local interviewees. They put the cattle in the mountains for 7 months and did not eat them.

According to the head of the Office of the Wildlife Research Center of the State Forestry Administration, it takes 50 years for a species to be declared extinct without an entity found, and now no entity has been found in the wild in nearly 20 years. But there are indications that it is difficult for South China tigers to form a stable population in the wild.

Breeding "inbreeding" is not as good as crossbreeding.

Previously, in order to let the South China tiger regain its wildness, China had let the South China tiger go abroad for field training, but one of them, ———Hope", unfortunately died, which once again caused domestic experts to think deeply about inbreeding. In their presentation, South African experts said that "Hope" had a smaller heart than its counterparts and had a lower immune system, so it died unexpectedly.

Xie Zhong, deputy secretary-general of the China Zoo Association, said that the South China tiger is bred from the wild before the 50s of the last century, with two major lineages in Shanghai and Guiyang, but any breeding is inbreeding, because there is no new provenance intervention, now the inbreeding coefficient is the highest, close to their own reproduction, resulting in a decrease in genetic diversity, reduced immunity, and it is difficult for cubs to survive in winter.

She proposes three solutions: finding tigers from the wild, but this is almost impossible at the moment; Cloning technology is used, but it is currently immature and unreliable; There is really no choice but to introduce subspecies of tigers of the same kind to preserve some of the genes.

Professor Xu Yanchun of the Wildlife Testing Center of the State Forestry Administration also suggested that other tiger species should be introduced to preserve genes through crossbreeding.

The way out is to rebuild the South China tiger habitat in the wild.

It is expected to be released to Liuyang and Zixi.

In order to allow the South China tiger to return to the wild and improve the quality of the population, China is planning to establish a wild release area. According to the army, in 2003 and 2004, experts were organized to visit Jiangxi, Fujian, Hunan, and other places on three occasions.

On the IUCN Red List of Threatened Species, the South China tiger (also known as the "Chinese tiger") is listed as critically endangered. There are currently fewer than 60 South China tigers in zoos in China, and the number of South China tigers in the wild is estimated to be no more than 30. South China tigers have not been found in the wild for nearly 20 years.

At present, there may be less than 25 South China tigers in the wild only in the mountainous areas of Guangdong, Hushengqiaonan, Jiangxi and Fujian, and only 15 in the wild.

As of September 2010, there were 98 South China tigers in 16 zoos (including breeding bases) across the country.

There are nine South China tigers in the wild in South Africa.

A total of 98 are known.

South China tigers are extinct in the wild, and there are almost 98 of them in captivity.

It is estimated that there are only 20-30 wild South China tigers in the world, and now there may not even be that number. Blind Jiji: But there are still 47 South China tigers living in 18 zoos in China.

Twelve years on, 40 years into the wild tiger, completely out of sight, probably gone. With a population of 1.4 billion, there are a lot of good achievements, but China's unique tiger can already be called a national treasure. Anyway, there are only 2,060 national treasure pandas, and 450 are bred in captivity.

However, only 70 tigers in China are bred in captivity and scattered throughout the country, and the wild is even extinct. Instead, India has conserved 4,500 Bengal-Indian tigers in the wild. Compared with the beginning of the conservation, it has increased by 4,000 heads, and countless more have been raised in captivity, and it has given land to the status of the Bengal-Indian tiger national beast.

What did we do? How to turn a blind eye!

In the early days of the founding of the People's Republic of China, there were about 4,000 South China tigers in China, but at that time, the habitat of South China tigers was shrinking day by day, and conflicts between humans and tigers occurred from time to time, so they were designated as pests at that time. Immediately, the South China tiger was hunted in large numbers, and various titles such as "tiger fighting expert" flew all over the sky. Today, there are fewer than 30 of the poor South China tigers left in the wild.

Although the hunting of tigers has been banned today, and various related measures have been introduced, it is difficult to reverse the tragic fate of the extinction of the South China tiger. This is not only the sorrow of the South China tiger, but also the sorrow of mankind.

According to reports, the South China tiger must reach at least 100 to maintain its population, but at present, there are only about 30 South China tigers in the wild, and only 51 in China's zoos (this number may not be enough). With the existing surviving population, this species can barely survive for twenty or thirty years at best.

I think there are less than 40 left, and there are very few .. anywayLet's protect .. moreIt is a national first-class protected animal ..At present, only China has ..

It seems to be extinct, and a few years ago it was said that there was a discovery, but it was confirmed that it was false. I'm still looking for details. For the time being, the state thinks that there is none.

