"Missing" a hundred years later, it appeared again in Sichuan!

"'Missing' century -old endangered plant sharp -toothing spear has been discovered again." Recently, the reporter learned from the Sichuan Provincial Department of Ecological and Environment that at the "China Ten Years" series of themes held by the Propaganda Department of the Central Committee of the Communist Party of China today, When the Minister of Ecology and Environment Huang Runqiu asked the reporter, he mentioned that Sichuan's unique endangered plant sharp -toothed spear disappeared again for a hundred years.

This gratifying information immediately attracted the attention of the country. What is the story behind the century of the "hidden world" of sharp -toothing spear "hidden worlds"? What kind of plant is it? How did you discover it?

The reporter learned that sharp -toothing 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.

However, 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 conduct a second Qinghai -Tibet Plateau scientific investigation research topic "Forest and Shooting Ecosystem and Resource Management" in the Western Sichuan Western C trhopechua. About 15 doubts of sharp -toothed spear species were found on a cliff on a canyon in the south slope of Shandong. 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 governments for the first time, and filling in a number of wrong morphological characteristics of the attribute information." Very few, mainly growing on the cliffs, which is more sensitive to light and humidity environment, and artificial interference may adversely affect its growth.

Hu Jun revealed that in recent years, due to the more convenient transportation, the support of basic inspection projects has been increasing, Sichuan has more detailed survey 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".

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, under the high attention of the Sichuan Provincial Party Committee and the Provincial Government, the Ecological Environment Department has formulated the "Sichuan Provincial Biological Diversity Protection Strategy and Action Plan (2011-2020)", delineate the red line of ecological protection, and delineate biodiversity A series of measures such as protecting priority areas, promoting the creation of ecological civilization demonstrations, and strengthening the supervision of natural protection grounds and the evaluation of the effectiveness of the protection of nature, our province has achieved great achievements in the protection of biodiversity in our province. 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.
