For most wild animals, forests can be said to be their refuges, providing them with a habitat on the one hand, and an adequate food source on the other. Although the forests of many countries and regions are decreasing, our country has been promoting afforestation over the years, so the forest area of our country has increased year by year, and the land of our country is greener than ever. According to the data released by the Ministry of Ecology and Environment, in 2019, our national forest area reached 220 million hectares, the forest coverage rate reached 22.96%, and the grassland area also reached nearly 400 million hectares. With the increase of the area of forests and grasslands, our environment has slowly become better, and the number of wild animals living in these grasslands and forests will increase, and some animals that have disappeared for many years will even reappear in front of us.
< h1 class= "pgc-h-arrow-right" disappeared > 30 years, and the little civet cat reappeared in Zhejiang! </h1>
In Wuyanling National Nature Reserve, the little civet cat, a national second-level protected animal, appeared in the picture of the infrared camera. In nature reserves, it is not unusual to see wild animals, because these reserves themselves live a large number of wild animals, but the small civet cats that have appeared now have disappeared in the Zhejiang region for more than 30 years. After more than 30 years, they are back and filmed.
Many friends may not be very familiar with the little spirit cat, and the common name of the little spirit cat is still more, such as the seven beavers, black-footed cats, arrow cats, pen cats, spotted spirit cats, incense cats, etc., belonging to the spirit cat family, the small spirit cat genus. The average civet cat can grow to 58 cm in length, which is nearly half a meter in length, and the length of its tail can reach about 40 cm, but its weight is relatively light, only 2-4 kg. These kittens generally rest during the day, come out at night or in the morning, and feed on rats, insects, frogs, birds, and animals, as well as fruit.
Why do species that have disappeared for many years > < h1 class="pgc-h-arrow-right" reappear? </h1>
Judging whether a species has disappeared or become extinct is actually subjective to a certain extent. Because these wild animals themselves live in the wild, especially in some remote areas, sparsely populated, we humans generally rarely arrive, coupled with the reduction of the number of some wild animals, the chances of being discovered by us are greatly reduced. If a species has not been found in the wild in the last 50 years, it may be classified as extinct. Of course, it is also possible that this species itself has not yet become extinct, but they have hidden, or migrated to other regions, but we have not found them, so we mistakenly think that they have disappeared and become extinct.
Admittedly, there are some wild animals whose populations are indeed decreasing or even at risk of extinction, but as the environment improves, the number of these wild animals may begin to grow, and when they reach a large enough scale, the probability of us finding them increases greatly. Therefore, the reappearance of species that have disappeared for many years, or even been considered extinct for many years, is actually a relatively normal phenomenon, which is also a evidence that the environment has become better.
< h1 class= "pgc-h-arrow-right" > which species that have been considered extinct but have emerged</h1>
Yangcai arm golden turtle
As early as 1982, the large beetle of the Yangcai arm golden turtle had been declared extinct. However, in recent years, many regions have seen this kind of large beetle, indicating that although these large beetles have been declared extinct, they have not disappeared and have reappeared. Some time ago in the Zhejiang region, there was a citizen found a large beetle up to 7 cm long and about 4 cm in width, after expert identification, this kind of large beetle is the Yangcai Arm Golden Turtle, a national second-level protected animal. The staff then released the large beetle back into the nearby woods.
Coelacanth
This large fish, with a body length of about 1.5 meters and a weight of about 50 kilograms, originated 360 million years ago and lived in freshwater and seawater, but they have disappeared more than 60 million years ago. But in 1938, fishermen in the Indian Ocean caught a strange big fish, and after being caught on the deck of a fishing boat, they struggled for more than 3 hours before they lost their breath. Since no one had ever seen this fish, this strange fish was sent to the museum, and after expert identification, this one was a long-extinct empty spiny fish.
Lao rock rat
The Lao rock rat, similar to the aforementioned empty echinos, is a primitive rodent that lived about 11 million years ago and has long since disappeared. But in April 2005, biologists found and even photographed them in Laos.
There are many similar situations, in fact, I will not list them all here. It is reasonable to say that there are some species that disappear for many years but reappear, which can still be explained, such as the large beetles of the Yangcai Arm Golden Turtle, which are themselves small insects, living in the forest, and it is normal that the number is rare and difficult to find. But it seems a little strange that some species that are thought to have disappeared for tens of millions of years, hundreds of millions of years, have reappeared. What do you think?
