How can the sharp -toothing spear mentioned by the Minister of Ecology and Environment disappear for a hundred years?

On September 15th, the Propaganda Department of the Central Committee of the Communist Party of China held a series of theme press conferences of the "Ten Years of China". Huang Runqiu, Minister of Ecological Environment, introduced the situation related to "implementing the new development concept and the beautiful China that builds people and the harmonious coexistence of nature."

At the press conference, when the reporter asked the reporter, Minister Huang Runqiu mentioned that Sichuan's unique endangered plant sharp -toothed spear disappeared for hundreds of years and appeared again. What kind of plant is sharp dental spear? How did you discover it? What stories behind the "hidden world" of extremely endangered plants?

What exactly is a sharp -toothed spear?

Skin -dental spear is a kind of plant unique to Sichuan. In 1908, British botanist Wilson had collected three pointed dental spear specimens in the fruit period in western Sichuan. After more than 110 years, no one found the species.

In August 2021, Hu Jun, a scientific research staff member of the Chengdu Institute of Biology of the Chinese Academy of Sciences, led a team to carry out the second Qinghai -Tibet Plateau scientific investigation research topic "Forest and Shooting Ecological System and Resource Management" Sichuan West Cascine inspection task, in the southeast of Gongga Mountain About 15 doubts of peicular gifted spears were found on the cliff of a gorge of the slope. After the final confirmation, the plant found that the plants were discovered as a sharp -toothing spear.

Its reproduction allowed us to describe and clarify the characteristics of the flower parts of the sharp dental monopoly for the first time, filling a number of wrong morphological features that record attribute information. "Hu Jun said that there are very little volume in the distribution area and population of the sharp -toothing spear. It is mainly growing on the cliffs. It is more sensitive to the light and humidity environment. Human interference may adversely affect its growth.

Hu Jun told reporters that because of the more convenient transportation and the increasing support for basic inspection projects, Sichuan has more detailed investigation in biodiversity, and has discovered many new species and endangered species. It is found that the wild species living body of the sharp -toothed spear can provide the most authentic research materials for subsequent research. It is hoped that it can better protect it by quoting seeds and cultivation, so that it will no longer "disappear".

How to protect endangered species?

Sichuan Province is very rich in biological resources. There are many rare, ancient animals and plants. They are important biological genes in my country and the world. There are more than 10,000 kinds of high plants and more than 1,300 types of high animals in the province. The reproduction of sharp -toothing spear is just an example of the effectiveness of biodiversity protection in our province.

According to Xie Qiang, the director of the Provincial Academy of Sciences, in fact, in order to protect these endangered species, Sichuan has long adhered to the concepts of respect for nature, adapting to nature, and protecting nature. There are currently 530 natural protection sites at all levels, with a total area of ​​120,300 square kilometers; the ecological protection red line is 148,800 square kilometers, accounting for 30.45%of the province's area; and the five biological diversity protection priority areas are clarified. These areas are the focus of biodiversity protection in our province.

In recent years, Sichuan has made a series of measures such as stating the red line of ecological protection, the preferred area of ​​biological diversity protection, the promotion of ecological civilization demonstration creation, and strengthening the supervision of natural protection for natural protection. Large achievements. At present, more than 95%of species resources in the province have been protected through all levels of natural protection and ecological protection red lines at all levels.