In the zoo, two were just born this year. Here comes 70 integers, to say the wild one, how long has it been ten years since it was discovered.

47 in the zoo.

The wild ones may be extinct.

Guiyang News After nearly ten years of follow-up investigation, Ran Jingcheng, director of the Maolan National Nature Reserve Administration in Guizhou Province, initially found that there are only 30 to 50 wild South China tigers left in China.

The South China tiger is endemic to China and is listed as the most endangered tiger species in the world, and there are not as many South China tigers left in the world as the giant panda.

According to the research of relevant experts, Guizhou was once one of the areas with the highest concentration of tigers in South China. During the Qing Dynasty, there were at least 27 prefectures in Guizhou that had South China tigers. In recent years, in some areas of Guizhou, there have been frequent reports of South China tigers, but no one has seen them.

According to Liu Jiayan, director of the Nature Conservation Division of the Guizhou Provincial Environmental Protection Bureau, Guizhou has rich forest resources in history, and countless rare birds and animals are nurtured in the mountains and forests, which has a good ecological environment and is the embodiment of Guizhou's biodiversity. During the Yuan, Ming and Qing dynasties, Guizhou's population grew and development accelerated, but the forest coverage rate did not shrink much, and there were still tigers, leopards, bears and other animals in the forest.

According to previous surveys, there are only 20 to 30 South China tigers in the wild, and only 60 in Chinese zoos, which is even rarer than giant pandas. In a recent field expedition, not even live wild South China tigers were found, and the South China tiger is on the verge of extinction.

Last year's statistics showed that there are currently only 70 South China tigers in captivity in the world, distributed in 19 zoos in China (including five in Guangzhou Zoo), all of which are descendants of two males and four females of wild tigers. The wild South China tiger has so far only found feces and footprints, and is basically on the verge of extinction. The average life expectancy of South China tigers is 24 years old, and before the age of 16 is the breeding age, because some South China tigers cannot breed because of physical fitness and close relatives during the breeding age, the current national reproductive capacity is only 6-7 pairs.

Although the artificial breeding technology is developed at present, it is still difficult to carry out artificial sperm collection, mainly relying on natural reproduction, and the survival rate of newborn tiger cubs is low and the incidence rate is extremely high. From 1963 to 1995, 245 South China tiger symbiotic cubs were kept in captivity, but only 100 survived, with a survival rate of less than 41%.

The South China tiger is an endemic tiger subspecies in China, which was once distributed in a wide area of South China, East China, Southwest China, and Northwest China, and has a large population. In the past 40 years, the population of South China tigers has declined sharply due to shrinking natural distribution and human hunting, and at present, it is estimated that there are only about 30 South China tigers in the wild, and only 53 in captivity, which is less than the giant panda. It is one of the world's most endangered and rare animals.

Due to the very small number, the situation of inbreeding is quite serious, and the survival rate of its cubs is very low, less than 40%.

At present, there may be less than 25 South China tigers in the wild only in the mountainous areas on the border of Guangdong, Hunan, Jiangxi and Fujian, and a maximum of 15 in the wild.

As of September 2010, there were 98 South China tigers in 16 zoos (including breeding bases) across the country.

There are nine South China tigers in the wild in South Africa.

There are only 70 of them in the world, and the situation is even more dangerous than that of giant pandas.

The wild ones have not been found for many years, and the remaining ones are living in zoos or artificial breeding centers, and the number is optimistically estimated to be less than 100, and they are already on the verge of extinction.

The wild is very small and endangered. Most of the existing ones are bred in captivity.

The South China tiger has not been found in the wild for more than 20-30 years, and foreign scholars believe that it is extinct.

According to authoritative statistics from the China Zoo Association, as of December 31, 2008, there were only 80 South China tigers left in the country. (New numbers of South China tigers [births, deaths] between January and August 2009 have not yet been fully counted).

87 artificial. There are 7 new births this year (4 in Luoyang and 3 in Meihuashan), and these 7 have not yet been added to the genetic lineage. So 80 to be exact.

Among them, 9 were wild in South Africa, 4 large and 5 small; 12 in Suzhou; 11 in Meihua Mountain; 4 in Luoyang; 2 in Changsha, one large and one small; 3 in Fujian; 4 in Chongqing, two large and two small; 4 in Nanchang, two large and two small; 2 in Shenzhen; 2 in Shaoguan; 17 in Shanghai; 6 in Guangzhou and 4 in Guiyang.
