There are important economic and scientific values of wild plant wild plants. Protecting very small populations can help delay species extinction, maintain ecological balance, preserve resources, and promote sustainable ecological development. It is of great significance for my country's biodiversity protection. Protection of very small groups of wild plants is a national protection action. China Green Times and the China Wild Plants Protection Association will jointly launch the topic of the "China Extremely Small Breed Wild Plants" from March 25 to systematically introduce the characteristics and survival status of some of the very small group of wild plant products in my country, in order to cause the whole society The common attention of the small population wild plants and strengthen the protection of scientific rescue.

Tourist wood

The flowers of sightseeing wood are very small, but the fruits that come out are extremely fat, like a small man with a big fat man. The mature fruits are yellow in the middle, hanging on the old branches, looking at the dragon fruit that seemed to be hanging in the distance.

Sightseeing wood, also known as fragrant flower wood, Xiangmu Nan, and axis. It is a new and new species discovered by Chen Huanpu, a researcher at the South China Institute of Chinese Academy of Sciences. One of the "sightseeing wood" is named to commemorate Mr. Zhong Tourism. Mr. Zhong Yingwang (1868-1940) is one of the pioneers and founders of modern plant classification. China is the first scholar to study plant classification in scientific methods.

Tourism wood is a unique species of a unique species in my country. Only one of these, that is, sightseeing wood, is distributed in southern Jiangxi, Fujian, Guangdong, Hainan, Guangxi, and southeast of Yunnan. Essence As a unique ancient species in my country, the more evolved groups in Mulanke are of great significance to study the classification system of Mulan family, and it has important scientific value for studying the ancient plant districts, ancient geography, and climate. At the same time, sightseeing wood has high ornamental value. The trees of sightseeing are tall and tall, green and beautiful, the flowers are lush, the fragrance is overflowing, and the square is 100 meters refreshing.

Due to the severe flowers and fruits after the flowering wood blooms, it is naturally updated, the population is scattered, and the number is extremely scattered. In addition, it has not been included in the key protection list of my country, and the artificial cutting is severe, which has reduced the sightseeing wood to the dilemma of endangering extinction. At present, the "IUCN" (IUCN) (IUCN) of the World Nature Conservation Alliance has been rated as a danger. We look forward to further protection actions and save the endangered sightseeing wood.

Maozhi five stitches, Jiang Hong, Jiang Hong

Mao Zhi Five Needles are a unique species in my country, also known as the five stitches and southern Yunnan pine in Yunnan. It is distributed in the limestone mountains of 500-1800 meters of altitude of 500-1800 meters in the southeast of Yunnan Province. Mao Zhi five stitches are full of rainfall, warm and humid, deep soil, and good drainage. As a unique species of limestone mountains in southern Yunnan, its distribution area is extremely narrow, scattered, and the number of groups is less than 10, and the number of populations is very small. The number of five -pin pine species of Maozhi has only 358 plants, and only more than 200 adult individuals.

The Kunming Botanical Garden of the Chinese Academy of Sciences conducted a systematic research on the protection of Maozhi five stitches in 1988, and systematically studied its seed storage, seedlings, growth and development rules, and adaptability. In 2015, 25 seedlings were protected in the Kunming Botanical Garden's very small group of wild botanical gardens, marking the preliminary success of the relocation protection of the Kunming Botanical Garden. In 2022, 12 hair branches and five stitches blooming fruit, which marked the basically successful protection of the Kunming Botanical Garden's relocation of the five -needle pine of Maozhi, and continued to carry out in -depth development of Maozhi Five -shot Pine. Protective research and recruitment return practice is of great significance. Jingdong Wingzi Tree

It is only distributed in the unlimited Shandong slope of Wenlong Township, Jingdong County, Pu'er City, Yunnan Province. In the gap, its distribution area is small, and the number of populations is very small. At present, only 25 plants are found. Coupled with the destruction of forests and fields, it is difficult to find the plants of the Jingdong -winged trees, and because it was born in the limestone mountains of the river valley, the vegetation is risk for extinction once it is destroyed. Although its distribution is close to Wuliangshan National Nature Reserve, because it is not in the protected area, the protection management results are limited, and the surrounding area is farmland, which may be disturbed by human production activities at any time.

Jingdong Wingzi Tree has a wide range of applications, with both ornamental, materials and medicinal value. Its trunk is straight and full of tree -shaped shapes, and the shape of the leaves and fruits is unique. It can be cultivated for garden green tree species. At the same time, it is also a large -diameter and excellent material tree species, which preserves its variety of quality resources for future promotion of planting. In addition, this species also has medicinal value. According to the "Selected Herbal Medicine Selection of Simao in Yunnan", the bark of this species can be used as medicine, which has the effects of clearing heat and detoxifying and removing rheumatism.
