In 26 years, no one has seen a wild South China tiger, and what is the probability that they are sti

Wild South China tigers still exist in the wild, but out of fear of humans, they are far away from humans, and they don't even dare to bark for self-protection, and they are well and deeply hidden. In some sparsely populated mountainous areas with good natural ecosystems, and not designated as nature reserves, wild South China tigers are likely to exist.

With such a large number of South China, Central China, and East China, I personally think that there should still be a small amount of existence, and the country should increase its efforts to protect it! With today's technological and economic conditions, the South China tiger should not and cannot be allowed to become extinct!

The probability of survival is relatively small, about 30 percent, because the natural environment has been severely damaged and their food has been reduced.

100% of South China tigers in the wild are gone, the key is that there is no suitable habitat, even if there are a few habitats for survival, but the area is too small, and there is no suitable prey population.

I think there is a 40% chance of surviving in the wild, and in most cases it is not possible.

The report said that wild boars in the south were chaotic, and they could starve to death if they were released into the wild? After the release, as long as there are people who live, it will be good slowly.

The probability of a wild South China tiger surviving in the wild is almost zero.

Everything I saw was eaten by the tiger. 丨.

Unless wild boars will give birth to South China tigers.

Zhenglong has seen it, and there are few.

Baishanzu's Investigation Team: Are you blind to us?

Just ask Zhenglong next week!

Very small. Because human sightings are all over southern China, but no one has found the South China tiger in the wild, the probability that they are still alive in the wild is very small.

Yes. South China Tiger.

It lives mainly in the tropical rainforests of southern China.

Evergreen broad-leaved forests are also often found in mountain deciduous broad-leaved forests and coniferous and broad-leaved mixed forests such as ridges, dwarf forest shrubs and rocky or gravel ponds.

Although the South China tiger does not like to swim long distances, it can swim through narrow straits, so it can also be found on islands such as Xiamen. Mostly live alone, do not form groups, are mostly active at night, have a developed sense of smell, are agile, good at swimming, but not good at climbing trees. Similar to other tiger subspecies.

Is China's wild South China tiger extinct?

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.

The South China tiger was transported to Africa for rewilding, and in a foreign country, the baby South China tiger was born.

It takes 50 years for a species to be declared extinct without an entity found, and now it has been nearly 20 years that no entity has been found in the wild. But there are indications that it is difficult for South China tigers to form a stable population in the wild.

In the past 20 years, it has been difficult to find wild South China tigers In the past 20 years, people have constantly asked: how many wild South China tigers are there in China? A few days ago, at the "International Symposium on the Rewilding of South China Tigers" held in Beijing, the Minnesota Zoo expert Tierson pointed out that before 1990, China had never found the South China tiger in the wild, and it can be said that the South China tiger has no wild individuals.

In 2000, the State Forestry Administration organized internationally renowned tiger experts, American biologist Tierson and other experts to conduct an 18-month survey of the wild population and habitat of South China tigers. Thierson submitted a report concluding that "no evidence has been found that the South China tiger is still alive in the wild". According to the International Convention on Endangered Wild Fauna and Flora, if no animal is found in the wild for 50 consecutive years, the species is declared extinct.

At present, the South China tiger is the world's most endangered species. Although there is still some time to go before 50 years, the only way to prevent the extinction of their endangered genes is to hope for the South China tigers in captivity in zoos. There are only 72 South China tigers left in China "As of November 2005, there were only 72 South China tigers alive in China.

Xie Zhong, deputy secretary general of the China Zoo Association, said that three of them were being rewilded in South Africa. In fact, there are only 69 South China tigers in captivity in zoos in China, and they are scattered in zoos across the country. The inbreeding of South China tigers has led to the decline of the quality of South China tiger cubs to a certain extent.

This is the conclusion of Xie Zhong and others after analysis. She said that all the South China tigers in China's zoos are descendants of six South China tigers. Of these, five tigers were captured in Guizhou Province in 1958 and 1962, and the other one was captured in Fujian Province in 1970.

Check the pedigree of the existing South China tiger, not only from the "same generation" marriage between brothers and sisters, but also from the "generational" mating between father and daughter, grandparents and grandchildren! Inbreeding has led to a rapid decline in the genetic diversity of South China tigers. Wildlife expert Army said that due to the limited number in the zoo, the South China tigers used for mating are becoming closer and closer to each other, and the genetic diversity is gradually decreasing, which also leads to a natural lack of certain immunity.

At present, some newly-born tiger cubs have begun to show a short tail (a short tail). There is no doubt that if this trend is allowed to continue, the world's most endangered animal will cease to exist in the near future.

In the reckless mountains at the junction of Hunan and Jiangxi, there may be a few wild South China tigers that have survived in the depths of the inaccessible deep mountains and old forests, but even if there is, it has no effect on the recovery of the entire South China tiger population, and now the remaining captive South China tigers are genetically degraded quite seriously, they are all inbred, and the South China tigers have no hope of returning to the deep forests, from this point of view, the extinction of the South China tigers is a foregone conclusion!

There are no more wild ones, alas! Thank you for the adoption.
