The living environment and existing number of Chinese alligators, endangerment level, and endangerme

Living environment: Dig holes and inhabit rivers and lakes and ponds.

Endangered factors: habitat destruction and poaching.

Number in existence: less than 200.

Endangered status: first-class protected animals.

AlligatorIt is a first-class protected animal.

The Chinese alligator or tuó is a crocodile endemic to China and one of the smallest crocodile species in the world. Because it lives in the Yangtze River Basin, it is called "Yangtze Alligator".

In the Chinese alligator, early dinosaurs can still be found to this day.

Many characteristics of reptiles. Therefore, people call the Chinese alligator a "living fossil". In 1972, China listed it as a national first-class protected rare animal, and it has now been included in China's "List of National Key Protected Wild Animals".

Protective measures:

In 1982, in order to save all the animals endemic to China and protected by the national first-class.

Anhui Province approved the establishment of Anhui Yangtze Alligator Provincial Reserve and Yangtze Alligator Breeding Research Center, which was upgraded to a national nature reserve in 1986. The area of the reserve is 18,565 hectares, involving five counties (districts) of Xuanzhou, Langxi, Jingxian, Guangde and Nanling of Wuhu City.

Summary. Hello, the endangered status of the Chinese alligator is as follows, 1 habitat, decreasing. 2. The wild population is small and there is little food. 3. Human activities are frequent and pollution is serious.

Hello, the endangered status of the Chinese alligator is as follows: 1. Habitat, and the reduction is quiet. 2. The number of positive keys in the wild population is small, and the food is rarely transported. 3. Human activities are frequent and pollution is serious.

These are some of the main phenomena that are endangered in the Chinese alligator. <>Therefore, it is very important for people to protect the natural environment from being destroyed and cherish the current living environment.

Hello, as ordinary citizens, we must take care of the environment. Caring for wildlife.

AlligatorIt is mainly found in lakes, ponds and swamps in the lower reaches of the Yangtze River in China.

The Chinese alligator is a crocodile of the genus Alligator in the family Alligatoridae. It is a crocodile endemic to China and is one of the smallest crocodile species in the world. It is both ancient and a very rare reptile in the world.

Because it lives in the Yangtze River basin.

Therefore, it is called "Chinese alligator". Alligators prefer to inhabit lakes, swampy flats, or hilly mountain streams in humid areas overgrown with grass.

The Chinese alligator is a specialty of the Yangtze River Basin. Chinese alligators live in fresh water, mainly distributed in local areas of Anhui, Zhejiang, Jiangxi and other places in China. It is both ancient and now a very scarce reptile that is on the verge of extinction in the world.

In the 19th century, the Yangtze crocodile infested the lower reaches of the Yangtze River, Hubei, Anhui, Jiangxi and Jiangsu, and preferred to dig holes in the shallows of hills, ravines and lakes, but this reptile could not do without water. It is clumsy and slow on land, but once in the water, it is like a fish in water. And this amphibious characteristic has led to the tragic fate of the Chinese alligator.

The shallows where the Chinese alligator burrows are mostly reclaimed as farmland, the hilly vegetation has been greatly destroyed, the water storage capacity of the hilly area has been greatly reduced, and drought and waterlogging have occurred frequently, so that the Chinese alligator has to leave its burrow and look for suitable habitat everywhere. This migration process in turn creates opportunities for natural death and human hunting. Alligators have been hunted in large numbers over the years, burrows have been vandalized, and eggs have been smashed or taken away.

The use of chemical fertilizers and pesticides has also greatly reduced the number of aquatic animals, which are the main food of the Chinese alligator. At present, the distribution range of Chinese alligators has been reduced to a narrow area at the junction of Jiangxi, Anhui and Zhejiang provinces.

About 10,000 heads, mostly in Anhui, are not extinct.

Xuancheng, Anhui Province has built the world's only Yangtze alligator reserve - Xuancheng Yangtze Alligator National Nature Reserve.

There may be fewer than 200 Chinese alligators in the wild, of which about 40 are adults.

Wild Chinese alligators are native to the vast areas of the middle and lower reaches of the Yangtze River, and due to their dense population and rapid development in the past 100 years, their habitats have been continuously developed into agricultural land such as arable land, fish ponds, etc. The living space of the Chinese alligator was continuously compressed, until the number of wild Chinese alligators dropped to less than 300 in the seventies of the last century, and the living environment was also compressed to the narrow area at the junction of Jiangsu, Anhui and Zhejiang. Chinese alligators have a docile temperament and generally do not take the initiative to attack people.

As with other animals, they tend to be aggressive when they are short-tempered during the breeding season, but this aggression usually does not cause substantial harm to humans.

The living environment of wild Chinese alligators is greatly affected by human factors, especially during the breeding period, and human activities directly affect the egg production of Chinese alligators. Human activities have led to the continuous change of their laying grounds, and the destruction of their nests by humans has also directly led to a decrease in hatching rates. Due to the fact that the habitat of the alligator is gradually turned into a farmland fish pond, it is easy for farmers to catch the alligator by mistake in the process of fishing, and the failure to release it in time or not get scientific breeding will also lead to the death of the alligator. The use of pesticides indirectly threatens the survival of Chinese alligators, and wild Chinese alligators often die by eating poisoned prey. The activities of the Chinese alligator have caused damage to agricultural production and led to the killing of the alligator.

The private trade of Chinese alligators poses a great threat to the survival of wild Chinese alligators, and the catering industry often causes poaching of wild Chinese alligators. This kind of poaching is not difficult in the habitat of the alligator with high population density, many wild alligators live around farmland or fish ponds, and the docile timidity of the alligator also brings an opportunity for poachers to hunt the alligator with the help of some simple fishing tools. This is one of the reasons why the number of wild alligators has been hovering between 200 and 300.

Although designated as a crocodile sanctuary by the Anhui Provincial Forestry Department, local villagers still use the ponds to irrigate farmland, raise cattle, fish and ducks.

Of the 13 designated sites, only 10 have reported alligator sightings. The total number of crocodiles in these areas is estimated to be about 60. Large populations can consist of 10-11 individuals, with a maximum of one female.

Only two designated sites show signs of alligator breeding, and crocodile eggs are usually collected at the Anhui Crocodile Breeding Center for incubation.

In addition to the designated spots, there are also Chinese alligators in a few other areas. But the situation in these areas is often worse than at the designated points.

It is estimated that there are only 130-150 alligators in the wild today, and they are declining at a rate of 4-6% per year.

Chinese alligators live in aquatic ecosystems.

The alligator likes to be quiet, often secluded in caves during the day and goes out to forage for food at night. However, it also sometimes comes out during the day, especially prefers to bask on the shore near the cave and on the beach. It often closes its eyes tightly and crawls motionless in a semi-sleepy state, giving people the illusion of sluggishness.

However, when it encounters predators or finds food, it will immediately flick its thick tail from side to side, and quickly sink to the bottom to avoid predators or pursue food.

The alligator eats a lot of food, can store a large amount of absorbed nutrients in the body, because it has a strong hunger resistance, can survive a long hibernation period, so the alligator can not eat for a long time.

Chinese alligators live in aquatic ecosystems. Aquatic ecosystems are the general term for various types of water ecosystems on the earth's surface. Aquatic ecosystems are inhabited by communities of autotrophs (algae, aquatic weeds, etc.), heterotrophs (various invertebrates and vertebrates), and decomposer organisms (various microorganisms).

Various biological communities and their interactions with the water environment maintain specific material cycles and energy flows, constituting a complete ecological unit.
