Hair dish, because of its black and slender appearance, is like human hair, so it is called "hair dish". Because of the harmonic sound of hair vegetables and fortune, some places like to eat hair vegetables in order to please the mouth.
But you know what? Hair vegetables are not actually plants, but a member of the blue fungus gate. They are also not endangered, and are widely found in deserts and poor soils around the world. If this is the case, then why does China list hair vegetables as a national-level protected plant?
<h1 class="pgc-h-arrow-right" why is > hair vegetable a protected plant? </h1>
We have the impression that protected plants at the national level are generally endangered organisms, and if they are not protected, they will disappear from the earth. If hair vegetables are not endangered, why protect them?
In fact, the list of hair vegetables as a national first-level protected plant does not protect hair vegetables, but the local ecological environment. Fa Cai prefers arid and semi-arid and barren areas at an altitude of 1000-2800 meters, and these areas are often drought and rain, and the ecological environment is relatively fragile.
We know that the economy of our arid and semi-arid and barren areas is relatively backward, and farmers have low incomes, so that they will get extra income by collecting vegetables.
When local people collect hair vegetables, they usually use methods such as hugging and rake to gather hair vegetables covering the surface of the ground, which will not only damage the local soil surface, but also cause the death of other plants.
In addition, when people collect hair vegetables, they often choose to be in dry and sunny weather, when the moisture in the hair vegetables is low, it is not easy to contaminate the soil, and it is cleaner. But it is precisely because of this that this method of collecting hair vegetables will cause a thin layer of organic matter soil to be destroyed, and will be blown farther away by the wind, exacerbating the degree of desertification of the local soil.
Some people described it as "needing to destroy 10 acres of grassland", while the income of 2 or 2 vegetables is only 40-50 yuan, which is very uneconomical.
In addition, when people are pulling hair vegetables, they will also eat and live on the grassland, in order to obtain fuel, people will directly use local plants as fuel, and the square garden where they live is a few hundred meters bare, posing a serious threat to the entire grassland ecology.
According to statistics, the economic losses caused by China's hair vegetables every year have reached tens of billions of yuan, and the income of hair vegetables is only tens of millions of yuan, which is not worth the loss, so China will list hair vegetables as a first-class protected plant.
The reason why they are listed as plants is actually because people habitually treat them as plants; in addition, in addition, in addition to hair vegetables, there are fewer microorganisms that need to be protected in China; in order to facilitate people's understanding, China has listed hair vegetables as a national-level protected plant.

Similar to the hair vegetable, it is not endangered in itself, but there are many plants that are listed as prohibited for harvesting because of the fragile ecosystem in which they live, such as licorice.
Licorice, like hair vegetables, is more common in arid and semi-arid areas in China, licorice has medicinal value, is the raw material that needs drugs, so local people will dig up licorice to earn income.
However, licorice is more seriously damaged to the local ecological environment than hair vegetables, because the roots of licorice are buried deep under the surface, and in order to obtain the whole licorice, people tend to dig deeper holes downwards to dig the whole licorice.
This excavation method will lead to the destruction of vegetation in ecologically fragile areas, the acceleration of soil desertification, and serious soil erosion. In order to protect the local ecological environment, China stipulates that the indiscriminate digging of licorice is prohibited. However, due to the medicinal value of licorice, China stipulates that the annual excavation plan of licorice should be clearly planned, the area of licorice is listed, and the excavation yield is demarcated, and the no-digging area and the closed breeding area are demarcated. All mining activities are prohibited in the no-dig zone. In the enclosed breeding area, the area, time, method and tool for allowing excavation should be stipulated.
In addition, farmers involved in the excavation of licorice must apply to the relevant departments for a collection permit, the voucher is mined, and the amount of mining must not be exceeded. For areas with a very fragile ecological environment, all excavation activities are strictly prohibited.
It is with these means that the degree of desertification in the arid and semi-arid areas of our country has been reduced. In addition, China has been advocating afforestation, which has restored the ecology of some desert areas in China, and many wild animals that have not been seen for many years have also returned here.

Some organisms are classified as First Class Protected plants and animals because they are scarce, but some are because they have a greater impact on the local ecological environment. Hair vegetables and licorice are such creatures, although they are not endangered themselves, but because they live in a relatively fragile environment, and they have certain economic benefits, if they are not protected, it will cause more serious damage to the local ecological environment.
